Paper Number: SPE-200513-MS
... when foams are used to suppress gas kicks under certain well and fluid conditions. More specifically, this study deals with three scenarios: Base Scenario with a relatively short response time such that the injected foams do not contact the formation gas, and Scenario 1 and 2 with a relatively long...

... MPD technology in a deepwater presalt scenario. The MPD system can be divided basically into two parts: (1) the flow deviation system, which enables a closed loop to be created to control flow deviations and (2) the pressure management system, which controls BHP by opening and closing an automated...

... the only viable way to drill some of the challenging wells. In that way, understanding the gas migration behavior while drilling in PMCD mode allows an optimized well design concerning cost and operational safety. The present study validates a mathematical model capable of simulating a scenario where...

Paper Number: SPE-185299-MS
... Abstract When compared to conventional drilling, MPD techniques provide a valuable tool to build challenging wells and reach new reservoirs. As MPD and MCD techniques lead to major changes on the way wells are drilled, the completion projects must be also adapted to this new scenario. In order...
