Brief history

Mountain Mud Haulers was established in 1978 as a drilling fluid or “mud” hauling company in Upton, Wyoming. Expanding with the booming oilfield, Mountain Mud Haulers moved to Gillette, Wyoming in 1980. While still hauling for many major drilling fluid companies Mountain Mud Haulers began to resale & distribute drilling mud for themselves. By 1980 resale and distribution of drilling mud and the addition of many new drilling fluids and chemicals as well as pit liners and other specialty products, Mountain Mud Haulers became a full scale mud company servicing areas throughout Wyoming, Nevada, Colorado, and into California. From 1998 through 2006 Mountain Mud Haulers serviced not only oilfield and water well drilling industries but also the up and coming Coal Bed Methane Gas industry in the greater Powder River Basin.

On January 1, 2006 Mountain Mud Haulers was purchased by Mountain Mud Service & Supply, Inc., still locally owned and operated with pride in our work.

Mountain Mud Service & Supply, still stocks full lines of drilling standard and specialty drilling mud and chemical products with the addition of production and work-over fluids, cementing or float equipment, in-stock, and special order pit liners, and erosion controls, as well as rental equipment. We also continue to operate our private fleet of trucks capable of delivering any size of load whenever needed.
