Innovative perforating system for deepwater, high pressure, subsea wells
Objectives
  • A major international operator in the Gulf of Mexico with perforating needs had a minimum inflow area requirement of up to 10in2 per foot, however standard gun systems only enabled 39gram 15 shots per foot creating an inflow area up to a maximum of 8in2 per foot 
Expro Excellence
  • Responding to the ITT, Expro modelled the customer’s requirements and provided a technical proposal to meet the required inflow area to achieve expected production rates
  • Expro were awarded the contract and delivered a new charge and gun system: a prototype of this new system was tested in accordance with API RP 19B with a concrete test piece to simulate the reservoir and a section of 101/8” 79ppf SM-125 casing; a second test was also performed on 95/8” 47ppf L-80 casing for comparision
  • The test in the 101/8” casing yielded an inflow area of approx. 14.7in2 per foot 
Value to client
  • The gun system deployment was successful – the customer was able to draw the well down and achieve expected production rates
  • Upon firing, the slight overbalance left in the drill string dropped and the well went static – after monitoring for one hour the well began taking fluid at approx. 10 bbl/hr – confirming the perforations were active
