Covenant Testing Technologies, LLC (“Covenant”) announced today that it has combined with Stuart Pressure Control (“Stuart”) to form the premier provider of Well Flow & Sand Management and Pressure Control Solutions in the Permian, DJ, Eagle Ford and Haynesville. The transaction is a debt-free, equity-for-equity combination whereby Catapult Energy Services Group, LLC, an NGP and NGP Energy Technology Partners portfolio company, and affiliates of White Deer Energy will partner together under common equity ownership in Covenant. Covenant now represents the leading provider of flowback, production and sand management, and pressure control products and associated services. The combined strength of Covenant’s well flow technology and Stuart’s pressure control offering creates the largest independent well flowback and pressure control provider in the Permian, DJ, Eagle Ford, and Haynesville. The combined company’s blue-chip customer base will benefit from the expanded product and service offerings to deliver superior value to their completion, production, and workover applications. This platform drives deeper focus and talent into the areas Covenant and Stuart are known for – well flowback and pressure control. The Company’s pressure control lines now consist of frac stacks, Single Line®, zipper manifolds, wireline PC, drill outs, torque & test, and blow-out preventers (BOPs). The well flow management lines now consist of flowback, well testing, sand management and production site management services. Stuart’s Chairman and CEO, Joe Compofelice, commented, “In this new oil price environment, consolidation in the oilfield services business is necessary, and partnering with Covenant will make us both stronger and able to retain and build on our leading positions in the marketplace.” Jim Burtner, President and CEO of Covenant, will lead the combined businesses. Mr. Burtner has extensive oilfield service experience, largely focused on completions, production services and technologies as a Vice-President of Baker Hughes and Partner at Select Energy Services. Mr. Burtner commented, “By combining our people, assets and systems in accordance with our core values and safety culture, the combined company will deliver superior equipment and service to the well site from frac to production. With our expanded service offerings, our competitiveness in each business line will increase and enable us to be more efficient and cost-effective for our customers. “ Greg Laake will continue as Managing Partner of Catapult Energy Services Group and take a strategic role as Executive Chairman at Covenant. Mr. Laake remarked, “Bringing together two top-flight field organizations under one set of professional management with a strong performance culture makes all the sense in the world.
