Transcript of Types of Drilling Fluids
Types of Drilling Fluids
• Compressed air
• Air/water
• Air/Polymer
• Water Based Mud (WBM)
• Oil Based Mud (OBM)
• Synthetic Based Mud (SBM)
Functions of Drilling Mud
• Remove cuttings from well
• Maintain wellbore stability
• Cool, lubricate and support the bit and drilling equipment
• Facilitate cementing and completion
Pouring a foaming agent down
Composition of Drilling Mud
• Additives– Bentonite Clay (gel), Barium Sulfate (barite)– Calcium Carbonite (chalk)
• Viscosifiers– Xanthum gum, guar, CMC
• Deflocculants– Acrylates, Polyphosphates, lignosulfonates
