Shallow Gas Reservoir Case Study


In order to develop a deepwater shallow gas field, the feasibility of drilling a relief well, to intersect the planned vertical producing wells, had to be proven. The relief well would need to build to at least 90° inclination to achieve the required surface location separation. The relief well would need to reach horizontal far shallower from the seafloor than had ever been achieved worldwide, and high doglegs would be needed in ultra-soft formation.
