Project Number 195
Date of Summary October 1, 1998
Subject Shallow Gas Broaching
Performing Activity Louisiana State University
Principal Investigator Dr. Adam T. Bourgoyne, Jr.
Contracting Agency Minerals Management Service
Estimated Completion September 1997
Description Develop a method for examining the adequacy of planned casing programs for minimizing platform vulnerability to cratering. Some operators use a rule of thumb that a well can be safely shut-in when casing is set at a certain depth. However, that depth is highly variable. This area of well design is currently poorly understood. The information generated by this project will be useful to identify and resolve technological and procedural barriers related to well control for deepwater development in the Gulf of Mexico and California regions as well as arctic drilling in Alaska.
Progress This is an effort between the MMS, LSU, and Petrobras, the Brazilian government oil and gas company.
