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.
Capsule and hollow carrier gun systems are available with a wide variety of perforating charges to deliver the perforations needed for the best production or injection.
The Secure2 RF-safe electronic detonator is the fourth generation of S.A.F.E. slapper-actuated firing equipment initiators. This latest iteration provides a step change in performance reliability, with all electronics contained in the detonator package and fully expendable.
The ASFS addressable-switch firing system is run within explosive devices. The system is a series of microprocessors attached to the initiators. Digital communication is used to operationally check and arm the switches. Each microprocessor has a unique address to individually identify the associated explosive device.
