Mapping

The structure of a fi eld often accounts for the greatest uncertainty in terms of in-place reserves. Getting quick and accurate answers is critical. RMSMapping combines advanced new mapping algorithms with industry standard algorithms. Integrated workfl ows allow geoscientists and engineers to build the structural framework of their fi eld with confi dence.

RMSMapping allows users to map geological horizons in depth or time. It includes the full mapping workfl ow integrated into the E&P industry’s leading reservoir interpretation solution, RMS™.

Fully Integrated, Easy to Use Mapping

RMSMapping offers tight integration with the other RMS modules. This delivers quick iterations during the interpretation phase directly available for the rest of the workfl ow.

All the steps in the mapping workfl ow are included as standard functionality in RMSMapping. The user is not required to run macros or use 3rd party plug-ins to carry out common mapping tasks.

Building, QC and editing the fault model in 3D.

Modern GUI

A modern user-interface with a tree and folder layout of the data allows the user to become familiar with the application very quickly. The RMS project not only allows for all the data to be stored in a single project location but also has full session saving capabilities. All user preferences, views and visual settings are stored as part of the project.

Data Management

Data can be accessed directly through database links to OpenWorks and GeoFrame. Data may also be imported using a variety of fl exible ASCII data loaders or through fi xed fi le formats.

All standard input data types such as lines, surfaces, points and well data are supported. RMS includes utilities for the use and management of datums, projections and local coordinate systems.

IN SUMMARY

Mapping

Time input data and fi nished depth grid.

Surface Gridding Algorithms

A complete range of industry standard and advanced new algorithms are available to allow the fast and accurate mapping of time, depth, thickness and property maps. Algorithms include the Mask method, Local and Global B-spline, Converging average and Kriging.

Structural Uncertainty

The uncertainty of horizons derived from seismic interpretations has a key, but often overlooked, impact on in-place reserves. RMSMapping provides tools for structural uncertainty evaluations, equally important for both development and exploration projects. Multiple realizations of horizons and isochores can be automatically simulated and incorporated in userdefi ned workfl ows. Reserves results are tabulated and comparisons between different realizations can be made graphically using histogram plots. A full range of statistics is also available allowing for the easy extraction of P10, P50 and P90 results.

Depth Conversion

Time horizons and fault data can be converted from time to depth using a 3D velocity model. The velocity model is built by using a variety of user defi ned functions.

Accurate Volumetrics

Comprehensive volumetric analysis from maps is a built in feature of RMSMapping. The user has access to both quick 2D volumetric tools and complete 3D volumetric analysis. Results can be produced by layer, fault block, facies, or license block. Accurate answers are produced as partial cell volume calculations are utilized. Reports are delivered in ASCII or Microsoft™ Excel formats.

Structural Modelling

The internal layering and all faults in your reservoir are quickly and easily built using the RMS integrated structural modelling tool. RMS Structural Modelling can handle thousands of faults and all fault geometries, allowing complicated models to be built without simplifi cation. The horizon model can be generated from any surface data and can easily deal with any repeat sections automatically. The horizon model combines well information and the fault framework to build a complete structural model, also handling unconformities and thickness correction. In addition, high resolution Structural maps can be created. These can display fault pinchouts and shadow contours, and with RMS differing fl uid fi ll can be mapped in separate regions and zones.

Advanced Graphics

Both 2D and 3D views are available for displaying modelling results and QC. The multiview environment allows for montages of both 2D and 3D views to be displayed on a single page together. All data types can be displayed. This includes the seismic, which provides the user opportunity to validate the structural model. Data can be edited interactively in 2D and 3D to ensure consistency.
