Solutions for HP/HT

  • HP/HT

Aggressive development of deeper reservoirs globally has greatly increased drilling in the HPHT environment.  HPHT reservoirs are defined as those with bottom hole pressures greater than 10,000 psi (69 MPa), or temperatures greater than 300°F (150°C), where these conditions do not have to be satisfied simultaneously to qualify as an HPHT well. Common challenges in drilling these reservoirs are narrow pore pressure / fracture gradient operational windows.  Non-productive time during these operations can be very high and very expensive.  These challenges more times than not require additional casing strings which can put at risk the planned completion size at TD.

For over 16 years, Enventure has provided SET® openhole liners to enable HPHT wells to reach the planned reservoir by providing extra casing strings when narrow pore pressure / fracture gradient windows have been encountered.  SET® openhole liners have been used specifically to cover transition areas, maintaining the ID necessary to run conventional casing to the planned section TD.  The use of SET® openhole liners has saved hours, days and even weeks of non-productive time, but the greatest value comes from completing HPHT wellbores with the planned ID at TD.

Enventure has a history of technological innovation and a proven record of superior equipment reliability and service.  Of the over 1700 installations of expandable liners that Enventure has made, it has a greater than 97% success rate for the past five years.   Safety is a number one priority for Enventure, and over its history, Enventure has had only one recordable onsite accident (a minor injury) during an installation.
