Practical Steps To Increase Production and Reserves in Mature Gas Fields: Hugoton and Panoma, Texas County, Oklahoma, U.S.A.

摘要

When working in mature fields, one needs a lot of imagination because many times economic resources are limited. Workovers, that utilize proven and new technology may solve this problem. Using existing wells that already have casing, tubing, artificial lift systems and surface facilities is an excellent way to increase reserves and production with a small investment. Identifying the candidates for the workovers is the key to success. In 2005, 43 wells were worked over in the Texas County, Oklahoma area of the Hugoton and Panoma Fields, resulting in a production increase of 2,914 MSCFD for a total cost of only $1.6 MM. Payout of the program occurred in just 4.6 months, using a conservative gas price of only $3.89 per MSCF. The techniques involved fracture stimulation, mechanical wellbore cleanouts, artificial lift type changes and acidizing. A successful workover program should apply the fundamentals of science and engineering, coupled with field operations and geology. The screening methods developed may lead to further workover activity with anticipated reserve and production increases in other areas of the Hugoton and Panoma Fields.
