History

1979: Unit added exploration and production to its operations and made its shares available to the public. 

1988: In early 1988, as a result of its diversifying business activity, Unit reorganized its business operation resulting in its oil and natural gas exploration operations being carried out by its wholly owned subsidiary, Unit Petroleum Company and its contract drilling service being conducted by its wholly owned subsidiary, Unit Drilling Company.

Unit settled a natural gas contract dispute with a major natural gas purchaser. This settlement allowed Unit to receive substantially higher than spot market price for natural gas sold from wells included in the agreement and provided capital to continue our reserve growth.

1991: Unit doubled its proved reserves and its company-operated producing well count in the Texas Panhandle region, one of our primary areas of interest, through a large oil and natural gas producing property acquisition.

1994: Unit completed an acquisition of producing properties in Louisiana, New Mexico, Oklahoma and Texas. The location of these properties enabled Unit to expand its oil and natural gas exploration and production operations in the Gulf Coast and Permian Basin regions. As a result of the acquisition, Unit added a new regional office in Houston, Texas.

1995: Unit's oil and natural gas reserves surpassed the 120 Bcfe mark, classifying Unit as a "mid-sized" oil and gas company. The Company's improving operations and increased visibility in the investment community resulted in several research analysts initiating coverage of Unit with "Buy" recommendations.

2000: Unit acquired Questa Oil & Gas Co. in a stock exchange for approximately 1.8 million shares of Unit common stock. At December 31, 2000, Unit reported proved reserves of 240.7 Bcfe.
