The objectives of the project are to assess the viability of performing Revers-Circulation Primary Cementing (RCPC) to reduce circulation pressure requirements for deepwater wells, and to present development strategies for required technologies. If RCPC appears to be feasible for deepwater applications, the concept will be expanded into operational plans to perform deepwater RCPC to illustrate benefits derived from successful implementation. These plans will include contingency operations to cover potential situations that might necessitate plan alternatives
