HONG KONG -- (Marketwire) -- 05/22/12 -- Today, www.EquityLeader.com introduced research coverage of Patterson-UTI Energy, Inc. (PTEN) and Oasis Petroleum Inc. (OAS). Full research reports are available to readers at: www.EquityLeader.com/index.php?sm1=PTEN&sm2=OAS.

Economic fundamentals leading into 2012 have set a generally positive pace with GDP growth likely to pick up through the coming year. However, there are several important caveats to note as the world economy continues to face headwinds and risks weigh to the downside. Positive outlooks are conditional on fiscal policy in payroll taxes and unemployment insurance benefits and upon the easing of the European debt situation. A repeat of volatility experience in 2011 is likely in 2012, as perceptions about the strength of the U.S. economy and the euro zone will vary over time as events unfold.

Despite the current situation, our team continues to identify high momentum situations with growth potential -- there remains strong opportunity within careful discretion.
