STWA, Inc. to Begin Phase II Testing of Technology for Increasing Efficiency of Oil Production and Transportation

SANTA BARBARA, CA--(Marketwire - Apr 13, 2011) - STWA, Inc. (OTCBB: ZERO) ("STWA" or the "Company"), an innovative company creating technology focused on energy efficiency of large-scale energy production and improved fuel economy for diesel fleets, announced today that it is about to begin Phase II Testing of its Applied Oil Technology (AOT™) prototype unit at the U.S. Department of Energy's (DOE)Rocky Mountain Oilfield Testing Center (RMOTC) in Casper, Wyoming, and provided detailed images of the unit.

AOT™ is a revolutionary new technology for lowering extraction and transportation costs for pipeline operators and increasing pipeline efficiency. AOT™ utilizes patented processes that reduce the viscosity of crude oil, which reduces operational power requirements thereby reducing costs and improving margins for pipeline operators. AOT™ has already been proven in laboratory tests to reduce crude oil's viscosity. The full-scale AOT™ working prototype was developed with Colfax Corporation, a global leader in critical fluid-handling products and pump technologies.

"AOT™ has the potential to change the way crude oil is transported around the globe and to generate considerable cost savings for the pipeline industry," stated Mr. Cecil Bond Kyte, Chairman and CEO of STWA, Inc. "This comes at a time when there is growing public pressure to relieve the high cost of oil. A 1% increase in crude oil flow capacity on a 36" wide 2,000 mile long pipeline, with a capacity of 500,000 barrels of oil per day, could theoretically produce an extra 5,000 barrels a day, which equates to an additional value of $182,500,000 per year. With more than 400,000 miles of pipeline in operation around the world, the dollar value impact to consumers and corporations could be in the billions each year."

Phase II testing of an STWA's AOT™ prototype unit, which will be taking place in a real world oil pipeline environment at the U.S. Department of Energy's (DOE) Rocky Mountain Oilfield Testing Center (RMOTC) in Wyoming, is being co-funded under contract with the Pipeline Research Council International (PRCI), a global collaborative research development organization for the energy pipeline industry. The testing will evaluate the magnitude and duration of the viscosity changes, and characterize the potential reduction in power required to pump crude oil due to the application of AOT™ on oil pipelines. Testing is scheduled for mid-April.
