DEP Issued Violations To Repsol Oil & Gas For Casing/Cementing Failures In 4 Shale Gas Wells After A 34-Hour Uncontrolled Wastewater Release At The Broadleaf Well Pad In Bradford County

The Department of Environmental Protection has now issued violations to Repsol Oil & Gas USA LLC for casing/cementing failures in four shale gas wells at the Broadleaf Holdings well pad in Troy Township, Bradford County after one of the wells experienced an uncontrolled release of wastewater in July. 

There are a total of eight shale gas wells on the Broadleaf well pad.  The four wells with casing/cement failures-- 3H, 5H, 7H and 8H--  all had the same spud date-- February 20, 2025-- the date drilling started.

The other four wells were all drilled in December 2018.

A well control incident on July 13 in the Broadleaf 7H shale gas well resulted in a 34-hour uncontrolled lease of wastewater that spilled onto the well pad and contaminated areas nearby.  Read more here.

Significant cleanup efforts at the well pad continued through August. Read more here.

DEP issued violations related to casing/cement failure in the 7H well on July 13, 2025 and additional for the wastewater contamination [DEP Aug. 28 inspection report].

Monitoring of the 7H well will continue on a long-term basis related to the casing/cement failure, as will an analysis of the well to determine more about its failure and possible corrective measures. DEP inspection report.

In follow-up inspections of the other shale gas wells on the Broadleaf well pad, DEP issued violations to Repsol for defective casing/cementing for three other wells on July 24, 2025-- the 3H well [DEP inspection report], the 5H well [DEP inspection report] and the 8H well [DEP inspection report].

Monitoring of the 3H, 5H and 8H wells will also continue on a long-term basis related to the casing/cement failure, as will an analysis of the well to determine more about its failure and possible corrective measures.

DEP: MarkWest Liberty Midstream Pipeline Construction Results In 36,000 And 29,000 Gallon Spills Into Coal Mine Voids Under Washington County; Total Of 329,900 Gallons Lost So Far On This Project

On
November 25, 2025 and December 1, 2025, the Department of Environmental Protection was notified by MarkWest Liberty Midstream & Resources LLC that horizontal drilling operations on the construction of the shale gas-related Chiarelli to Imperial pipeline resulted in two more incidents of losing drilling fluids into coal mine voids under Mount Pleasant Township, Washington County.

On November 25, 36,000 gallons were lost and on December 1 another 29,000 gallons.  The losses occurred when drilling was at about 110 feet deep. No mine subsidence was reported on the pipeline route that is inspected frequently by the company.

DEP’s Bureau of Abandoned Mines was again notified of the incidents.

MarkWest reported to DEP in a November 26 email that up until that point they had lost a total of 300,900 gallons of drilling fluid into mine voids from this drilling project.

With the December 1 incident that brings the total up to at least 329,900 gallons.

A DEP inspector at the site on November 26 did not observe any drilling fluid on the surface at the construction site.

These were at least the fifth and sixth incidents of this type on this pipeline construction project and they occurred during the drilling of the same general section of the pipeline as the last incident on November 21. Read more here.

No violations were issued by DEP for these latest incidents, so far.
