Reserve estimate and development study of titas gas field

Abstract

Titas gas field was discovered 50 miles east of Dhaka in east central Bangladesh. A total of fourteen wells have been drilled to-date in five locations. Production from this field began in April 28, 1968. Until January 31, 2000 the cumulative gas production from A sand was 1.368 TCF. Sands B and C together have produced 0.308 TCF of gas during the same period. Several studies to estimate the total reserve of the field have been undertaken in the past with inconclusive results. Recently drilled development wells have revealed startling new information. With this data and new production data, a better reserve estimate has been performed to determine the gas in place (GIP).At the same time future field performance has been looked into. This study finds considerable additional gas in place in Titas gas field as opposed to the officially declared figure of the reserve. With information from the newly drilled wells, revised subsurface maps have been constructed which supports this finding.
