DEA Project Number: 146

Project Title: JIP to Develop Hollow Sphere Dual-Gradient Drilling System

Contractor: William C. Maurer, Ph.D. Maurer Technology Inc. 2916 West T.C. Jester Houston, TX 77018-7098 (713) 683-8227 ext. 208

Startup Date: October 1, 2001

Scope of Work: Phase I is to determine the feasibility of developing a dual-gradient drilling (DGD) system that utilizes lightweight hollow spheres instead of seafloor pumps to reduce the density of the mud in risers.

Current Status: This $1.8 million DEA-146 Phase I project was initiated on October 1, 2001, with nine Participants ($200,000 each) and will end on October 1, 2002. This Phase I project has made excellent progress on the possible use of lightweight hollow spheres instead of seafloor pumps to reduce the density of mud in risers. This includes the development of large lightweight particles that can be easily screened out of the drilling mud, methods of pumping and handling these spheres, and on handling kicks with this DGD system. Phase II plans are being formulated to test the system on a shallow land well and then on an offshore well, possibly on a Petrobras rig in Brazil. The work to date shows that this low cost DGD system may be applicable in water depths greater than 2,000 ft due to its simplicity and low cost.

Projected Completion Date: October 1, 2002
