Summary
This paper presents the results of a Gas Research Institute funded study to
test the following hypothesis:
"Broad-based benefit is created when drilling organizations systematically cooperate to identify and share successful practices."
To this end, 11 separate successful drilling practices studies (SDP) were commissioned with the following goals: identify the most successful drilling practices for each of the study areas; document these practices in enough detail (in the form of a complete drilling operations plan) to ensure practical application; disseminate the successful practices; and measure the benefit derived from using the successful drilling operations plans.
The studies focus on the following 11 drilling environments:
Greater Green River basin (two studies: South Moxa arch Dakota formation and Wamsutter Almond formation),
Arkoma Basin (two studies: Choctaw thrust and Jackfork plays),
Cotton Valley Reef play in east Texas,
Deep Austin chalk (Texas),
Valverde basin (Straw and Penn sands, Texas),
Anadarko basin (Watonga-Chickasha trend Morrow/Springer formations),
South Texas Gulf coast (Wilcox Lobo trend),
Deepwater (Green Canyon area), and
Extended-reach (South Pass area) drilling in the Gulf of Mexico.
This paper outlines the methodology used to develop these SDP studies, and the benefits reported by operators who have used them. Evidence presented shows that broad-based benefit can be created when drilling organizations systematically cooperate to identify and share successful practices, and that the benefit ranges from 3 to 20% of total drilling costs, with an average benefit on the order of 10%.
