Abstract

Since initial production in early 1990s, the Alpha gas field has been experiencing significant pressure decline. The pressure decline had started to affect the performance of the field; reduced in overall gas production. Subsequently, the extensive pressure decline had caused several wells to collapse due to formation subsidence. The project focused to determine the suitable completion design and casing program for optimum gas recovery from the low pressure environment. The project utilized WellFlo simulation program to compare and analyze the results. Among the identified designs to be simulated are; (1) 10 inch Tubingless Completion (2) Conventional 9-5/8 inch Tubing and (3) Tapered 9-5/8 x 7-5/8 inch Tubing design. The selected design must be able to yield significant increase in gas recovery, extending the producing life of the field and adequate Zonal Isolation to prevent well failure. The 10 inch Tubing1ess Completion had met the required parameters and was selected as the suitable design for the project. The 10 inch Tubing1ess Completion increased gas recovery by 23.15 Percent (%) and extended the producing life of the field up to 16.8 years. In addition, the 7 inch Drill-in Liner provided improved Zonal Isolation between the producing Limestone layer and overlaying Shale structure.
