Expro Excellence
Cased Hole Services Well Intervention and Integrity
Self orientating perforating gun system maximizes productivity
Customer challenges
  • Expro’s customer had a need to perforate their unconventional horizontal wells in the 0° vertical plane, to improve frac performance and to maximize production
  • Gun systems available locally could not meet the desired shot density and toolstring length requirements. The customer wanted to have a system that could run 10 guns per stage, with each gun having 2 shots 6 inch spaced with 0° phasing
Expro Excellence
  • Expro have been performing pump down plug and perforation operations in Argentina since 2017
  • The Expro Argentina team proposed a new self orientating gun system: gravity assisted, roller bearing loading tubes with scalloped gun carriers
  • The new gun system was tested in two wells, as part of which a Multi-finger Imaging Tool (MIT) was conveyed by tractor to verify shot orientation. The MIT survey confirmed 18 out of 20 guns were shot between 330°and 30°. This met the customer’s acceptance criteria
Value to client
  • Our customer now has a solution to successfully perforate their horizontal wells in the 0° vertical plane, to improve frac performance and to maximize production
  • Our customer has also now deployed 248 oriented perforation stages in subsequent well intervention operations
  • This solution has also enabled the customer to recover a well that was mistakenly drilled below the targeted shale pay-zone. By deploying the orientated gun system, the customer was able to perforate and frac up into the pay zone and subsequently produce the well
