ProTerra LCM is a water-based lost circulation additive that does not disturb the emulsion balance of an oil-based mud and can also be used to mitigate losses in water-based muds.


In an oil-based drilling fluid our two-part product, with a cross-linked high viscosity phase distributed throughout the  drilling fluid system, provides the operator with an “on demand” solution for losses when the BN-Booster activator is added to a system pre-treated with E2.


If an LCM pill is desired, the reaction delay for the pill can be controlled by adjusting the concentrations of BN-Booster and allows for the placement of a completely liquid phase, which will then build viscosity and expand into the loss zone once the pill is spotted.
