Paper Number: SPE-205605-MS
... . It is intentional to seal any gas migration below the DCV. This condition generates differential pressure between the top and below flapper, indicated by the presence of trapped pressure during bleed off. After the DCV safely positioned to closed and pressure completely released, annulus above DCV appraised...

... it was difficult to comply to the software recommended design parameters to achieve optimum mud removal. Assessing mud removal is a critical element in controlling gas migration issues. Mud left either on the formation wall or as a channel will serve after cement setting as a path for gas migration. Poor mud...
