About ECORP
In the world of energy, some of the most critical infrastructure is the least visible. This is the story of ECORP International, a company that since 1978, through its predecessors, has quietly become a pivotal player in natural gas storage. The company was co-founded by Dr. John F. Thrash and Mark Green. Dr. Thrash, a former medical doctor, brought a meticulous and innovative approach to the family's energy business, while Green contributed to the founding vision. Their journey wasn't one of flash-in-the-pan success, but of deep industry expertise. As the U.S. deregulated its interstate pipeline system, ECORP emerged as a prolific independent developer of natural gas storage. They focused on a critical need: storing natural gas in depleted reservoirs to ensure supply reliability. The company became known for its technological innovation, particularly with its 'Salternatives Technology,' which utilized horizontal drilling to create high-performance storage facilities. A defining moment for ECORP came with the development of the Stagecoach Natural Gas Facility in New York. This wasn't just another storage site; it was an award-winning project that set new standards for efficiency and environmental consideration. The project's success culminated in a significant event: in 2005, ECORP sold the Stagecoach facility to Inergy, L.P. This sale validated their business model of developing and monetizing high-value energy infrastructure assets. Today, ECORP continues to operate across the energy spectrum, from natural gas pipelines to carbon capture technologies, a testament to its founders' long-term vision.
