Innovative Solution for High Temperature High Gas Rate Carbonate Well

摘要

Completing an over-pressured N field carbonate reef pinnacle gas reservoir with temperature above 170°C and relatively high concentration of CO2 and H2S can be tough.It gets tougher when in a high rate gas production,and the completion operation is managed in total losses condition.This paper presents the challenges,solutions and hindsight views of completion of high temperature high gas rate carbonate well with PMCD Top Kill Method via deployment of dual 7" and 4-1/2" liner string which are successfully accomplished in all 5 wells.
