(January 2019) - A leading independent U.S. oil and gas producer selected M&H to provide engineering services for a new produced water treatment facility supporting their operations in the Powder River Basin of Wyoming. M&H launched the project in November 2018 and is providing project management and engineering for process, mechanical, civil, electrical, and instrument disciplines.

“M&H is proud to partner with our clients to support their production operations,” said Paul Jacobs, M&H Director of Business Development. “We appreciate their confidence in our capabilities and look forward to delivering another critical infrastructure project with safety, quality, efficiency, and value.”

The new water treatment facility will separate, filter, and store produced water arriving by pipeline from field operations. Processed water will be reused as needed for continued drilling and fracing operations. M&H will include provisions for subsequent installation of a vapor recovery unit, flare, and associated support equipment to accommodate any future emissions control requirements.

The project is being managed from the M&H Denver location, which opened in the second quarter of 2018.

(January 2018) - In 1978, Ed Maitland and Tom Hoge opened a small engineering firm in Houston, TX. Their goals were simple: innovate, strive for excellence and put the customer first. The oil and gas industry rose and fell and people came and went. But the principles of Maitland and Hoge remained the same.

Forty years later, this legacy lives on as M&H.

Today, M&H offers a complete range of engineering and consulting services for oil and gas applications and serves clients worldwide. After 40 years of service, M&H is an industry leader positioned for continued growth and innovation.
