Propane Fracking
The new alternative to hydrofracking is propane fracking. This is considered the Green alternative when the cracking of rock layers underground is needed to extract a natural gas or oil reservoir that is trapped in shale rock beds.
The principal is basically the same as hydro fracking. Liquefied petroleum gas is pumped down a well bore and into the rock bed in a gel form. This cracks the shale rock bed without the formational damage other fracking methods might present.
One of the leading advantages of using LPG over water and oil based fracking techniques is the recovery of the fracking fluid. Sand and surfactants are used in the typical hydrofracking technique. This waste water then needs to be treated or stored securely after it is used. The propane fracturing technique is different.
The LPG method places the LPG in the well bore as a liquid or gel and upon completion of the fracking procedure it is withdrawn as a gas. Unlike the hydro fracking technique that takes up to 5 days to extract 50% of the hydrofracking medium, with LPG the time is only 24 to 48 hours at a rate of nearly 100%.
The recovery of this propane gas is done along with the same pipeline used to collect the natural gas. This allows for the elimination to flare sales gas for a week or more as which is common with hydro fracturing techniques. There are even conservative estimates that this procedure increases the productivity of a well by 35%.
LPG is a highly flammable gas but is safe to work with in gel form. This is the form that is used in propane fracking for the natural gas industry.
