DEA PROJECT STATUS
Status report of a DEA Project

DEA Project Number: 119
Project Title: A Project to Develop Improved Methodology for Pre-Drill Pore Pressure Prediction in Deepwater Wells
Contractor: Knowledge Systems, Inc. 11104 West Airport Blvd. #215 Stafford, Texas 77477 (281) 879-1400
Email: sales@knowsys.com
World Wide Web Site: www.knowsys.com
Startup Date: January 1999
Scope of Work: The DEA 119 Project to Develop an Improved Methodology for Pre-Drill Pore Pressure and Fracture Gradient Prediction for Deep Water Wells began in early 1999 and the first phase was completed in April 2001. The project centered around the collection of data for more than 100 wells in the deep water Gulf of Mexico and the utilization of that data to develop and test new and improved models and methods. There have been a number of significant tasks completed in the course of the project.
Current Status: Phase One ended April 27, 2001. Phase II proposal is being finalized. Phase II is scheduled to begin August 2001.

Business Impact:
Improve accuracy of pore pressure prediction for:

* more efficient well planning
* improved drilling efficiency and safety
* reduce casing related costs
* reduced dependence on contingency casing designs
* optimize hole sizes for maximum production

Technical Objectives:

1. Analyze a number of deep water wells with all available data to include pre drill seismic, log data, mud logging data, etc. to determine actual PP vs predicted PP.
2. Develop an improved methodology for PP prediction for deep water wells.
3. Document methodology in a Recommended Practice Manual
4. Provide a Training Course for Participant Personnel

Methodology:

1. Current industry practice will be reviewed and documented.
2. Each participant will contribute data for 1 to 4 wells under a secrecy agreement that data will not be disclosed to other participants without written permission and will be used only for general PP conclusions.
3. Each well will be analyzed in detail with all available data to determine actual PP and PP mechanism. Various PP models will be utilized in the analysis to determine relative effectiveness.
4. Results will be tabulated and summarized.
5. Recommended practice will be produced.
6. Results will be presented to participants in a series of one day workshops.
7. A training course curriculum will be developed and an initial training course will be held at one site for each participant company

Deliverables:

1. Detailed report of generalized results from analysis.
2. Manual of Recommended Practice
3. Training Course Curriculum
4. Training Course for Participant’s Staff at one location. Additional locations at cost.

Startup Date: May 1, 1998

Project Duration: Six to Twelve Months depending on no. of participants and wells

Project Cost: $140,000 (4 participants min) to $700,000. (20 participants)

Cost per Participant: $35,000.00

Comments: Knowledge Systems has performed pre -drill prediction as well as while drilling analysis for a number of deep water wells in the GOM, West Africa and North Sea.
