Regional insights that pay.
When you specify Westerman equipment, you get a superior product built in a nearby facility — plus process-specific application engineering from a team that knows the everyday production needs and regulatory realities of your basin.
Where we work
Coverage where you operate
Five core basins across the country — each with separation and storage equipment engineered for the local play, the local climate, and the local regulatory environment.

DJ Basin
Colorado, Wyoming
Between intense surface access requirements and aggressive environmental compliance demands, separation and storage equipment in the Niobrara-DJ Basin must be designed with both strength and flexibility. That's why so many operators in the area trust Westerman equipment — compact-footprint units that keep production at peak efficiency, tight-seal fabrication for fugitive-emission control, and remote-monitoring-ready packages for the region's remote locations.

Bakken
North Dakota, Montana
The Bakken's high-pressure wells demand equipment that's up to the job. Westerman equipment is specifically engineered to bring maximum value in this frigid, multi-well pad production environment. With high-IP wells, high water cuts and some of the longest laterals in the nation, Bakken operators rely on Westerman separators built for the pressure, volume and harsh-winter service that the play demands.

Appalachian
Pennsylvania, Ohio, West Virginia, Virginia, Kentucky, Tennessee, Alabama, Maryland, New York
Our equipment thrives on the Appalachian Basin's remote-access well pads, where performance and efficiency are a must. And with our headquarters and manufacturing capabilities in your backyard, area operators have a worthwhile partner that's always on hand. Marcellus/Utica production has driven record demand for gas processing equipment that handles high throughput on hilly terrain — exactly what our compact, high-capacity packages deliver.

Mid-Con
Oklahoma, Kansas, Texas
Westerman helps operators in the Mid-Con specify the perfect separation and storage solutions for any field from the Woodford to the Caney and beyond. And with major manufacturing facilities in Oklahoma, you'll find it's helpful to have a provider close at hand. As activity spreads across the region, Westerman is applying regional expertise — intelligent, high-capacity storage and process flexibility for a region that produces both gas and oil in quantity.

Permian
Texas, New Mexico
In today's Permian Basin, production engineers and asset managers are looking for new and innovative ways to create efficiencies. Westerman's innovative, efficient separation technologies are helping bring more product to market, more quickly. With production volumes that surpass several other oil-producing nations combined, the Permian demands high-efficiency separation, high-pressure well pad infrastructure and aggressive sand removal performance — especially in the sandy Bone Spring and Spraberry formations.
