Seneca Resources Company and U.S. Well Services Announce All-Electric Well Completion Field Trial WILLIAMSVILLE, N.Y., July 29, 2021

WILLIAMSVILLE, N.Y., July 29, 2021 /PRNewswire/ -- Today, Seneca Resources Company, LLC ("Seneca"), the exploration and production segment of National Fuel Gas Company (NYSE: NFG), and U.S. Well Services (NASDAQ: USWS) ("USWS") announced their collaboration on an upcoming field trial using USWS' Clean Fleet(r) technology to complete a six well pad in Lycoming County, within Seneca's Eastern Development Area. This field trial, which started in mid-July, represents Seneca's first well completions using all-electric fracturing technology and is the latest example of Seneca's focus on greenhouse gas emissions reductions. Results from the field trial are expected to be incorporated into Seneca's ongoing, first-of-its-kind study of available low-carbon well completion equipment, analyzing the emissions data from real-time well stimulation operations.

"As a long-standing sustainability-focused operator in the lowest emissions intensity shale basin in the United States, Seneca continues to look for ways to further reduce its carbon footprint, including the use of best in class emissions reduction practices," said Justin Loweth, President of Seneca. "Our field trial with USWS is another step in this direction, allowing Seneca to evaluate the potential environmental benefits of this well completions solution in our ongoing operations."

"Seneca is a leading E&P operator in the Appalachian Basin that has routinely demonstrated a commitment to reducing the environmental impact of its operations," commented Joel Broussard, the USWS' President and CEO. "We are excited to demonstrate the capabilities of our Clean Fleet(r) technology, especially as Seneca undertakes its detailed study of the emissions performance of various hydraulic fracturing solutions. Our technology has consistently delivered measurable reductions in greenhouse gas emissions, as well as significant fuel cost savings, and we look forward to showcasing these benefits for Seneca."
