Micronized barite fluid helps Brazilian well walk narrow drilling window

摘要

Drilling highly inclined wellbores poses two key challenges for operators: avoiding nonproductive time (NPT) from drilling fluid and well control issues, and ensuring ample signal strength for measurement-while-drilling (MWD) tools that guide decisionmaking at the surface. These dual challenges were met in a field trial conducted by Schlumberger and Petrobras using the M-I SWACO WARP oil-based treated micronized barite drilling fluid system (OB TMB) in the 8(1/2)-in. interval in a well offshore Brazil.
