A proliferation of high-pressure, high-temperature (HPHT) drilling, most recently by North Sea operators, has provided clearer definition of HPHT operating parameters. Pipe to pipe clearances and annulus fluid heat-up contribute to casing and tubular design complexity. Technical aspects of safe drilling and completion are ongoing concerns for HPHT operators and governmental regulatory agencies. HPHT methods and associated completion practices have developed from onshore US and offshore Gulf of Mexico experience. US, Gulf of Mexico, Mobile Bay is one of the most environmentally, technically and operationally challenging E P areas in the world. High investments impact Mobile Bay producers. Average costs per producing well approach $25 million and bring significant production and reserve expectations. This article details remedial work on a high-rate (60 MMcfd), high-pressure (12,500 psi), high-temperature (over 400 F) hostile-gas (about 9% H[sub 2]S and 3 1/2% CO[sub 2]) producer.
