An overview of hydraulic fracturing and other formation stimulation technologies for shale gas production – Updated 2015

Report by European Commission’s Joint Research Center, 2015

This report presents an update of the original study carried out in 2013 (EUR 26347). It reviews the latest trends in hydraulic fracturing and alternative fracturing technologies. For each identified technique, an overview is given along with its rationale. Potential advantages and disadvantages are identified and the technological readiness status is identified for its application to shale gas production.

Pure Propane and Non-Flammable Propane Stimulation of Shale

Presentation by John Thrash at the Annual Hydrocarbon Days in Paris, 2014

Technical summary of the properties and performances of ecorpStim’s propane-based waterless fracturing systems: Pure Propane Stimulation (PPS) and Non-Flammable Propane Stimulation (NFP). This document was presented by John F. Thrash, CEO of ecorpStim, at the annual congress of the oil and gas industry in Paris (Annual Hydrocarbon Days) on October 22nd 2014.

An overview of hydraulic fracturing and other formation stimulation technologies for shale gas production

Report by European Commission’s Joint Research Center, 2014

This study, carried out by the European Commission in-house science service in the frame of the internal impact assessment prior to the publishing of the Commission’s guidelines on shale gas in January 2014, provides a snapshot of alternative technologies to hydraulic fracturing for stimulating shale reservoirs, including the propane and non-flammable propane solutions developed by ecorpStim. According to the Joint Research Center, “Liquid propane is particularly suitable for use as fracturing fluid because it is less viscous than water. Many shale formations are water-sensitive, and using LPG would avoid this problem”.

Exploitation of Source Rock Hydrocarbons through Propane Stimulation

Technical addendum to the Montebourg report, 2013

In December 2012, French public experts travelled to South Texas at the request of the French Minister of Industry Arnaud Montebourg to witness a field experiment of pure propane stimulation (PPS) organized by ecorpStim. In February 2013, the experts delivered this technical report to the Minister, and concluded that the technology was very promising and could be adapted to French conditions.
