OCS Offshore Well Completion Data

What is a well completion?  It's the operations that prepare a well bore for producing oil or gas from the reservoir. The goal of these operations is to optimize the flow of the reservoir fluids into the well bore. A completion is the process of making a well ready to produce natural gas or oil. Completion involves installing permanent equipment, such as a wellhead, and often includes hydraulic fracturing.

Search Criteria
Ar/Blk Enter the Area/Block Code
Water Depth (Low & High) Enter the low & high water depth range for your search. For example you may want to see all completions in the Ship Shoal area between 100 and 200 feet of water only.
Start & End Date Enter the starting and ending completion date range. For example you may want to find all wells having a completion date between 1995 and 1996 in the East Cameron area.
