Fish-Friendly Downhole Drilling Lubricant Reduces Need for Oil-Based Mud

Costa Mesa, California, October 11, 2012 – ProOne’s Drilling Fluid has been demonstrated to be “non-hazardous to aquatic life” while it’s high temperature lubricating capabilities in water-based “mud” (WBM) exceeds those of typical oil-based mud (OBM). For drill rig owners, this means not having to sacrifice lubricating and rate of penetration characteristics while significantly reducing drilling costs and environmental risks. Having passed several of the most stringent U.S. (LC50) and Canadian (Microtox D50) test for aquatic safety, ProOne’s Drilling Fluid works with WBM and outperforms OBM in many situations where an OBM is needed but not feasible or permitted.

The LC50 test for aquatic toxicity determines the lethal concentration (LC) of a material at which 50% of the specimens (fish or crustaceans) die when exposed to it for 96 hours. In suspended particulate phase (SSP) testing, ProOne was tested in a water-based mud mixture with a No. 7 drilling fluid. A minimum 30,000ppm is required to pass and the industry prefers 150,000ppm. At a 3% concentration ProOne Drilling Fluid achieved 470,000ppm level, 15 times the margin of safety. At a 5% concentration ProOne achieved a 240,000ppm level, 7 times the margin of safety. During the tests, at all SSP and lubricant concentration, all of the fish specimens survived.

It was further determined that the LC50 rating of the ProOne’s Drilling Fluid is greater than 750mg/L where materials with and LC50 above 500 mg/L are considered “non-hazardous” to aquatic life. In contrast, No. 2 diesel fuel (the primary constituent of oil-based mud) is highly toxic to aquatic life and humans and contains suspected carcinogens.

“Major operators throughout the industry have experienced our drilling lubricant as the product that saves them money and solves problems when the drilling gets tough,” says Tim Wagner, ProOne’s Vice President of Research & Development. “We see the LC50 test results providing huge benefits to drillers since they can have all the environmental advantages of a water-based mud while outperforming oil-based mud with improved penetration characteristics.”
