Pressworks™ Relational Database
Geopressure Data Management
Geopressure data is an important aspect of reducing risk and enhancing drilling performance. But the data is diverse, is often of unknown quality and comes from many sources. As a result, realizing its true value is difficult.
The Pressworks™ relational database is designed specifically for storing and managing geopressure data. Tightly integrated with the Drillworks® suite of geopressure and geomechanical analysis applications, the database enhances data value through:
- Improved access
- Quality assurance
- Security
With the database, engineers and others involved in the planning and real-time management of drilling operations have greater access to a broad range of relevant information, including:
- Well logs
- Geopressure data
- Analyses from pore pressure and geomechanics experts
Access, Quality and Security
The Pressworks database system stores data, provides access through an easy-to-use interface and enhances sharing for planning and drilling operations. It adapts to operator needs with user-defined fields and queries, and facilitates access to key sources of data from third-party databases. The result is an enhancement of multidisciplinary collaboration and well planning.
Tight integration with Drillworks software allows Pressworks users to streamline project development through an integrated family of software for geopressure and geomechanical analysis.
In addition to serving as a corporate store for pressure-related data, Pressworks can also connect to industry standard databases, proprietary data stores and commercial data vendors over the Internet.
Users can work on projects using the applications in Drillworks, then upload results to Pressworks so that data of known quality can be assured for users who browse or use Drillworks results.
Two components of the Drillworks software suite provide graphical user interfaces to access the data stored in the Pressworks system: the Explorer data browser and the Scout data visualizer (designed for non-Drillworks users). With these tools data browsing can be done with either a Windows Explorer-type interface or through a map interface.
Using Drillworks software, the Pressworks database can be accessed to compare data from specific wells in the depth domain by various data types. Wells selected based on attribute and/or spatial queries can be displayed showing user-specified types of data displayed versus depth for a quick, visual display of what data are available over what depth intervals for selected wells.
Once selected, these data can be also be examined in a variety of ways using Drillworks tools, including the Predict log trace viewer, LOT (Leak Off Test) viewer, and the 3D geopressure visualization and analysis tool. The data can also be loaded as a Predict project to help forecast and address pressure-related problems at a single well location.
The results of these efforts, which may be cut and pasted into a spreadsheet or exported as an ASCII file, provide highly flexible output than can be easily applied according to the engineer’s specific needs.
Operators currently using the Drillworks system for geopressure and geomechanical analysis benefit immediately from the Pressworks relational database through:
- Improved integration of regional data and Drillworks analyses
- Enhancement and streamlining existing workflow for the lifespan of a Drillworks project
- Increased corporate security for valuable data and analysis
- Enhancement of non-Drillworks users’ access and use of the analysis through Scout software
Conclusion
With the Pressworks database, geopressure and geomechanical experts spend more time on analysis and less time finding and qualifying data. The streamlined workflow helps implement business rules for improved quality assurance and provides connectors for enhanced data gathering.
The end-result delivers the right data to the right person at the right time, in a way that is useful and meaningful to them.
