Triangle Petroleum Announces Changes to the Board of Directors and Management

Calgary, Alberta - Aug 3, 2007 - Triangle Petroleum Corporation (the “Company” or “Triangle”) (OTCBB: TPLM) today announced the following corporate developments:

Board of Directors:

Mr. David L. Bradshaw, Certified Public Accountant, has been appointed to the Company’s Board of Directors effective immediately. He brings a wealth of public company experience in addition to his financial and management expertise. Mr. Bradshaw spent 20 years with Denver based Tipperary Corporation (“Tipperary”), an AMEX listed oil and gas company that was sold to Santos Ltd. of Australia in 2005 in a transaction valued at $466 million. He was the Chairman and CEO from 1997 until the sale in 2005 and was a key contributor to the growth in Tipperary’s reserve base and shareholder value. Prior to 1990, he was active in a private oil and gas company and employed by several CPA firms. Mr. Bradshaw received his CPA in 1978, an MBA from Texas A&M University in 1977 and a BBA, Accounting from Texas A&M University in 1976.

Mr. Randal J. Matkaluk, Chartered Accountant, has also been appointed to the Triangle Board. He brings a strong track record of starting up and growing a number of successful public and private oil and gas exploration companies from his base in Calgary, Alberta. Mr. Matkaluk was a co-founder and CFO of Relentless Energy Corporation, which was a private exploration and production (“E&P”) company formed in 2003 to focus on natural gas production that was sold in late 2005 at an imputed market price of approximately $63 million. From 1998 to 2003 he was the CFO of several public junior oil and gas companies, which included Antrim Energy Inc., the successful international E&P company primarily focused in Argentina and the North Sea. From 1984 to 1997, Mr. Matkaluk was employed in various management positions with Cube Energy Corp., which was a public E&P company with a production base in Canada of 5,400 barrels of oil equivalent per day. When Cube was sold in 1997 he was the Vice-President, Finance and Administration. Mr. Matkaluk received his Bachelor of Commerce Degree from the University of Calgary in 1980 and his CA designation in 1983.

Mr. John Carlson, who joined the Board of Triangle in June 2005, has resigned in order to focus more of his time and efforts on the public company that he is now actively managing. Mr. Carlson comments, “By introducing Randal to Triangle and understanding David’s background, I am very pleased and confident in the abilities and attributes that these new board members will bring to the Company.”

Mark Gustafson, Chairman, remarks, “With the addition of David and Randal we have now established a five member board, which includes three independent directors and strengthens the Company’s existing corporate governance standards. The reorganized Triangle board provides an effective mixture between technical and financial experience. We especially want to thank John for his two full years of dedication and commitment to our Company.”
