New tool detects, records downhole perforation shots
The new Gun Shot is a wireless system that detects and records the sound of perforation shots made downhole.
The self-contained system records the sound of perforation shots downhole that normally can’t be heard at the surface. It then transfers the readings produced to a file located on the technician’s laptop.
The system’s on-board memory stores data and prevents it from being lost in the event of a power failure or radio transmission problem. Its cable-free feature also means that the data are of high integrity, as there is no risk of losing data as the result of damage to cables.
The system makes it possible to detect readings as low as 10 hz, which is suited for perforating. It then records these signals into a sound file on the technician’s laptop where they can be played back, printed, and signed off.
Because the system is wireless, it is simple and quick to install. To install and operate the system, the user simply stabs the geophone into the ground, switches it on, heads over to the receiving unit, and begins logging data.
