Sand Control Technology

Reliable Wellbore support & Sand control in horizontal well completions. Demonstrated to be one of the safest and most reliable methods of well bore support and sand control, slotted liners are strong, easily installed, and virtually maintenance-free. Providing a rugged screen, they allow formation fluids to enter the well bore with less frictional drag than the lateral wound wire of wrapped screens. At the same time, the longitudinal bevelled slots control incursion problems more effectively than the sharp-edged wide profile holes of wrapped drilled liners.
