EvoLube G reduces friction in the Evolution system to oil-based mud (OBM)-like lubricity. Accordingly, EvoLube G is especially effective in horizontal applications where it minimizes torque and drag, thereby enhancing transmission energy to the bit and increasing rate of penetration (ROP). Additionally, EvoLube G reduces stick-slip, thereby increasing drilling efficiency and reducing drillstring damage. When used in combination with EvoVis® viscosifier, EvoLube G is especially beneficial in stabilizing non-reactive shales. Control over product quality is assured as EvoLube G is manufactured for worldwide use at Newpark’s Manufacturing & Distribution Facility.


EvoLube G is an effective performance enhancer for all water-based systems and is ideal for high-temperature applications due to its greater than 400°F (204°C) thermal stability. EvoLube G can be used in any type of water-based drilling fluid. Its wellbore lubricating qualities are enhanced in fluids where the overall solids content – particularly the management of drilled solids – is maintained at optimum levels. EvoLube G is particularly effective when used in systems formulated with low clay content or in clay-free formulations, such as the Evolution water-based drilling fluid system. EvoLube G is PDC bit compatible..

Treatment Recommendation

EvoLube G is added directly to the fluid system in concentrations of 0.5-6.0% by volume to achieve desired lubricity. Additions of EvoVis can further enhance results.
