Rockall Energy is the culmination of three companies merged to become one solid, mid-sized oil exploration and production company. We are the combined forces of Arrow Rock, Petro Harvester and White Marlin via a merger that occurred June 6, 2018. Our new identity is symbolic, as it is the name of a small, uninhabited islet in the North Atlantic Ocean (northwest of Ireland) known for being a stopping point for adventurers. Rockall expects to be that... and more. Although our name has changed, our commitment to excellence in the industry, the areas where we operate and to our industry partners remains the same. Together, we are stronger, poised for growth, and will continue to provide upstream exploration and production.
