STWA Successfully Completes Lab Testing AOT in China & Schedules Field Test for August

SANTA BARBARA, CA -- (MARKETWIRE) -- 06/28/12 -- STWA, Inc. (OTCBB: ZERO) ("STWA" or the "Company"), a developer of applied solutions for oil and fuel delivery systems in the multi-billion dollar oil pipeline and diesel engine markets, today announced it has successfully completed lab testing its Applied Oil Technology™ (AOT™) oil pipeline efficiency technology for use in China. This lab test is the first in a three phase process towards full commercial availability of AOT™ in the China pipeline market. Based upon these strong lab test results, STWA is preparing to ship its AOT™ 1.2v to China for field testing, the second in the three stage process, scheduled for late August.

Dr. Rongjia Tao of Temple University, co-developer of STWA's AOT™ technology, conducted the laboratory tests at China Petroleum Pipeline Bureau's (CPP) PetroChina (CNPC) Pipeline Science and Technology R&D Center located in Langfang, China. The center is the sole authority in China that certifies all domestic and foreign products in the pipeline sector. Dr. Tao tested AOT™'s effectiveness in reducing crude oil viscosity on three crude oil samples: Daqing crude oil, Changqing crude oil, and Venezuela crude oil. Each of these varieties of oil is transported via pipelines in China. These test results are expected to yield very specific metrics relevant to the country's pipeline needs.

CPP testing is being conducted in conjunction with STWA's commercialization partner in China, Beijing Heng He Xing Ye Technology Development Company (TDC). As per the terms of STWA's Cooperation Framework Agreement, TDC is responsible for the full costs of implementing the testing and certification of AOT™ with CPP.

TDC's General Manager (CEO), Mr. Zhao Ruilin, commented, "AOT™ is a major global technological breakthrough in reducing viscosity of crude oil, as these test results have shown. The technology offers great social and economic impacts. I believe there is a large national demand for AOT™ in China as it will greatly alleviate the high energy consumption issues that are associated with current oil production and transportation in China."

"Our preliminary results from these lab tests in China are extremely encouraging. We are currently finalizing our analysis of the data and intend to publish results in the very near future," said STWA CEO Mr. Cecil Bond Kyte. "We are very confident that CPP will validate that the results have surpassed initial expectations and that CPP will clear us for moving onto the next phase of in-country testing. This next phase involves field testing our AOT™ 1.2v unit, just as we did successfully at the U.S. Department of Energy's Rocky Mountain Oilfield Testing Facility in Casper, Wyoming."
