Toe sliding sleeve solutions for HPHT wells eliminates intervention saving rig time
Customer challenges
  • Expro approached by a major operator in North America to provide a solution following several sequential failures of their existing provider’s toe sliding sleeve
  • Scope of work had extreme HPHT wellbore parameters:
  • –  Bottomhole temperature (BHT) of approx. 320°F (160°C), with plans to hold the tool downhole for up to 90 days before opening
  • –  Bottomhole pressure (BHP) approaching 19,000 psi (131.00 MPa)
Expro Excellence
  • Understanding the operator’s critical downhole requirements using Expro’s modelling application an engineered toe sliding sleeve was proposed and approved
  • Bottomhole conditions required seal components and system requirements
  • Modelling indicated that Expro’s toe sliding sleeve should open at approx. 12,320 psi surface pressure – after 40 days cemented downhole and subjected to temperatures of approx. 320°F, the sleeve successfully opened at 11,700 psi
  • Expro team in Oklahoma City built, pressure tested the tool to ensure no leaks, and then installed the tool in the wellbore, with 100% success rate
Value to client
  • The toe sliding sleeve eliminated interventions by coiled tubing saving rig time and improving efficiency for the operator
  • Improved safety due to reduced personnel on location
  • Reduced costs as it allows for several wells to be opened before expensive frac equipment is deployed to location (they can then frac several wells sequentially for maximum efficiency)
