SAN LEANDRO, Calif.—May 2, 2017 — Energy Recovery, Inc. (NASDAQ:ERII), the leader in pressure energy technology for industrial fluid flows, today announced the release of MTeq, a pumping solution engineered to increase productivity and reduce operating costs in the mud pumping process in Oil & Gas drilling applications by rerouting abrasive fluids away from high-pressure pumps. In conjunction with the MTeq product launch, Energy Recovery announces a partnership with Sidewinder Drilling LLC as its first early-stage partner for the solution.

MTeq utilizes Energy Recovery’s innovative PXTM Pressure ExchangerTM technology, currently used globally in desalination, and applies it to the upstream Oil & Gas drilling and mud pumping process. This is in keeping with the central imperative of the company’s long-term strategy to develop derivatives of the Pressure Exchanger technology and subsequently identify channel partners with which to bring new technology to market.

MTeq creates value by protecting pumping equipment in a critical process related to drilling oil and gas wells called mud pumping. During mud pumping, a drilling fluid, also known as drilling mud, is circulated from a mud pit through the borehole to remove cuttings, control formation pressures, and lubricate the drill bit. Although the mud pumping process removes most of the solids from the drilling mud, some debris and sand remains and subjects the pumps circulating the fluid to extreme wear, resulting in burdensome repair and maintenance costs. MTeq is installed as a barrier between the mud pits and the pumps, thereby allowing the pumps to process clean, particulate-free fluid, and not the particulate-laden fluid that lends to component failure.

By requiring pumping equipment to process only clean fluid, MTeq will enable a fundamental shift in drilling rig system level design, allowing for the use of centrifugal pumps, which offer greater reliability and cost efficiency to drilling service providers. Upon this shift, operators will immediately unlock value by reducing pump repair and maintenance costs, reducing planned and unplanned rig downtime, increasing overall operational safety, and decreasing mobilization cost and rig up and down time.

Importantly, Energy Recovery’s early-stage partnership with Sidewinder will allow for product field testing and development, validation of the technical envelope and operational parameters, and ultimately, the definition of the path to full commercialization.

Energy Recovery’s President and CEO Joel Gay stated, “We have severally described our technology value proposition as being ubiquitous; namely that we can create significant value for the industrial end user in any application that presents high flow rates, large pressure differentials and high-capital intensity in the form of pump expenditures. Oil & Gas is the most target-rich industry in this respect, and mud pumping within drilling applications presents a unique opportunity to leverage our fluid physics and material science capabilities to develop and deliver an entirely novel and potentially disruptive technology, the MTeq. Given what appears to be a sustainable market upswing and subsequent recapitalization, we are excited about the prospect of fundamentally changing the rig system-level design through the introduction of centrifugal pumps as substitutes to the incumbent plunger pumps, an option only possible through the integration of the MTeq. We are further enthused to work with a well-respected and technology-focused service provider such as Sidewinder to further validate the MTeq, integrate it into their rig configuration and advance the technology toward full commercialization.”

Mr. Gay continued, “We seek to institutionalize Gatling-like product innovation with the objective of developing one derivative of the Pressure Exchanger annually. The launching of the MTeq is the offspring of this program and is further progress toward the achievement of our long-term strategy. We look forward to collaborating with Sidewinder throughout the field trial process.”

Jon Cole, CEO of Sidewinder Drilling, stated, “We are very pleased to have executed an early-stage agreement with Energy Recovery. We believe that the MTeq pump technology will lead to better drilling performance for our customers; while reducing mud pump downtime and expendable expense. Providing superior drilling performance is critical to our customer relationships. Working with Energy Recovery to validate the MTeq technology will provide benefits to Sidewinder and our customers.”
