Some of these are monitoring, maintenance, easy access, adjustment and optimization of production. These, along with pressure issues of just getting the oil and gas to the surface, are widely regarded as the biggest reasons that subsea production falls short in terms of ultimate reservoir recovery. The full range of options that exist in very shallow water and land are not yet available for producing from deeper waters. However, the difference in recovery factors, as well as the simple economics of not having to invest in surface real estate, is driving a change.
