GTI announces it has licensed its PerfExtra® hydraulic fracturing technology on an experimental basis to Liberty Oilfield Services. PerfExtra is a patented method for achieving higher efficiencies in perforation breakdown during fracturing with simple and low-risk implementation. The technology promotes breakdown of non-productive perforations and an increase in stimulated rock volume. This can result in improved hydrocarbon recovery, lessening environmental impact without increasing perforating, fluid, or proppant costs.

Under the experimental license from GTI, Liberty plans to test PerfExtra with certain customers in the Denver-Julesburg (DJ) Basin. GTI will leverage its technical knowledge and experience to assist Liberty with development of well-specific PerfExtra designs to support optimal implementation.

“PerfExtra can enhance fracturing efficiency and is compatible with most fracturing approaches in use today. Field results to-date have shown 15 – 25% improvements in the perforation opening of fracture stages, followed by sustained 15% higher initial rates relative to control wells for over a year after start-up,” notes Mike Rutkowski, Senior Vice President, Research and Technology Development. “Liberty is an innovative service company, and we look forward to working with them to integrate PerfExtra to help grow initial well rates, estimated ultimate recovery, and reserves while increasing capital efficiency.”

GTI is working to broadly deploy PerfExtra across all unconventional basins. For more information about licensing the technology, contact David LaMont, GTI Director of Commercialization at 847-768-0586 or
