Coiled tubing CO{sub 2} gas lift evaluated in West Texas
- Shell Western E and P Inc., Denver City, TX (United States)
The Denver Unit is a mature San Andres field in West Texas. It has been through primary production plus waterflood, and is now undergoing tertiary CO{sub 2} water-alternating-gas (WAG) injection. A significant number of the producers are strongly affected by the offset WAG injection well cycle. The wells swing through a broad range of producing characteristics, from mostly liquid to a high gas-liquid ratio, depending on injection fluid and response time. These wide swings cause troublesome failures, a loss in production and lead to higher operating costs. Since late 1995, SWEPI has been testing two CO{sub 2} gas lift installations in the Denver Unit. Results have been mixed to date. Evaluation of the two installations continues.
