Abstract: Extension of Well Life Through Inner Liner Technology, Rate and Reserve Impacts in the Long Beach Unit, Wilmington Field

HARR, MICHAEL, THUMS Long Beach Co., Long Beach, CA

THUMS Long Beach Company has been successfully running inner liners in wells that have lost sand control for several years. The size of these inner liners has decreased over the years. In 1999, THUMS ran its first 1.9-inch inner liner. In many cases, the remaining reserves in these wells were not sufficient to justify re-drilling the well. This paper will explore the rate and reserve benefit associated with the inner liner program from 1997 through 1999. This paper will assess the reserves preserved by this program.

As inner liners have gotten smaller, some have voiced concerns that productivity and, as a consequence, reserves are reduced. This paper will compare pre-job rate and reserve expectations with post-job rates and reserve analysis. This analysis will provide guidance on the reservoir risk factors that should be considered when evaluating an inner liner project.
