Successful Testing of Extreme HPHT Well in Pakistan: Case History of Qadirpur Deep-1

Abstract

As the search for oil & gas leads to deeper reservoirs, extreme pressures and temperatures have become key considerations in reservoir development. New and innovative technologies are being developed to meet the challenges of evaluating and completing HP-HT wells and bringing these fields on-stream.

In the oil field, wells with bottomhole pressure more than 10,000 psi and bottomhole temperature in excess of 300°F are considered as HP-HT and wells with bottomhole temp in excess of 350°F are considered extreme HP-HT environment. Testing of such extreme HP-HT wells require special testing equipment that can sustain the high pressures and temperatures. The paper presents case history of an extreme HP-HT well, Qadirpur Deep-1, by Oil & Gas Development Co. Ltd (OGDCL) the national company of Pakistan including the planning, design phase, implementation, data interpretation and lessons learned from successful testing operation (BHP = 13,500 psi, BHT  = 377°F and WHP = 10,800 psi). The lessons learned and conclusions made will be helpful in future development and optimization of the new discovered field and other similar HP-HT wells.
