Joint Industry Projects 

Subsalt JIP

The final workshop for the Subsalt JIP was held at the Marriott Town Square hotel in Sugar Land, Texas on October 17-18, 2007. 

The following topics were discussed during this workshop:

• Best practices drilling above, within and below salt
• Salt tectonics
• Using resistivity data for real-time subsalt pressure estimation
• Overview of the Subsalt JIP Atlas of Wells
• Subsalt pore pressure prediction best practices
• Geopressure models for Tahiti, Typhoon and Mahogany prospects
• Discussion of specific wells of interest
• Open Q&A on various research topics

Participation in the subsalt JIP is open to all operators and service companies.  For information on joining the project and participating in future workshops, send an email to info@knowsys.com or complete the Quick Contact form to the right.

More about the Subsalt JIP:

The multi-company research effort is aimed at investigating pore pressure analysis in subsalt and integrating improved seismic imaging with basin modeling.

The goals of the project include:

• Developing state-of-the-art subsalt planning and drilling
• Examining seismic at the well locations for structural effects on pore pressure and for imaging at salt entry/exit
• Building a set of geologic models
• Examining the influence on seismic imaging
• Developing and documenting best practices
  

Conclusions from the project include:

• Large database of subsalt wells analyzed for pressure
• Salinity normalization procedure and analysis
• Vp/Vs pressure analysis - correlation and procedure
• Summary of state-of-the-art subsalt drilling experiences
• Basin modeling improves subsalt predictions
• Basin modeling can impact seismic imaging below salt

DEA 161

Practical Wellbore Stability Prediction Joint  Industry Project

The Practical Wellbore Stability Prediction Joint Industry Project is a multi-company research effort aimed at reducing expensive well construction problems such as wellbore collapse and lost circulation.

Conducted by Knowledge Systems under the auspices of the Drilling Engineering Association, DEA 161 was formed to identify and develop best practices for practical wellbore stability analysis, as well as develop guidelines to assess the relative priority of data types and the minimum data needed for effective modeling.

The project plans to examine about 250 wellbores from five regions around the world. Studies are planned for:

DEA 119

An Improved Methodolgy to Predict Predrill Pore Pressure in Deepwater Gulf of Mexico

The goal of this project was to develop an improved methodology for pre-drill pore pressure prediction in deep water wells. 

The project 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.  Phase 2 was completed in February of 2004.

Upcoming Webinar : Pore Pressure Prediction Techniques

A variety of techniques have been developed to predict pore pressure such that casing and fluid designs can be optimized in advance of drilling.  It is well known that understanding pore pressure pre-drill is essential to well design and the determination of reservoir commerciality.  This webinar will discuss methods of predicting pore fluid pressures in advance of drilling using seismic and geologic modeling techniques.  Best practices for pre-drill pore pressure prediction derived from joint industry research will be presented such that the audience will be able to select the most appropriate modeling method.  To register, click here.
