Pense Bros. strives to be the most efficient and cost effective exploration drilling company in the industry. With over 40 years of experience, our customers have come to rely upon us to get the job done at a much faster pace than many of our competitors. Pense Bros Drilling Company was formed in 1962 by Clifford and Ronald Pense in Fredericktown Missouri. The company began by drilling in the lead and zinc fields of southeast Missouri. In the 1970’s Pense Bros. expanded its operations to include exploration drilling in the oil and gas fields of the Arkoma Basin in Oklahoma and Arkansas. During this time, Pense Bros. was one of the first drilling companies to combine air hammers and top head drive rotary rigs in the exploration for oil and gas. This method of drilling allowed for more efficient and more cost effective drilling. By 1988, the company moved into the coal bed methane gas (natural gas) development of The Black Warrior Basin in Alabama. In 1990, operations expanded to drilling for coal bed methane gas in the Uinta Basin of Utah and in 1992 in the Raton Basin of Colorado and New Mexico. Today, most of our operations focus on the exploration drilling of natural gas throughout the United States. We specialize in shallow holes up to 5,000 foot deep. Pense Bros. is among the top 20 land based drilling companies in the United States. Our headquarters are located in Fredericktown, Missouri with branch offices in Glenpool Oklahoma, Trinidad Colorado, and Brookwood Alabama.
