Patent Issued

The U.S. Patent and Trademark Office recently issued BeneTerra a patent for techniques developed to disperse produced water from coalbed methane wells. The “utility” patent protects subsurface drip irrigation methods developed by BeneTerra to beneficially use coalbed water in a way that limits groundwater impact.

Patent number 7,320,559 is entitled “System and method for dispersing coal bed sodic water.” It was applied for on July
14, 2005 and was awarded on January 22, 2008. The patent reflected the state of the art at the time of application. As
would be expected we have made many improvements in the system since the patent application was made. A second
patent application, a “continuation in part,” was submitted and recently published. More will follow as the BeneTerra team continues to innovate.
