True Drilling LLC began in 1948 when H.A. ‘Dave’ True, Jr. and Douglas S. Brown formed a partnership known as True and Brown Drilling Contractors. Then in 1953, the partners established True and Brown Oil Producers. In 1954 Brown sold his interest to Dave and Dave earned a new business partner, his wife, Jean Durland True.

For almost 70 years, True Drilling has remained family owned and operated based out of Casper Wyoming. True Drilling LLC operates in the Rocky Mountain area and beyond. 

We are a contract drilling company, drilling for oil and natural gas using rotary rigs up to 1500hp.
