USPTO awards two patents to Millennium

Millennium Stimulation Services said that it has been awarded two patents by the United States Patent and Trademark Office for the use of Energized Natural Gas to perform well fracturing operations. 

One patent relates to Millennium’s foundation application and addresses the system and method of applying natural gas as liquefied natural gas to fracturing fluid mixtures, the company said in a statement.

ENG is a well completion technology which blends natural gas with frac fluids and frac sands into an oil and gas wellbore to fracture a producing formation. Millennium has developed a streamlined and efficient method of pumping LNG in energized or foam frac applications. Energized fracturing has long been known to create above average oil and gas reserves recovery. This is especially true when there is lower flow capacity or potential flow restrictions created from a multiphase flow regime in the formation, the company said.

The other successful patent grant addresses the methodology for creating natural gas fracturing fluids in order to gain the desired behaviors for well fracturing application.

The patents for the same and an additional applications were awarded to the company by the Canadian Intellectual Property Office in February 2015.
