CONTROL
Whether you are dealing with a blowout well or a leaking well needing to be plugged, Gunnar is ready to support you.
Catastrophic well control incidents are unexpected and require fast, skilled response. Combining technology, engineering, physics, training, and decades of hands-on experience, our team has successfully responded to numerous out-of-control wells around the world.
We approach each emergency response the same way – with an engineering perspective. Regardless of what kind of environment the uncontrolled release is taking place, our team works efficiently to safely and effectively restore well control.

Caution must be exercised when working on any and all well locations. The safety of our team and those we work with directs everything we do. We work hard to ensure our team has the proper training and equipment to work safely.

Successfully completed well control, well intervention, and complex completions projects

Patents granted and pending patents in ranging technologies

Years experience within the Gunnar Energy Services team

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.

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. Topics discussed are related to well control fundamentals and relief well design and management considerations.

Our team has decades of experience in oil and gas emergency response, relief well planning, well intervention, engineering and environmental services, and pressure control. We’ve managed and assisted operators who have lost access to wells across the country and around the world.



As an independent operator, we’ve worked alongside most of the major players putting us in a unique position to offer an unbiased perspective on well control and plug and abandonment.
When it comes to service providers, we are vendor-neutral and only hire those that have the necessary expertise and are already familiar with your work. You can trust that we’re all on the same team – yours.

With our knowledge and experience, we design a recovery plan, assemble the team and any equipment that may be necessary, and we manage the disaster response to solve catastrophic problems that may otherwise be enterprise-ending.
