Expro Excellence
Well Intervention
Expro performs CoilHose well jetting remediation on iSSSV
Objectives
  • Customer had a 2 3/8" injection string tubing retrievable injection subsurface safety valve (iSSSV) in the stuck open position
  • Previous mechanical intervention attempts with conventional brushes and exercise tools were unsuccessful
  • A camera run performed identified significant deposits of a heavy grease like substance along the length of the iSSSV which was believed to be preventing the flapper from operating
  • CoilHose was selected as the optimum method for jetting and fluid circulation in order to reinstate the integrity of the iSSSV
  • Contingency operations involved further mechanical intervention to lock out the iSSSV and set an insert valve
Expro Excellence
  • Bespoke engineered solution deploying the latest Expro technology
  • A collaborative approach to developing the well programme with the customer
  • Pre-mobilisation SIT ensured confidence in the effectiveness of the proposed jetting solution
  • Multi-disciplined crew received commendation for contribution to the platform safety processes
Value to client
  • All programme objectives were achieved and integrity restored to the iSSSV
  • Ability to maintain maximum thru bore of 2 3/8" tubing string without the need to lockout iSSSV and set insert valve
  • Safeguarding of future production from the well
  • Two runs performed that included five 'jetting passes' with no miss runs
  • Minimal footprint and rig up time versus conventional coil tubing allowed increased operational efficiency
