• Controlled Vertical Drift Indicator

    The MD Totco™ controlled vertical drift (CVD) indicator provides accurate drift information at frequent intervals, enabling increased drilling efficiency by maintaining a controlled vertical wellbore. Our CVD indicator offers intuitive use, allowing for simple operation by any member of the rig crew. Easy-to-read charts provide ready access to hole inclination values, allowing the driller to see if the hole is being drilled vertically or if it is drifting. The indicator’s mechanical design, which eliminates ink and electrical equipment, ensures that readings can be acquired without the encumbrance of additional products.
