Making History

“Seldom is a person fortunate enough to be a part of real history in the making. I am grateful to be involved with the development of the Bakken that is helping the U.S. to realize energy independence. Through the collective efforts of many entrepreneurs, risk takers and hardworking people, we are truly changing the future of our nation in a very positive way.”

Michael Sweeney, President, The Sweeney Group, LLC


“To be successful at geosteering in the Bakken, it is crucial to understand the geology of the formation and to understand directional drilling. As a geologist, our job performance is measured by our ability to keep the wellbore within the designated target zone without causing a sidetrack. Oil wells drilled within the target zone and without sidetracks will save time and money for the operator.”

Samantha Roberts, Principal Geologist
Roberts Geology Services, Inc.

Keys to Efficiency

"Operators continue to reduce drilling and completion costs through efficiency of scale, especially in multi-well pad drilling. Fracturing technology continues to evolve, with operators using higher quantities of ceramic proppant. Proppant strength, quantity, and placement continue to be the keys to efficiently draining shale reservoirs."

John M. Broschat, P.E., President
Broschat Engineering & Management Services, Inc.


Built on Trust

“For us it’s about our employees and the long-term trust and relationships we have built with our customers. We’ve been a family-owned business in North Dakota for 50 years. We were here long before the Bakken Shale play but the Bakken has allowed us to expand our services and grow our business. These are exciting times and we remain committed to serving our customers’ needs today and into the future.”

Daryl Andersen, President
Ham's Well Service, Inc.
