Title: Wayne S Stewart: Innovator in Non-Aqueous Fluid Technologies
Introduction
Wayne S Stewart is a notable inventor based in Bartlesville, Oklahoma, with a significant contribution to the field of non-aqueous fluids. He holds a total of six patents, showcasing his innovative approach to solving complex problems in fluid compositions.
Latest Patents
One of Stewart's latest patents focuses on methods of reducing sag in non-aqueous fluids. This invention involves combining a cystol ester compound with a non-aqueous fluid and particles to minimize sag without significantly increasing the viscosity of the fluid composition. The resulting fluid composition includes the non-aqueous fluid, the particles, and the cystol ester compound. Suitable cystol ester compounds consist of cystol ester and its derivatives, which have mono-, di-, or tri-substituted aromatic compounds as substituents. The non-aqueous fluid may contain an invert emulsion, diesel oil, mineral oil, an olefin, an organic ester, a synthetic fluid, or combinations thereof. Additionally, this fluid composition can be utilized as a wellbore servicing fluid, such as a drilling fluid. The particles may include a weighting agent, such as barite, galena, hematite, dolomite, calcite, or combinations thereof. Furthermore, the fluid composition may also incorporate organophilic clay.
Another significant patent by Stewart addresses reducing fluid loss in a drilling fluid. This invention relates to a low toxicity drilling mud oil. In certain embodiments, the fluid loss characteristic of the drilling mud oil used in a borehole can be reduced to less than 0.2 ml/30 minutes by adding about 0.05% to about 2.0% by weight of a butadiene-styrene-butadiene (BSB) block copolymer that contains about 20% by weight or more styrene.
