A Legacy

Since the early 1950’s, when the Founder, Seaborn Jacobs, began mining coal, PENNECO and its predecessor companies have been active in real estate and the mineral industries, construction, land development, quarrying, coal mining, leasing, pipeline construction and oil and gas exploration and production businesses.

PENNECO Oil Company was incorporated in 1979 and, since that time, has conducted exploration and production operations in the Appalachian Basin and in many other basins in the continental U.S. PENNECO is active in several shale plays, including the Marcellus and Utica Shales and the Permian Basin.


The PENNECO Management team has an average of over 30 years experience in the exploration and production industry. This expertise has enabled the company to drill many types of conventional and unconventional oil and gas wells in multiple basins nationwide. 

PENNECO is committed to drilling in an environmentally responsible way. Our environmental consciousness has helped to dissipate the stereotype associated with energy extraction. The company takes pride in it’s relationships with surface owners, regulators, and local municipalities.

Building on the legacy of energy production started by Seaborn Jacobs, PENNECO’s business plan is to acquire a diverse portfolio of oil and gas production to minimize risk and maximize return.
