Description
Lubricating additive for water-based drilling muds RS-201 (horizon ST-7) is designed to be used in fresh, saline, and inhibited drilling fluids when drilling long, directional, and horizontal sections of oil and gas wells on land and at sea. Consists of fatty acid esters. Resistant to calcium aggression, does not cause foaming, even at elevated pH. Does not contain mineral oils and bitumen. Has an increased lubricating effect in the drilling tool-borehole wall system.
