Investigation of Mud Related Wellbore Problems in Drilling Well-A in the Niger Delta Region

Wellbore instabilities due to mud related issues during well construction in the wetland Niger Delta region were analyzed, reviewing A as a case study. Time distribution plots and activity break down summary evaluated for candidate well. From analyses, drill bit bottom hole assembly balling, largely soft sticky reactive gumbo shale with high swelling dispersive tendencies system, severe losses, pack off, pipe stuck potentials kicks are some likely challenges often encountered drilling region. Consequent upon which there would be reduced rate of penetration, tight spot, increased torque drag, seen well-A. The fluids play pivotal roles oil extraction processes their type; design formulation determine ultimate success entire operation overall production performance poorly designed system may trigger wellbore instability that could lead non-productive time, loss equipment, even well, kick blowout scenarios primary secondary barriers. Formation damage occur, ultimately leads reduction permeability poor performance,
