Advanced Gulf of Mexico Pressure and Stress Database

Definitive pore pressure interpretation for hundreds of Gulf of Mexico wells

The advanced Gulf of Mexico Pressure and Stress Database (GOM-PSD) is the most comprehensive, high-quality GOM pressure and stress dataset available.

The database applies best practices born out of multiple joint industry projects and thousands of hours of commercial consulting to GOM public well logs and downhole pressure data. The result provides significant new advantages, including:

More interpreted data types
Higher quality data
Better coverage over all logged shale intervals
Expandability and scalability
Flexible delivery

An Expanded Resource

More Data - A greater range of input data provides a more definitive measurement. The answer is more robust when supported by multiple data sources. While other commercial databases have only a few data types, the Knowledge Systems GOM-PSD provides you with:

OBp derived from density
Pp derived from resistivity
Pp derived from sonic
Pp interpreted based on all input and calibration data
Fp derived from interpreted Pp

Higher Quality - Because so much depends on these measurements, data quality is critical. We use the most advanced industry methods to ensure the highest quality data:

Analysis is calibrated to all available information, including MDT/RFT, gas, drilling events and mud weights
Modeling is done in accordance with industry best practices, including thousands of hours of commercial pressure projects and several joint industry projects focused entirely on pressure prediction
A documented quality control process for each well includes peer reviews of all products by expert pressure analysts and geoscientists

Better Coverage - Knowledge Systems analyses provide coverage over all logged shale intervals, compared to the limited, single-point MDT of other commercial databases.

The database is expandable and scalable to customer requirements:

Choose all or part of the existing library
Select public wells not in the library

Flexible Delivery - Users of Drillworks® geopressure and geomechanical software can receive data in the Pressworks™ database format.

Non-Drillworks users can use *.las files and accompanying attribute logs
CD, DVD, FTP or installed database are all available

A Superior Process

The process used to produce the GOM PSD database yields significant advances in data range and quality.

Overburden is derived using a combination of measured and modeled density and sonic data.

Porosity sensitive measurements such as resistivity and sonic are transformed into pore pressure. The pore pressure is subsequently calibrated to measured data such as MDT/RFT or operational data including mud weight, drilling events and gas.

These analyses are then subjected to a fully-documented peer review process which results in an interpreted definitive shale pressure profile.

A fracture gradient is derived from this definitive pore pressure, and calibrated to leak-off tests. Several additional data integrity and quality checks are performed to conform well attribute and aesthetic properties before the final product is stored in a secure relational database.
