Fielding

The GasGun is simple and easy to field. The propellant is conveyed to the formation in a high-strength hollow steel carrier under a fluid column that tamps the charge and assures that the energy is restricted to the pay zone (see Energy Loss Calculations). The fluid can be anything compatible with the formation such as fresh water, brine, oil, solvent.

The tool is usually fielded by wireline. It attaches to the wireline like a perforating gun, and is most often run using a casing collar locator. The tool is ignited while being suspended at the correct depth. Pressure control equipment, such as a lubricator, can be used when needed.

The GasGun is compatible with both open hole and cased hole completions. Perforated casing must be of good quality and have proper cement bond.  We recommend a perforation density of at least 6 shots per foot with a 0.375″ entry hole diameter to allow sufficient area for the high pressure gas to exit the pipe.  Perforations that have a large entry hole are preferred over deep penetration.

Typically little or no cleanup is required, and your well can usually be put back on production immediately after the stimulation.
