The changing oil prices have been extending a positive impact on Patterson-UTI Energy, Inc. (NASDAQ:PTEN) shares.

The company’s share went up by 3.01% on Wednesday afternoon following an increase in oil prices. The upward oil price shift was caused by a decline in the level of crude oil in the US inventory, a simple case of the law of supply and demand at play.

The shifting prices are a welcome relief for the company especially following the August share dip that was caused by a decrease in the company’s short interest last month. The company’s shares dropped from 20,259,753 shares on August 14 to 16,466,441 shares on August 30, thus resulting in a short interest of 18.7%. The current short interest ratio stands at 2.5 days based on the average daily volume of 6,638,573 shares.
