Tech Report: KLA-HIB Inhibitor Reduces Mud Volumes, Minimizes Dilution in Sensitive West Siberian Shale

Employing amine-base corrosion inhibitor in sidetrack section reduces costs of waste disposal, enables drilling to TD with no mud losses

KLA-HIB

Publication Date: 11/07/2015

An operator in West Siberia has historically drilled sidetracks using a mud system unable to prevent solids contamination, leading to high dilution volumes. When the cost of waste disposal became uneconomical, the operator requested a drilling fluid with a cost-effective shale inhibitor that could effectively manage dilution and reduce the drilling fluid volume required to successfully drill the section.
