ANCHOR DRILLING FLUIDS, USA, INC. - CASPER, WYOMING (ROCKY MOUNTAIN REGION)

Anchor has been a recognizable name in the drilling fluids industry since the 1970's. The company grew during the 1980's and 1990's from strategic acquisitions and mergers of several independent drilling fluids businesses. Anchor's Rocky Mountain operations were conducted as Unibar Energy Services until acquired by Norway's Anchor Drilling Fluids in 1991. During that same period, the Mid-Continent, Permian Basin, and South Texas regions were operated as Jordan Drilling Fluids.

In 1996, when M-I Drilling Fluids divested Anchor's U.S. assets during its purchase of Norway's Transocean ASA Anchor worldwide operations, Anchor's U.S. operations and Jordan were merged to form Anchor Drilling Fluids USA, Inc.

In July 2005, Bob and Phil West, with the support of American Capital Strategies Ltd., acquired Anchor for the purpose of assembling the best management and operational team in the industry and providing both customers and employees an independent and superior alternative. Subsequently, the company experienced substantial organic growth due to the experience and skill at all levels of the organization and our efforts to continue to reinvest and further develop our resources to better serve our customers.

In that same light, Anchor has also grown through several strategic acquisitions. In 2006, Anchor purchased both Ozark Mud & Chemical Inc., a provider of drilling fluid services and equipment rentals in the Fayetteville Shale, and Toby's Vacuum Truck Service Inc., a fluid-handling business servicing the Piceance Basin. In 2008, Anchor added Advantage Drilling Fluids which offers innovative products and quality trained personnel for the drilling and completion fluids needs in the Rocky Mountains.
