Coterra “Software Glitch” Releases Up to 700K Gal. of Freshwater
On April 5 (Easter Sunday), Coterra Energy reported that approximately 400,000 to 704,000 gallons of freshwater were released from an impoundment at the Brooks shale gas well pad in Susquehanna County, Pennsylvania. The release began at 8:02 a.m. when all six stanchion valves opened simultaneously, flowing by gravity into a pasture and reaching Meshoppen Creek before being discovered by a landowner’s relative that evening. Coterra attributed the incident to a corrupted software configuration file, which also prevented remote valve closure and disabled electronic notifications.

In July 2022, MDN brought you news of a possible frac-out, or “inadvertent return” that happens when drilling mud pops out of places where it’s not supposed to — places outside the borehole being drilled (see 
If a tree falls in a forest and no one is around to hear it, does it make a sound? Similarly, if a pipeline being drilled loses 28,500 barrels (1.2 million gallons) of nontoxic drilling mud into an abandoned coal mine void, does it matter? The environmental left is attempting to make a big deal out of MarkWest Liberty Midstream’s drilling project in Washington County, PA, in which the company has, over a series of 19 different episodes, lost a cumulative 28,500 barrels of nontoxic bentonite drilling mud into an old coal mine void as it drilled the Chiarelli to Imperial Pipeline Project, between October 2025 and January 2026. Bentonite is the same stuff used to make kitty litter and toothpaste. 
On August 17, Eureka Resources’ Williamsport Second Street facility (one of the three wastewater treatment plants previously operated by Eureka) leaked some of its stored untreated frack wastewater, which ended up in the nearby Susquehanna River via a storm drain (see 
On December 17, 2025, a casing failure and loss of well control occurred at one of three wells during fracking operations at a Range Resources pad in Washington County, PA. After gas pressure spiked to 2,000 psi, the company stabilized the well and later installed two kill plugs. Despite Range sending an immediate email notification, the Pennsylvania Department of Environmental Protection (DEP) cited Range for failing to use the required website portal for instant alerts. Additionally, the company missed deadlines for a mandatory Area of Review report regarding potential “communication” with other O&G wells and/or water wells in the area. 
On October 22, Coterra Energy reported a well control incident during fracking the 12H well on the Lauer pad in Susquehanna County to the Pennsylvania Department of Environmental Protection (DEP). A loss of control resulted in the high-pressure release of an unknown quantity of fracking and production fluids, along with natural gas, causing the fluid to “spray” on and off the well pad. Coterra, which was fracking five wells simultaneously, called in Cudd Well Control Services and did not regain control until 49 hours later on October 24, after installing a second bridge plug.

EQT Corporation self-reported a wastewater spill at its Secretariat Well Site in Gilmore Township (Greene County), PA, on October 3. Multiple spots were found after the completions crew removed its containment apparatus from the pad. EQT immediately got to work remediating the site and has (so far) removed 340 barrels of wastewater (14,280 gallons) and 21.5 roll-off boxes of dirt. EQT reported the spill to the Pennsylvania Department of Environmental Protection (DEP) as soon as it was observed on October 3. A DEP inspector finally showed up on October 10. 
On July 3, 2024, the Pennsylvania Department of Environmental Protection (DEP) issued an order to EQT asking the company to produce records as part of the agency’s ongoing investigation into the release of up to an estimated 940,000 gallons of wastewater at the Brova shale gas well pad in North Bethlehem Township, Washington County, and similar failures at six other EQT well pads. The issue revolves around the use of “dump lines” at well pads. EQT states that the DEP’s request for reviewing physical paperwork is onerous, and the agency lacks the authority to regulate dump lines anyway. The DEP wants to ensure that another dump line issue (spilling of wastewater) doesn’t happen.
