The GOM Reservoir Engineer will be part of the GOM Asset Dev Department and will support the Gulf of Mexico in managing both short and long term planning as well as in controlling program execution while ensuring compliance with company policies and procedures. This will be done by working closely with the Assets, Plants and Operational Support groups to gather, analyze and reconcile all necessary data to allow execution of these plans.
