SUBJECT: PIONEER SELLS CENTRAL UTAH PLAY; YANKEE RESULTS

DATE: January 28, 2005

        South Jordan, Utah --- Pioneer Oil and Gas (OTC Bulletin Board: PIOL) announced today that it had entered into an agreement with a large independent oil company on the NYSE to sell approximately 91,000 gross acres (34,000 net acres) in the Central Utah Overthrust. The terms call for the immediate purchase of 56,000 gross acres (of the 91,000) with the option to purchase 35,000 more. Additional terms of the agreement including the purchase price are confidential.

One of Pioneer's employees, Michael Pinnell, Exploration Manager, was also the co-author of a seminal article in the Oil and Gas Journal, "Stunning Utah Oil, Gas Discovery Focuses Spotlight on Hingeline", in the January 17, 2005 issue. This article details the exciting developments in the Central Utah Overthrust play.

In another development Pioneer announced that it had completed the Yankee Mine West No. 1 well as a dry hole. This well has helped with defining of the Yankee structure but more follow-up data including seismic is probably needed before drilling another well.
