- Irap RMS Portfolio
- The Irap RMS portfolio consists of seven
interrelated modules that share a common user interface, data
model and visualisation environment. These are:
- RMSgeoform
which, through structural modelling and property mapping, creates
the basis for a company's reservoir model and its fluid flow
performance;
- RMSgeomod which
provides interpolation and object-based modelling techniques
for collecting facies distribution data (the overall characteristics
of a rock on fluid flow) and petrophysical properties key to
increasing oil and gas recovery;
- RMSgeoplex
which captures geologically realistic facies geometries that
are correctly constrained to well and seismic data;
- RMSwellplan
the most user-friendly, efficient and comprehensive well planning
tool on the market today;
- RMSstream which
evaluates reservoir models and helps define flow paths;
- RMSsimgrid
a high quality simulation grid which provides semi-automated,
highly flexible and robust grid generation; and
- RMSflowsim
that integrates dynamic reservoir data with the static model
and offers, for the first time, flow simulation together with
the static reservoir model.
-
- The unified data model helps users to integrate
data at different scales through visual and numerical feedback.
Each module delivers a focused set of technical tools appropriate
to a particular modeling stage. All the modules in the portfolio
may be used interactively or in batch through a workflow. The
Irap RMS portfolio is accessed through a primary module, RMSbase,
which acts as the foundation for all the technical modules. The
modular construction of Irap RMS allows users to scale and customise
the system for implementation in their organisation and to select
the components they require for any modelling discipline. Irap
RMS is an open system. In addition to links to industry-standard
databases, a multitude of ASCII and binary formats as well as
published exchange formats such as RESCUE and ROFF are supported.
The Irap RMS portfolio can also be accessed through the application
programming interface (API) RMSopen. RMSopen allows third-party
applications and our customers' in-house developments to supplement
the functionality in Irap RMS without the hassle of importing
and exporting data. Applications developed with RMSopen may even
be incorporated into a standard Irap RMS workflow, adding further
value.
-
-
- The Tempest Suite
- Tempest is the name for Roxar's suite of
reservoir simulation related software. It consists of the following
modules:
Tempest-View: Tempest-View is a
graphical interactive program that provides simulation pre and
post processing for the following reservoir simulators: MORE,
Nextwell, Eclipse and VIP. Coded in Java, Tempest provides dataset
creation, editing, run control, results plotting and 3D visualisation
on PC and UNIX platforms.
-
- Tempest-Venture: Tempest-Venture
is a functional module in the Tempest suite created as a vehicle
for economic evaluation and risk analysis. This module comprises
an economics facility added to the Data Supervisor of Tempest
on the "Economics" tab. The facility is password controlled,
and so will only appear if the relevant switch has been purchased.
-
- MORE: The MORE
(Modular Oil Reservoir Evaluation) simulator is based on a generalized
compositional solution algorithm. The simulator may be run in
equation of state (EOS) or black oil mode. The only difference
between these two options is in the treatment of fluid properties.
This approach makes it easy to switch between black oil and compositional
simulation methods. Depletion, waterflood, condensate cycling
and miscible gas flood processes can be simulated without changing
simulator.
-
- Nextwell: Nextwell
is a batch simulator used for modeling sophisticated wells and
evaluating their inflow and outflow profiles. It combines a fast
black oil simulation engine with an accurate well model.
-
- PVTx: PVTx
is an Equation of State (EoS) based program for simulating PVT
experiments used in petroleum engineering and simple process
applications. It prepares data suitable for inclusion in many
commercial reservoir simulators such as MORE and Nextwell, Eclipse
and VIP.
-
- Structural Modelling
- Irap RMS offers full 3D structural modelling
capabilities making it easy to establish an accurate reservoir
geometry. The principal module for structural modelling in Irap
RMS is RMSgeoform. Structural modelling plays a vital role in
reservoir description. Irap RMS offers full 3D structural modelling
capabilities making it easy to establish an accurate reservoir
geometry.
-
- Visualisation: The
powerful new visualisation environment in Irap RMS provides a
clear picture of the structural relationships within a reservoir.
The unique MultiViewer allows users investigate and edit data
from different angles in multiple 3D-, map- or section- views,
revealing vital information on the relationships between different
structural elements improving quality control interpretations.
The MultiViewer is especially powerful when combined with volume
rendering of seismic data as a backdrop users gain new insights
into the structure of their reservoir.
-
- True 3D mapping: Complex
mapping tasks are handled in a clear, visual manner in Irap RMS
enabling users who do not have advanced mapping skills much greater
control when defining prospects, performing depth conversion
and early volumetrics and even when creating presentations.
-
- Fault modelling: The
fault modelling in Irap RMS is an ideal blend of automation and
user control. The powerful algorithms that handle complex geometries
such as Y-faults, Xfaults, K-faults, low-angle listric faults
and truncation data for several hundreds faults are combined
with intuitive graphical input facilities and powerful 3D editing.
The entire fault modelling process, including manual input, is
stored and can be defined as a job in the workflow management
system. This makes the entire process repeatable, updateable
and documentable. Fault implementations are considered in structural
and heterogeneity modelling, upscaling, transmissibility calculations
and in dynamic assessment of models.
-
- Fault network: The
fault network generated in Irap RMS is the key to efficient fault
modelling. The network is a graphical representation of relations
between faults, including truncations, crossings, Y-definitions,
lateral extensions and mode of displacements. The network can
be generated automatically, interactively or in combination.
This makes it an extremely efficient way to handle fault relationships,
even in reservoirs with several hundred modelled faults. Once
established, the network guides the fault modelling algorithms
so that they produce fault models that reflect the input data,
and helps the modeller concentrate on structural relationships.
-
- Fault model editing: At any stage in the modelling process, users can inspect
their fault model in multiple views from different angles and
distances simultaneously in the MultiViewer. This assists users
as they work on validating their modelling results. If adjustments
are necessary, these can be made interactively using the extensive
3D editing options within Irap RMS. Manual editing of fault surfaces
and lines is stored and will be taken into account in any subsequent
model updates. In other words, the Irap RMS fault modelling task
takes manual edits into account when the model is rerun.
-
- Modeling: Users
can construct stratigraphic sequences in 3D as a series of horizons
constrained by well data, isochores, trend maps and fault surfaces.
New horizons automatically inherit existing model features such
as fault positions and angles. This improves the speed and quality
of multiple mapped surfaces from geophysical and geological base
information. Common problems such as positioning a stack of geological
surfaces within a geophysically derived envelope are overcome
by advanced fitting techniques. Irap RMS converts line and fault
data from the time domain to the depth domain using a 3D velocity
model using the best function for each stratigraphic interval.
-
- Geomodelling grids: Irap
RMS uses a cellular approach to model the subsurface. Layering
architectures corresponding to the reservoir interval are replicated
in the numerical model. An appropriate geometry for attribute
modelling can then be constructed easily. Erosion of upper and/or
lower bounding surfaces, rotation of the modelling grid, fault
incorporation and control line constraints are all introduced
in an accessible and repeatable manner.
-
- Property Modelling
- The property modelling tasks supported by
Irap RMS range from straightforward interpolation to advanced
and rigorous heterogeneity modelling. The main modules used for
property modelling in Irap RMS are RMSgeomod and RMSgeoplex.
The property modelling tasks supported by Irap RMS range from
straightforward interpolation to advanced and rigorous heterogeneity
modelling. The tools in the portfolio produce 2D or 3D facies
and petrophysical models which are consistent with geological
concepts and field specific data (wells and seismic). Over the
past decade, Irap RMS property modelling methods have been applied
in a large number of oil and gas fields. The technology has a
proven track record of handling situations from early appraisal
work in frontier regions to optimising reservoir management in
mature, giant fields with several thousand wells.
-
- Deterministic: Irap
RMS offers a comprehensive suite of interpolation techniques
for property modelling. In addition to standard methods for interpolation
of well data, Irap RMS offers flexible and powerful trend incorporation
functions to guide property generation. This allows users to
supplement well data with geological knowledge (for example of
diagenetic effects) when modelling key reservoir properties such
as fluid saturations, porosity and permeability.
-
- A choice of facies modelling tools:
Facies:belts: A powerful, pixel-based
method designed to model the stacking of facies belts in progradational,
aggradational and retrogradational depositional systems, such
as siliciclastic and carbonate shorelines. It can also be used
to incorporate facies proportion curves directly. Facies:belts
models are often used to constrain the distribution of smaller-scale
heterogeneities generated using object modelling tools.
-
- Facies:elementary: A
simple-to-use, flexible, object-based modelling technique for
quick evaluation of reservoir heterogeneities.
-
- Facies-composite: A
flexible, object-modelling tool for describing geometries and
geological environments. It is particularly suitable for modelling
reservoirs where the where the shape, size and location of heterogeneities
are critical for reservoir management. Users can choose from
a library of predefined shapes or generate customised shapes
to meet project requirements.
-
- Facies:channels: A
tailored object-modelling tool for describing channel deposits
and can be applied in fluvial, delta-plain and deep-marine settings.
The tool describes three types of architectural element: channels;
crevasse/levee complexes flanking the channels; and intrachannel
heterogeneities such as clay plugs or gravel thief zones.
-
- Facies merging: Facies
modelling results can be combined in any sequence, allowing users
to describe realistic geometries for depositional environments
in both clastic and carbonate reservoirs.
-
- Petrophysics: Realistic
heterogeneous petrophysical models can be generated directly
from well data or constrained by the 3D facies models. The data
analysis functionality in Irap RMS provides all the necessary
input (trends, histograms and variograms) for 3D petrophysical
modelling.
-
- Integration of data: The principle underlying Irap RMS property modelling
techniques is to allow modellers to integrate their geological
knowledge with all available field-specific data. In addition
to correct handling of large numbers of wells, the property modelling
algorithms can also be constrained to detailed multiwell facies
correlations, a variety of 1D, 2D and 3D trends, and seismic
data. The multiwell facies correlations are specified using a
flexible graphical user interface.These correlations can be derived
from sedimentological interpretations, geochemical fingerprinting,
from pressure measurements or production history. If the geological
conceptual model includes gradual proximal-to-distal changes
in the depositional environment, this information can be incorporated
through a variety of user-specified trends. If there is a statistical
relationship between seismic attributes and facies (for example
if channels consistently display low impedance values) this relationship
can be used to constrain the spatial distribution of the heterogeneities.
-
- Management: The
individual facies and petrophysical modelling steps are an integral
part of the WFM system. The modelling jobs for the various reservoir
zones can be constructed and run in batch. This allows for efficient
testing and updating of models as new data become available.
The WFM system also allows users to integrate property modelling
into the total uncertainty modelling.
-
- Reservoir Technology
- When a 3D geological model has been developed
and tested, the results must be made available to fluid-flow
simulators. The main modules for reservoir technology are RMSsimgrid
and RMSstream. When a 3D geological model has been developed
and tested, the results must be made available to fluid-flow
simulators. Irap RMS has set the standard in grid design, scale
change and simulation post processing for many years.
-
- QC simulation grids: In Irap RMS, simulation grids can be constructed to
any required resolution and with complete control of cell geometries.
Tight integration with the geological model produces outstanding
structural consistency. The grid can follow major faults, with
control lines defining its skeleton. Minor faults are automatically
incorporated in a way that honours the requirement for hexahedral
cells. This ensures minimal deviation from an orthogonal grid
and limits numerical error in the simulators. Users can adjust
cell pillars adjacent to faults to ensure geometrical consistency.
Local grid refinements can be built interactively or automatically.
Their grid spacing can be variable (e.g. logarithmic) for an
accurate representation of pressure gradients and coning. Users
can perform grid-quality checks before upscaling and reservoir
simulation. The results of these important checks are available
visually and numerically, helping to ensure that erroneous models
are not transferred to the flow simulator.
-
- Segmentation studies: Segmentation is a new concept for dividing grids into
regions or sectors. This approach facilitates a quicker and more
flexible way to perform, in-depth analysis of important regions
by reducing the amount of data to be visualised and manipulated.
Segments can be defined automatically from a variety of options
or by using flexible graphical tools. Segmentation is commonly
used for extracting sectors from the geological and upscaled
grids and comparing their behaviour during simulation.
-
- Upscaling: Irap
RMS provides advanced flow-based upscaling techniques for permeability
and static methods in order to deal with facies, porosity and
saturations. Unique algorithms that provide a rigorous approach
to the complexity of corner-point geometry power Irap RMS. Users
can select a real flow-geometry option, where a tensor method
operates on the fine corner-point grid, using geological grid
transmissibilities (including non-neighbour connections). The
upscaled permeability tensor can, in a way, take into account
any mismatch in local orientation between the fine and coarse
grids. Users can upscale with different methods into different
segments and homogenise or sample into local grid refinements.
As a result, upscaled grids preserve critical detail in areas
of high flow, while in low-flow areas less accurate, but faster
methods can be applied without sacrificing model reliability.
-
- Streamlines: Irap
RMS contains an innovative, single-phase streamline analysis
tool that can be run on geological-scale models. Fluid-flow trajectories
are calculated from a full permeability distribution within faulted
models. Time-of-flight results are generated from these trajectories
and provide potential fluid-front distributions and fluid-delivery
times to producers. This simple, but powerful tool, facilitates
model ranking and selection, well-configuration optimisation,
upscaler-selection support, dynamic, volumetric-run support and
a range of other activities.
-
- Post-processing: The
reservoir modelling process is not complete until the impact
of heterogeneity on fluid dynamics is fully understood and predictions
match production history. Irap RMS allows users to examine simulation
results in detail. Irap RMS makes it easy to cycle through time
in steps. Dynamic parameters can be copied into the geological
grid, creating a direct link between flow paths and reservoir
description and driving history matching from a realistic, geological
perspective.
-
- Well Planning
- The design and drilling of extended-reach,
horizontal and multilateral wells require close cooperation between
drilling and geoscience disciplines. Improve target selection
and well solutions Roxar has an excellent record of success in
well planning and drilling evaluation. Extensive reworking of
our well-evaluation methodology has delivered a unique and user-friendly
well-assessment tool, RMSwellplan. This module provides a graphical
method for users to track their geological and drilling targets
at the same time. An important element of the process is the
interaction between the geological construction of a well such
as geo-target generation from a 3D model and the constraints
imposed by the physics of drilling. Users whether modellers,
drilling engineers or both can digitise well trajectories in
3D and have the supporting algorithms to correct them within
defined drilling constraints. Full visualisation of geological
and drilling attributes is supported. The data model allows users
to separate geological and drilling targets from wells while
retaining full access to previously drilled or planned well trajectories.
Multiple coordinate, unit and reference systems are handled concurrently
to facilitate multidisciplinary cooperation. Decision making
for alternative target and well solutions is supported within
Irap RMS. Tools to design and evaluate trajectories are provided,
allowing users to quickly check alternative solutions. All users
can monitor the evaluations of any discipline. The results from
this monitoring process can be simple alarms or detailed reports
depending on the interest of the user.
-
- Target placement: Target
placement can be defined in various environments, including seismic
cubes, 3D geological models, 2D surfaces, and reservoir simulation
models, separately or in combination. The target axis is digitised
directly in 3D, fixing an exact position within the geological
environment that can be checked for geometrical constraints.
The geological target boundaries represent the tolerance volume
for the position of the well trajectory. This volume is a 3D
tube that can be defined automatically or interactively adjusted
to reflect changing geological boundaries.
-
- Well-path designs: Well
paths to connect the surface or slot position to a target are
automatically generated. The tie-in point may be either a wellhead
or a side-track. If targets are grouped together, it is possible
to generate multilaterals or reach a sequence of targets.
-
- Drilling constraints: The drilling constraints associated with a drilling
programme that can be restricted by formation tops guide the
generation of the well path. Users can define the drilling programme
and associated constraints for a project or for each wellbore.
This simplifies the design of well paths and makes the process
much more flexible. The casing programme, survey programme and
drill strings are readjusted according to the predicted intersection
with the horizons that delimit the different drilling phases.
Perform more reliable well-path evaluations Users can calculate
the uncertainty associated with wellbore position from a survey
programme. This information is then used to calculate the driller's
target and to check for potential collision risks with neighbouring
wells. The driller's target is calculated from the geological
target boundaries and the uncertainty of the planned wellbore
position. The anti-collision scanning process involves simulating
the trajectory of the well, which is then compared visually with
the proximity of the uncertainty volume of the closest wells.
The safety margins for this operation are predefined at the project
level. The mechanical drillability of the well is estimated using
a torque-and-drag model and buckling limits. The friction model
accounts for the stiffness of the drill string and triaxial stress
analysis. The user can choose which drilling mode should be checked
for all, or selected, drilling phases. Optimise well configuration
and scheduling RMSstream helps users to generate dynamically
ranked drainable volumes for a well or set of perforations. This
enhances flow-path determination, well configuration optimisation
and well scheduling.
-
- Data interaction
- Visual inspection and evaluation of the input
data and modelling results, and the ability to interactively
modify both, are essential to the quality and success of modelling.
To meet this, Irap RMS contains an industry-leading visualization
environment and interactive editing functionality:
- multiple 3D, map, intersect and data analysis
views
- visualisation techniques
- tailored interactive editors for all data
types
- printing/plotting.
-
- The MultiViewer: The
most important feature of the visualisation environment in Irap
RMS is the MultiViewer. The MultiViewer allows the user to display
as many 3D, map, intersect and data analysis views as he chooses.
Multiple views can display the same data from different angles,
distances and perspectives. This gives the user unparalleled
control when investigating spatial relationships, quality controlling
input data and modelling results, and interactively editing spatial
data.
-
- Visualisation: In
addition to the MultiViewer, the inclusion of visualisation technology
such as stereo and volume rendering of seismic data allows Irap
RMS to serve any visualisation requirements users may have. This
technology can add value from laptop use to a multi-screen visualisation
environment for the exchange of ideas within an asset team.
-
- Interactive editing: The input data and modelling results used for reservoir
modelling span a whole range of origins, scales and purposes.
To cope with this Irap RMS contains editing tools that have been
tailored to meet the needs of all the data types available. For
example, a simple line editor allows easy modification and supplementation
of seismic interpretations, whereas the well trajectory editor
respects both geological and mechanical constraints. Combined
with the possibilities for quality control offered by the MultiViewer,
this puts the modeller in full control of the task with tools
that are fit for purpose.
-
- Printing/plotting: The
MultiViewer also works as a plotting tool. What you see in the
MultiViewer is what you get on hard copy. As users can format
the page as they wish and add text, arrows, lines and imported
images, etc. high-quality plots can be constructed. Once the
plot is set up it can either be saved to file, to a network plotter
or included as a job in the workflow management. Multiple plots
from multiple realisations can then be produced as the modelling
progresses.
-
- Support tools: To
support the discipline-specific functionality of the commercial
modules in the Irap RMS portfolio, a range of modelling support
tools, which apply throughout the modelling process, is available.
These tools are essential to any reservoir modelling process
and are supplied within Irap RMS at no extra cost.
-
- Data analysis: The
success of any modelling procedure depends on the user,s ability
to assess input and output data. For this reason, data analysis
is available throughout the Irap RMS portfolio, with data of
differing dimensions and scales being treated in a consistent
manner. Data analysis offers easy-to-use and effective tools
for:
- univariate analysis
- multivariate analysis
- geometric and statistical transformations
- variogram generation.
-
- Model manipulation: In
Irap RMS, model attributes can be generated, added or modified
using an intuitive 3D calculator. Users can express functions
such as Levrett J curves as equations and apply nested Boolean
logic. Common uses include volumetric runs, porosity-permeability
transforms, sensitivity analysis and trend modelling.
-
- Well log editor: Using
the flexible well log editor/calculator modellers can generate
new logs or edit existing logs. Generation of logs can be done
using mathematical operations (algebraic, Boolean or logical)
or by sampling parameters. Once the logs have been generated
they may be edited interactively. This allows for the generation
of consistent saturation, completion, facies or any other type
of log necessary for reservoir modelling. The mathematical operations
may be stored inside the project or in a central database to
assure consistency of calculations throughout the lifetime of
the project, even if new wells are drilled or new log surveys
run.
-
- MultiwellViewer: With
the interactive MultiwellViewer, users can quality control well
interpretation, establish well-to-well facies correlations (for
input to facies models) and pick or modify well points.
-
- Programming: Irap
RMS also offers a fully developed programming language for customers
who wish to define corporate or project specific tasks. This
could, for example, include calculation of saturation parameters
based on in-house J curves.
-
- Modelling: Uncertainty
modelling functions within Irap RMS allow users to:
- automate the entire modelling process
- focus on possible reservoir configurations
- generate multiple realisations at each stage
of the modelling process
- assess total reservoir uncertainty.
-
- Volumetrics: RMSgeoform
offers a powerful volumetrics interface that allows modellers
and mappers to derive accurate volumetric data using structure
maps, lease boundaries, property maps, hydrocarbon contacts,
cutoffs and conversion values. Accurate volume data for fields
and prospects are essential factors in any development decision.
Consequently, volumetric analysis must be conducted with great
care at every stage in the reservoir modelling process. In Irap
RMS, the shared drag-and-drop volumetric panel provides comprehensive
support for:
- fast, exact and simple volumetric calculations
- advanced volumetrics based on a geostochastic
approach
- easy handling of different parameter input
leading to scenarios
- to facilitate the evaluation process
- uncertainty handling based on industry-leading
methods
- risk and uncertainty assessment.
-
- Workflow: Irap
RMS consolidates and manages asset value by focusing on critical
workflows such as depth conversion, 3D gridding, volumetrics,
heterogeneity modelling, upscaling and simulator pre- and post-processing.
An integrated workflow management (WFM) system allows common
or repetitive tasks to be captured, automated and documented.
This system allows users to:
- enhance technology transfer and reduce cycle
times
- improve model quality
- perform scenario modelling
- facilitate model maintenance and updating.
-
- Enhance technology transfer and reduce cycle
times Workflows can be edited, extended and transferred between
projects. As a result, standard methodologies can be implemented
quickly and consistently across a project or across several asset
developments and company locations.
-
- Model quality: Data
quality and integrity can be assessed quickly using the WFM system.
Input data, both hard and conceptual, can then be refined and
cascaded into multiple models. The data analysis capabilities
within Irap RMS and the process control offered by the WFM system
help users investigate and compare input and output data in the
modelling sequence.
-
- Scenario modelling: Irap
RMS the ultimate tool for uncertainty and risk analysis, giving
users a powerful model manager and the facility to easily test
alternative interpretation scenarios. Asset teams can analyse
the sensitivity of key reservoir responses to variations and
uncertainties in the input models, thus spanning the risk profile
of proposed actions.
-
- Updating: All
of the user knowledge applied during the modelling process is
captured in the workflows, so updating and maintaining the model
is quick and simple. Users simply load the new data or modify
the settings, then rerun the workflow. The updated output will
reflect both the initial model and the new data.
