***ABOUT TOPCORP***
TOPCORP is a comprehensive, practical training program based on scientific principles for state and federal regulators, field inspectors, and policymakers to better understand the technologies employed in conventional and shale oil and gas field operations. There is no other forum, gathering, or system providing this information to oil and gas regulators and inspectors in the United States.
***TOP ENERGY EDUCATION***
Our educational consortium is composed of Colorado School of Mines, The Pennsylvania State University, and The University of Texas at Austin. Together, we design and create online courses for oil and gas professionals, focusing on the fundamental technology, science, and engineering of oil and gas operations.
