High-Pressure, High-Temperature Drilling

Developing HPHT reservoirs with reduced risk

Schlumberger people, tools, and procedures can help you reduce the risks inherent in drilling and evaluating high-pressure, high-temperature (HPHT) wells. Because each HPHT province presents unique challenges, the key to our success is detailed planning by a trained and experienced team and use of appropriate technology.

Many of our drilling and MWD and LWD tools are available with pressure ratings up to 30,000 psi and temperature ratings up to 392 degF. The proven reliability and survivability of these downhole tools has contributed to the success of HPHT projects once considered uneconomic, in the North Sea and elsewhere.

Proven track records in HT drilling worldwide 

Schlumberger engineers, manufactures, and operates directional drilling and MLWD services, turbines, hydraulic jars, and M-I SWACO drilling fluids rated for HT environments. We have collaborated closely with the United States Department of Energy (DOE) and the United States National Energy Technology Laboratory to develop and test technology rated to 200 degC [392 degF]. 

  • The PowerDrive ICE ultraHT RSS and TeleScope ICE ultraHT MWD service operate durably at 200 degC [392 degF].
  • Neyrfor turbodrills are rated to 260 degC [500 degF].
  • PowerPak HT motors are rated to 190 degC [375 degF].
  • PowerDrive X6 HT RSS and the majority of Schlumberger BHA components are rated to 175 degC [350 degF].

Our wide range of drilling services has a successful track record for HT applications, and our field engineers and maintenance personnel are fully HT certified. Before and after each job, tools undergo the rigorous Schlumberger HT Drilling Maintenance Procedures to ensure optimal performance. Field personnel plan and execute operations according to stringent HT Drilling Operations Procedures.
