Issue 3, 2013 - ecorpStim transforms Eagle Ford shale gas with liquid propane fracturing

ecorpStim modified Eagle Ford shale gas with liquid propane fracturing

eCORP Stimulation Technologies, LLC (ecorpStim), a wholly-owned subsidiary of eCORP International, LLC (eCORP), today announced the success
of a field trial.
During the trial, the company performed 5,950 feet of safe fracturing on
the Eagle Ford shale gas project with a non-aqueous liquid.
This field trial demonstrates ecorpStim's ongoing efforts to advance shale gas development in a sustainable way and minimize its impact on
the environment.

The trial, conducted in Frio County, southwest of Pisol, Texas, was completed
at the end of December.
In the trial, pure liquid propane was the only liquid
used in Eagle Ford shale gas fracturing modifications.
This test differs from the hydraulic or propane gel fracturing methods used in the past in that no chemicals or additives
of any kind were used.
Propane is also commonly used as a household fuel
for cooking, heating, or other purposes.

Dr.
Johnny Kopecky, Vice President of International Operations at eCORP, commented: "The success of this trial means that ecorpStim has taken the first step
towards demonstrating that it is possible to frack shale gas reservoirs with non-aqueous alternatives.
With propane, a liquid object originating from oil and gas reservoirs, we can minimize damage to oil and gas reservoirs without consuming water or treating wastewater
.
The
field trial also used a range of supervisory control and data acquisition techniques to provide a comprehensive evaluation
of the trial.
These methods include downhole microseismic observation wells, installation of a specialized miniature measuring instrument on the string of the treated well to collect downhole pressure and temperature data during treatment, and sampling
of ambient air and noise.

Dr.
John Thrash, CEO and Chairman of eCORP, said: "We are very pleased with
the trial results.
We have always believed that there is a way to achieve sustainable shale gas development, and this trial has proved that there is indeed a viable 'green' alternative to fracturing shale gas
.
" We intend to extend this pilot design concept to further demonstrate the environmental impact
of other innovative drilling technologies we have developed at eCORP.
