摘要

Many cost components must be considered to determine thernmost cost effective deepwater production system for arnparticular site. Too often, only the well systems CAPEX1 isrnadequately included in field development alternative studies.rnOPEX, RAMEX and RISKEX depend largely on reservoirrncharacteristics, specific well system designs and operatingrnprocedures. The effect of these factors nearly alwaysrnoutweigh differences in well system CAPEX. Optimization ofrntotal lifecycle cost of deepwater production systems mustrninclude all of these factors.rnThe risks associated with blowouts are often an importantrnfactor in choosing one dry tree tieback well system overrnanother. Another important factor often overlooked is the costrnof well system component failures. As oil exploration andrnproduction moves into deeper and deeper water, the costs tornrepair well system component failures escalate dramatically.rnThis paper presents the methodology developed by a JointrnIndustry Project to quantify capital, operational, blowout riskrnand reliability costs associated with deepwater well systems.rnFive well systems have been modeled to demonstrate thernmethodology: a dual casing dry tree system, a single casingrndry tree system, a tubing riser dry tree system, a conventionalrntree subsea system and a horizontal tree subsea system. Casernexamples demonstrate the model for these five well systems.rnThe methodology, results and main conclusions from thisrnJoint Industry Project are presented.
