How does the GasGun compare
with
other solid propellant
tools?
The GasGun produces several times more gas and
energy than most other stimulation tools using solid propellant (Note: a 3⅜"
x 10' GasGun tool delivers 15,000,000 ft-lb of energy). GasGun
propellant is also significantly more effective in producing fractures since
it uses multi-perforated grains that are progressively burning. This means
that the rate at which the propellant burns increases with time, producing gas
faster as the material is consumed.
The progressive burning is much more effective in
controlling peak pressures and advancing the fractures late in the process
when crack volumes are the greatest. Independent research bears this out. In a
study conducted by Sandia National Laboratories, a multi-perforated propellant
was 300 times more effective in enhancing formation permeability than a
standard solid propellant in a direct side-by-side comparison.
