ECLIPSE 99B & QLA 3.5 Now Commercially Available

Schlumberger Oilfield Services has made its ECLIPSE 99B reservoir simulation software suite and its QLA petrophysical well log analysis and viewing software commercially available. ECLIPSE 99B, which is ready for Y2K, was developed and is being marketed by GeoQuest, a service segment of Schlumberger. The software has been significantly upgraded to include the first commercial release of the FloGeo module for multiphase, multilevel upscaling.

FloGeo, a module of the FloGrid 3D upgriding and upscaling application, accommodates multiphase hierarchical upscaling from core plug to reservoir simulation scale. The upscaling techniques are extensible through a calculator script language and are tightly integrated to the SCAL special core analysis application. SCAL, an ECLIPSE pre-processor, has been enhanced with more curve-fitting normalization, and averaging functions.

FloGrid, an ECLIPSE pre-processor, has additional upgrades. It now allows users to upscale by regions and has new functionality to compare post simulation results with the geological model. Users also will benefit from numerous enhancements made in visualization and grid generation.

Schedule well data transformation software, another ECLIPSE pre-processor, has enhanced templates for plotting and user-definable plotting capabilities.

The ECLIPSE 99B post-processor FloViz now can generate JPEG, TIFF, and PBM files for hard copy output. FloViz also has been enhanced to support derived quantities to display differences in property values calculated during successive simulation runs.

The pre- and post-processors are launched from ECLIPSE Office, the industry's best environment for simulation activities. By integrating the applications and simulators on the ECLIPSE Office desktop, GeoQuest provides an optimized environment for all simulation activities.

Analyzing Well Logs with QLA.

The latest upgrade to QLA petrophysical well log analysis and viewing software, part of the Drilling Office suite of leading-edge drilling applications, is also now commercially available. It links to both the GeoFrame project database and the OilField Manager (OFM) production management software, further demonstrating Schlumberger's commitment to integration and reducing overall workflow cycle time.

"QLA 3.5 is a major release leveraging many new enhancements that enable multiwell analysis, multiwell crossplots, and multiwell reporting for integrated workflows," said Larry Denver, vice president and general manager of Reservoir Software for GeoQuest, a Schlumberger service segment. "The increased power and functionality of QLA combined with access to additional data sources will dramatically help petrophysicists, engineers, and geologists save valuable time as they increase their understanding of reservoir potential."

QLA 3.5 can read Log ASCII Standard (LAS) data as well as data from other sources, including GeoFrame and OFM. Users now can interactively pick markers and perforations on a multiwell canvas for easy correlation of zones and formation tops. This latest release of QLA utilizes irregularly sampled data and bit map images for effective integration of core data into the analysis. Core images can be animated and viewed three-dimensionally so that they are more easily understood by the interpreter.

All of the log, crossplot displays, and reporting tools have been significantly enhanced for truly effective multiwell analysis; many of these new functions can be controlled by a new voice activation system.

QLA is just one of the integrated applications of GeoQuest's Drilling Office that increases the flow of data, allowing drilling teams to work interactively across disciplines and improve decision making.
