Product Information

Koplus® LO is a water and surfactant based drilling fluid pipe release additive which works by dissolving calcium carbonates, and polymers with an aggressive action while drying and cracking clays. It is used in both OBM or WBM stuck pipe applications. Koplus® LO contains a surfactant for removing glycol and oily inhibitors in water based or oil based fluid filter cakes. It can be used to dissolve cement particles as well as collapsed carbonate formations. Used neat, Koplus® LO is normally pumped behind a weighted pill in weighted muds. Like Koplus® LL it has excellent bit and BHA de-balling and cleaning characteristics, but can also be used to clean casing behind OBM displacements when switching over from OBM to WBM as it removes oil film and water wets metal surfaces.

Koplus® LO is also used in some stimulation applications to etch and pinhole the filter cake. The water miscible solvent, strips away any hydrocarbons and reduces any micro-emulsions present. This allows other products that are used, to work faster and more completely. It additionally dissolves CaC03 and other calcium compounds further aiding enhanced production. 

Koplus® LO is also used in descaling operations. It is ideally suited to a wide range of descaling applications as it will dissolve CaC03, asphaltenes, sludge, and wax in the matrix, while dehydrating and breaking up any accumulated clay and shale in the scale matrix. Koplus® LO also has the added advantage of being non-corrosive. 

Koplus® LO is certified within the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) Offshore Chemical Notification Scheme (OCNS) for the United Kingdom and the Netherlands.
