Expro launches 30,000psi perf gun system

Oilfield services firm Expro has launched a new extreme high-pressure tubing conveyed perforating (TCP) gun system, delivering the largest perforation hole area available for frac and gravel pack completions.

Designed specifically for challenging deepwater environments in the Gulf of Mexico, the Extreme Pressure Series 30,000psi TCP gun system uses super big hole charge technology, providing best-in-class area-open-to-flow (AOF) to support frac-and gravel-pack operations. Delivering 18-22 shots/ft using steel HMX charges, standard casing sizes of 7in through 7-3/4in, in combination with the 4 3/4in outer diameter (OD) system, will achieve 6-7in AOF.  However larger casing sizes of 9-5/8 through 10-3/4in, using the 6 5/8in OD system, will deliver a market-leading 13-15in AOF. 

Developed in collaboration with high performance gun system provider, GEODynamics, the system comes with Expro’s fully rated dual hydraulic firing heads and drill stem testing (DST) tools for underbalanced perforating applications.  

Expro’s DST/TCP Global Business Development Manager, Kerry Daly said: “The 30,000psi TCP guns and associated equipment were specifically designed for the deepwater environment, where operators typically frac or gravel pack wells after perforating and require the most AOF possible. Now fully field tested, they can deliver an industry leading perforating hole size for achieving optimal completions and subsequent performance from the well.

“It allows us to bring a key piece of technology to the market place, to support a range of clients due to spud their wells in 2018 – a key driver of this partnership from the outset.”

Expro’s TCP operations are supported from its service centre in Broussard, Louisiana, alongside the Company’s broader suite of subsea, well test, well intervention and fluid product lines across North and Latin America (NLA).
