Gunnar Energy Services Applications Engineering
Recognized expertise in ranging and well control technology.

With over 100 successfully completed well control, well intervention, and complex completions projects, Gunnar Energy Services’ team understands first-hand the technologies and applications necessary for delivering a safe and fit-for-purpose solution.

Clinton Moss, Gunnar’s founder, is recognized as a worldwide expert in magnetic ranging technology and is the inventor responsible for multiple patented ranging technologies.

Prior to launching Gunnar, Moss co-founded Marksman Ranging Technologies.

At Marksman, Moss led all efforts in the invention and production of Marksman’s first proprietary ranging system, the Magnetic Ranging Tool (MRT). After the company was acquired by Scientific Drilling, under Moss’s direction and leadership, Marksman developed multiple magnetic ranging systems deployed under the Scientific Drilling label including the Lodestone, Punchout, SynTrac, and Black Shark active ranging tools.

Gunnar Energy Services Education and Training
Unlike the larger and less–nimble service providers, we’re sharing the knowledge.

Our team has produced a series of educational videos relating to magnetic ranging and well control.

Check out Gunnar’s YouTube channel and come back often for fresh content.

Members of Gunnar’s leadership team are frequently called upon to present at industry conferences and events, as well as provide training for service providers involved in emergency response.
