Presentation Transcript

    1. PETE 406 - Underbalanced Drilling, UBD Lesson 9 Benefits of Underbalanced Drilling UDM - Chapter 3

    2. Harold Vance Department of Petroleum Engineering Benefits of Underbalanced Drilling Increased Penetration Rate Increased Bit Life Reduced Differential Sticking Minimize Lost Circulation Improved Formation Evaluation Reduced Formation Damage

    3. Harold Vance Department of Petroleum Engineering Benefits of Underbalanced Drilling Reduced Probability of Differential Sticking Earlier Production Environmental Benefits Improved Safety Increased Well Productivity Less Need for Stimulation

    4. Harold Vance Department of Petroleum Engineering Increased Penetration Rate In permeable rocks, a positive differential will decrease penetration because increases the effective confining stress which increases the rocks shear strength Therefore increasing shear stress (by drilling UB) increases penetration rate and increases the chip hold down effect
