MSE – drilling efficiency evaluation service description

MSE – Drilling Efficiency Evaluation service was born from a research project led by DrillScan, in collaboration with a Major Operator, and several service providers.

Based on DrillScan’s unique Stiff-String model, Torque On Bit (TOB) and Weight On Bit (WOB) can be properly and accurately assessed, using surface drilling parameters as inputs.

Knowing TOB and WOB, Mechanical Specific Energy (MSE), Drilling Strength (S) and Energy (E) can be calculated. By comparing and analysing different indicators based on MSE, S and E, it is possible to determine which type of issues are encountered while drilling (Real Time) or post-mortem.
