Long-running Lawsuit Against XTO Energy Over Royalties in W. Pa.
We stumbled across a mention of a lawsuit (Kriley v. XTO Energy) that we previously were not aware of—a lawsuit that had its beginning back in 2019 and involves seven landowners in Butler County, PA. The landowners claim that XTO Energy (a subsidiary of ExxonMobil) systematically underpaid natural gas royalties. Over the past six years, the lawsuit has evolved and was certified as a class action in late 2025, meaning it has expanded from affecting seven landowners to potentially hundreds. XTO, in its latest court filing, is attempting to limit the class action. Read More “Long-running Lawsuit Against XTO Energy Over Royalties in W. Pa.”

On May 20, the Pennsylvania Department of Environmental Protection (DEP) issued notices of violations to XTO Energy, Inc. (a subsidiary of ExxonMobil) for failing to restore five multi-million gallon shale gas freshwater impoundments it used to support fracking operations in Butler County. The impoundments are required to be restored, which includes liners removed and the area regraded to the original contours, within nine months of their last use. 
Pine Run Gathering LLC, a joint venture owned by Stonehenge Energy and UGI, announced yesterday that it had completed a transaction to buy Superior Midstream Appalachian, LLC, for $120 million. Superior Appalachian owns and operates three gathering systems in Pennsylvania, namely Pittsburgh Mills (Allegheny & Butler counties), Snow Shoe (Centre County), and Brookfield (Tioga County). The Pittsburgh Mills system is connected to UGI’s Big Pine gathering system. All three have a combined daily flow of approximately 190 million cubic feet per day (MMcf/d). 
Marathon Petroleum’s MPLX, formerly MarkWest, operates five complexes in the Marcellus shale. One of the five is the Bluestone Complex in Butler County, PA. Bluestone gathers 200 million cubic feet per day (MMcf/d) of natural gas. Bluestone processes 400 MMcf/d of natural gas, separating methane from other hydrocarbons. The facility then further separates ethane (C2H6) from other NGLs like propane and butane in a process called C2+ fractionation—producing some 81,000 barrels per day. Yesterday, MPLX announced that the Bluestone plant has become the only U.S. natural gas processing facility to achieve the EPA’s ENERGY STAR Challenge for Industry. 
PennEnergy Resources, LLC, the 11th largest shale driller in Pennsylvania, agreed to a “deal” with the Biden Department of Justice (DOJ), the Biden Environmental Protection Agency (EPA), and the Josh Shapiro Department of Environmental Protection (DEP) to pay a $2 million fine and spend another $3.6 million on “upgrades” related to air emissions at its well pads. Based on inspections done in 2018 (six years ago!), the EPA accused PennEnergy of illegal air emissions at five “facilities” (well pads) in Butler County, PA. Yet PennEnergy is being forced to “fix” 17 of its oil and gas production facilities and implement “partial measures” at an additional 32 facilities in Butler County and neighboring Lawrence County. 
Yesterday, the Biden Environmental Protection Agency (EPA) and Biden Department of Justice (DOJ) announced settlements with two Pennsylvania shale drillers claiming violations of the federal Clean Air Act and the Pennsylvania Air Pollution Control Act. The Bidenistas alleged that XTO Energy and Hilcorp Energy violated emissions limits at oil and gas production facilities in Butler County, Lawrence County, and Mercer County. XTO is on the hook to pay a $4 million fine, while Hilcorp must pay $1.275 million. In addition, XTO will be made to pay another $1.4 million to plug orphaned wells the company had nothing to do with orphaning. That passes as “justice” with the Bidenistas. 
There were 20 permits issued to drill new shale wells in Marcellus/Utica for the week of Sept. 30 – Oct. 6, down eight from the 28 issued the prior week. The Keystone State (PA) had eight new permits, with five going to Southwestern Energy (now Expand Energy following a merger with Chesapeake) in both Susquehanna and Wyoming counties. The other three permits went to Laurel Mountain Energy for a pad in Butler County.
