KARACHI, July 10 -- Oil & Gas Development Co. Ltd. (OGDC) has made a natural gas and condensate discovery with its Chandio-No. 1 well on Tando Allah Yar block in the Hyderabad district of Pakistan's Sindh province. The exploration effort is a joint venture of operator OGDC, with 95%, and Government Holdings (Pvt.) Ltd. (GHP) 5%.
Chandio No. 1, which was drilled to 3,660 m TD, targeted the Massive, Basal, and A-Sands Cretaceous Age Lower Goru formation. Based on drilling and electric log data, four zones were selected for testing, and hydrocarbons were found in Zone-3 (Massive-Sands) of the Lower Goru formation.
Initial short-duration testing produced 2.45 MMscfd of gas and 70 b/d of condensate at a wellhead flowing pressure of 540 psi through a 32/64-in. choke.
Separately, Pakistan has granted an offshore exploration license to GHPL and has executed a production-sharing agreement with GHP and OGDC for Block No. 2366-6 (Eastern Offshore Indus-A) in the Arabian Sea.
The block covers 2,500 sq km. OGDC said it will invest $2.75 million during the first 2 years of the license's initial term.
