Wireline Perforating

Engineered perforating systems for maximized production

New hardware breakthroughs combined with advanced software modeling enable conducting ultralong and heavy wireline perforating jobs in both offshore and land operations. Using wireline perforating instead of conventional conveyance techniques in deep and complex wells improves efficiency while reducing rig time and cost.

Wireline (or electric line) is the traditional way to run perforating guns and with good reason: Wireline provides the advantages of real-time depth control and selectivity along with reduced logistics compared with deployment on tubing. Although wireline perforating guns were initially categorized by whether they are used before the completion is run (casing guns) or through the completion (through-tubing guns), today any type of engineered perforating system can be run on wireline along with a wide variety of other explosive devices. Regardless of the type of perforating gun, our engineered perforating systems are optimized for the gun and charge combination with respect to the wellbore environment, reservoir and fluid content, and completion geometry.
