Old Dog, New Tricks – How 70-year-old technology still has a role to play in our energy future
Customer challenges
  • A Geothermal customer noticed increased iron counts from one of their producing wells, the well also had a known scale build up issue
  • They had older fields with corrosion issues and wanted to be proactive  with this issue in order to assure the future production
  • The wells were completed with 9 5/8” casing and 7” perforated or slotted liner below
  • The scope was to run a Multi- Finger Caliper to log the entire wellbore, including the liner and casing
  • The downhole temperature was 640°F
Expro Excellence
  • Expro is the market leader for the provision of Geothermal Multi-Finger Calipers and associated expertise
  • The Expro solution meant the customer did not have to “quench” the well in order to log it
  • The Kinley Multi-Finger Caliper and subsequent analysis successfully provided a “snapshot” of the condition of the wellbore, costing the client only hours of shut-in time to log the well
  • Expro provided the Caliper and technician and partnered with a local conveyance company to expedite logistics and minimize costs
Value to client
  • The customer was able to identify casing degradation before it became a serious production issue
  • The Kinley Caliper was the most operationally efficient way for the customer to proactively identify the corrosion and extent of the scale buid-up
  • The customer was then able to implement a solution to remediate the scale build-up and maintain production
