"Sedco Rig #71 has worked primarily in Maidstone, Saskatchewan for the past 3 years drilling heavy oil horizontal wells. My drilling personnel take pride in the speed and efficiency with which we drill, but there is limited amount of time that can be allocated for rig maintenance. The heavy oil stains and cakes onto every part of the rig and we have found that BioSol 310 removes the sludge with relative ease. We've expanded it's use to include engines, mud tanks, shale shakers and so on. Reducing harm to the environment has become an important factor in drilling in the 90's. This product helps us meet and exceed industry standards. Thank you for the introduction to BioSol 310. Our continued use is guaranteed."
