Greg Krock is an accomplished litigator who represents clients in matters involving the oil and gas, electric utilities, coal and commodity trading industries. His experience includes litigating contract disputes, unfair competition claims, toxic tort cases, and lease disputes before state, federal and appellate courts.
Greg is well-known in the energy market for his expertise litigating disputes which occur throughout the lifecycle of oil and gas production – from access to mineral rights to supply contracts. For example, Greg has litigated lease disputes with landowners (including bad faith pooling cases), toxic tort claims involving hydraulic fracturing, multi-million dollar contract disputes between drilling companies and their contractors, unfair competition claims against a natural gas service provider, and a myriad of disputes involving the construction of natural gas pipelines.
Greg served as lead counsel in Butler v. Powers, in which the Pennsylvania Supreme Court ruled for Krock’s client, preserving the state’s so-called “Dunham Rule” and affirming that natural gas rights are separate from mineral rights in the state. The opinion protected thousands of lease deals between landowners and developers in the state’s Marcellus Shale region.
In addition to his energy litigation practice, Greg has litigated disputes involving unfair competition, covenants not to compete, trade secrets and confidentiality agreements. He has also represented corporate clients embroiled in financial, contract and shareholder disputes.
In light of his energy-related experience, Greg has repeatedly been asked to speak and comment on oil and gas developments in the Appalachian region. He also periodically speaks at seminars involving restrictive covenants and the protection of trade secrets.
