Expro Excellence
Well Intervention
Downhole video camera used for high temperature geothermal well intervention
Objectives
  • During routine pressure/temperature logging, the incumbent service provider was unable to retrieve logging tools from the client's geothermal wells (>300OF)
  • Assuming there was a casing integrity issue, the client sought an alternative solution to running gauge rings or a caliper log
Expro Excellence
  • Expro's high temperature downhole video was deployed to 971 feet (325OF) and confirmed parted 13 3/8" casing, causing rock and cement entering the wellbore and trapping the logging tools
  • Running additional logging tools could have potentially been caught in the split casing and either damaged or irretrievable
Value to client
  • Running the high temperature camera saved the client 16 hours of rig time and two runs downhole
  • Visualisation of the parted casing provided detailed images of rock and cement through the gapping split enhanced decision making for cost-effective remedial work
  • The client now routinely deploys Expro's downhole video cameras within their maintenance programme (up to twice a year in older wells) due to the fluids in geothermal wells being highly corrosive - invaluable data avoids costly repairs (for example c. $1.5 million to repair the well or c. $5 million to cement the well)
