Expro Excellence
Well Intervention
Expro designs bespoke RCT improving well integrity
Objectives
  • Total E&P contacted Expro to assist with a non-explosive cutting operation.  The objective of this operation was to cut away the flapper lockout tool stuck inside the Tubing Retrievable Surface Controlled Subsurface Safety Valve (TRSCSSV); this was an integrity issue that required an engineered approach, without any damage to the TRSCSSV completion item
  • Due to the narrow restriction of 1.5" in the Flying Lead Orientation Tool (FLOT), another non-explosive solution was not available in the market to cut the FLOT
Expro Excellence
  • Expro proposed the Radial Cutting Service using the MCR oil tools.  Total, Expro, and MCR together have managed to create a bespoke solution for Total by redesigning the current MCR systemand by cutting the FLOT in half, allowing the FLOT to retrieve in two sections
  • The operation was performed in a gas environment, narrow space restriction, shallow depths to be able to cut the 0.375" thick section of the FLOT
  • Using Expro's field experience and MCR's designing services, a solution was created that allowed Total to have the FLOT to be parted in two and no damage to the TRSCSSV component. A special RCT cutter was designed, allowing two cuts to be made at one single point
Value to client
  • Intensive planning resulted in continuous operations with zero NPT
  • By utlising Expro's solution the contracted E-line company was able to minimise the deck space
  • No damage to the TRSCSSV from the RCT cut and well integrity was maintained
  • The solution enabled the well to produce again
