Objective
The aim of the project was to provide geoscientists using GeoScene with a totally consistent 3D representation of one or more surfaces both in cross-section and plan view for developing an interpretation of the subsurface.
This will allow geoscientists to :
* Accurately represent simple and complex geologic structures by constructing
a 3D model from the data provided by means of cross sections.
* Graphically assert data associated with geologic structures.
* Visually check if the Interpretation is compatible with the
geologist's mental image of the field/basin.
* Visually check whether the Interpretation, stored within
the computer, is consistent with observed data.L%
Data Assertion - Work has concentrated on enhancing Data Loaders and incorporating geophysical interpretations into GeoScene. The seismic loaders have been greatly improved. Management utilities of SEG-Y files have been added. A new depth curve loader has been added. Further functionality has been added to the Correlation Builder.
Multiparameter Geometric Database - Work has concentrated on library routines which share interpretations between GeoScene applications. Data structures used in the Correlation Builder, Analysis Tools, Contour Map and Cross Sections have been integrated to make the process of combining picks from different sources much more powerful, faster and more comprehensive. The Data Control Tool enables users to view lists of the current contents of the database. This tool has been modified for closer compliance with Motif Style Guide 1.1.
Interactive Editing/Analysis - Work has concentrated on the Interpretation Editor. In the Section View, the user is able to control relative scale and vertical exaggeration, display and select surfaces, add, delete and edit line segments, text annotations, well deviations and pick locations. The first phase of the Analysis Tools is complete. With these tools, analysis can be carried out over the complete well, between selected interpretation surfaces or selected depth intervals.
Visualisation - Work has mainly concentrated on the Interpretation Editor; the VAST component of the Interpretation Editor is now complete. The Interpretation Editor has been extensively tested at user sites and is now a stable and robust tool. Mobil evaluated the Interpretation Editor in their cross section software selection project. Oilfield Systems is one of three finalists in this Mobil project. The Montage Tool now behaves closer to the "user model" when images are loaded.
Interface - Interpretation Import Tools allow users to load information from external sources. The Interpretation Export Tool allows the user to exportinterpretation data in a variety of ASCII file formats to external applications packages. CGM and RTF filters have been extended. The PICT filter has been upgraded to support PICT II.
Documentation - The GeoScene User's Reference Manual has been constantly updated as development work proceeded with GeoScene and VAST. GeoScene training manuals have been updated to incorporate the VAST components.
VAST (Visualisation, Analysis and Simulation Toolkit), is one of several new modules that has been incorporated into GeoScene, Oilfield Systems' 3D Geological Workstation.
VAST is a next generation hybrid toolkit which will demonstrate the use of a coherent multiparameter object oriented description of the reservoir.
VAST addresses the following :
* Data Assertion - a graphical means of asserting data to generate the Interpretation. These are the data loading facilities provided within the Data Control Tool. Activities include application of software to display well log data and seismic interpretation on the cross section.
* Multiparameter Geometric Database - an extension of GeoScene's object oriented database for storing spatial data which forms the Interpretation . Activities include enhancement of the GeoScene object oriented database to include positional data.
* Editing/Analysis - an interactive editing and analysis facility for modifying asserted data in the Interpretationand visualising the effects. Activities include development of software to allow modification of properties of geologic horizons within the Section View of the Interpretation Editor.
* Visualisation - facilities for viewing various aspects of the Interpretation. The Montage Tool will allow users to assemble a mixed configuration of data, images and interpretations into a single montage. The alternative approach will be undertaken by a 3D modelling package that will have the content of its model controlled by the Section View of the Interpretation Editor. Activities include the operation of third party software or development of software to
(a) provide an easy to use interface for setting up the 3D modelling software,
(b) navigate the Interpretation and extract relevant data for visualisation, and
(c) display of contour information in the Plan View of the Interpretation Editor. * Interfaces - interfaces for importing data to and exporting data from the database. Activities include:develop interface to oil industry mapping packages, develop software to export data from the Interpretation to one or more reservoir simulation packages, and re-structuring and incorporating foreign data into Oilfield Systems' object oriented database. * Documentation - activities include document VAST features within GeoScene's online context-sensitive help and update the hard copy User's Reference Manual to include VAST features.
