SANTA BARBARA, CA--(Marketwire -04/05/12)- STWA, Inc. (OTC.BB: ZERO.OB - News) ("STWA" or the "Company"), a developer of energy efficiency technologies in the multi-billion dollar oil pipeline and diesel engine markets, provided further guidance on how its Applied Oil Technology™ (AOT™) oil pipeline efficiency technology can deliver economic and environmental benefits in the U.S. energy markets.

According to the Association of Oil Pipelines (AOPL), pipelines accounted for 71% of all petroleum transportation in the U.S. in 2008; this is up 66% from 2007 and 54% from 1990. The AOPL provides further data on the superior cost efficiency and safety of pipelines, as compared to alternative forms of transporting oil.

The Company issued a report from the United States Department of Energy earlier today that showed their AOT™ achieved a 40% Pressure Drop Reduction in recent tests done at the Department of Energy's Rocky Mountain Oilfield Testing Center in Casper Wyoming. Last October, the U.S. Department of Energy published tests showing that STWA's AOT could potentially reduce the amount of energy used in transporting oil per mile by as much as 13%.

The U.S. consumes an estimated 19 million barrels of oil per day, with 71%, or 13.5 million barrels flowing through pipelines. At $100 per barrel, this translates into $1.35 billion worth of oil flowing through U.S. pipelines each day.

STWA Chairman and CEO Mr. Cecil Bond Kyte stated, "The test results released today showed that our technology could deliver a 40% pressure drop reduction in oil pipelines. This pressure drop reduction could result in more oil flowing through pipelines. This alone could dramatically impact the industry. The Company has not yet translated the financial impact of how this 40% reduction could impact the industry. Up to this point we have only calculated the financial impact of the 13% energy reduction from results last October." He added, "The cost of transporting $1.35 billion worth of oil per day is significant. AOT™ has been proven to reduce the amount of energy required to move oil by as much as 13%. This potentially means 13% lower oil transportation costs and a corresponding decrease of 13% less greenhouse gas emissions every day in the U.S. We are now in the process of moving towards commercializing of AOT™. Our goal is to advance AOT™ for deployment in the United States and impact up to 71% of the oil that flows through this country."

The Company recently announced agreements towards international commercialization of their technology. In December of 2011, they executed a Letter of Intent to Commercialize AOT™ in China, followed by a Collaboration Framework Agreement with its Chinese commercialization partner in March of 2012. Additionally, in March of 2012, the Company signed Letter of Intent with LG Partners to deploy AOT™ in a multi-national, $2.5 billion, 900-mile oil pipeline.

About AOT™

STWA's Applied Oil Technology™ (AOT™) is designed to allow pipeline operators to temporarily reduce the viscosity of the crude oil within their pipeline(s) to reduce the fluid-drag (also known as friction-loss) between the fluid and the pipeline. By reducing the friction loss, pipeline operators' pump systems require less energy to maintain a constant flow rate, thereby directly reducing daily operation costs.

About STWA, Inc.
