Abstract: One or more embodiments presently described are directed to lubricants and methods for making such lubricants. According to one embodiment, a lubricant suitable for use in a water-based drilling fluid may comprise one or more alkyl esters and a fatty acid blend comprising one or more medium-chain fatty acids. The one or more medium-chain fatty acids may be at least 50 weight percent (wt. %) of the fatty acid blend. The weight ratio of the one or more alkyl esters to the fatty acid blend may be from 1:1 to 3:1.

Abstract: According to one or more embodiments of the present disclosure, water-based drilling fluids may include an aqueous base fluid and one or more additives. In embodiments, water-based drilling fluids may include a lubricant blend including at least oleic acid and palmitoleic acid. The sum of the volume percent of the oleic acid and palmitoleic acid may be from 0.1 vol. % to 10 vol. % of the total volume of the water-based drilling fluid. In embodiments, water-based drilling fluids may include a lesser melting point fraction of jojoba oil in an amount of from 0.1 vol. % to 10 vol. % relative to the total volume of the water-based drilling fluid. At least 90% of the lesser melting point fraction of jojoba oil may have a melting point less than or equal to 15° C. Methods for drilling subterranean wells with the water-based drilling fluids are also disclosed.

Abstract: A rapidly dehydrating fluid (RDF) composition that forms a permeable and decomposable plug and methods of lost circulation control and manufacture of the RDF composition. The RDF composition may include a carrier fluid such as water, a cellulosic microfiber viscosifier, date tree seed particles, and fibers formed from date tree waste such as date tree trunks. The RDF composition may mitigate or prevent lost circulation by forming a decomposable plug in a fracture of the lost circulation zone and may also enable the production of hydrocarbons from the zone without removal of the plug.

Abstract: One or more embodiments presently described are directed to drilling fluid compositions that include lubricants, methods for making the drilling fluids, and methods for drilling subterranean wells utilizing the drilling fluids. According to one embodiment, a drilling fluid composition may include a base fluid including water, a weighting agent in an amount of from 0.1 weight percent (wt. %) to 75 wt. % relative to the total weight of the water-based drilling fluid, and a lubricant in an amount of from 1 wt. % to 10 wt. % relative to the total weight of the water-based drilling fluid. The lubricant may include one or more alkyl esters and a fatty acid blend including one or more medium-chain fatty acids. The one or more medium-chain fatty acids may be at least 50 wt. % of the fatty acid blend.

Abstract: Provided is a lubricant, which may include a mixture of alkyl-esterified fatty acids from waste vegetable oil and a C8/C10 fatty acid blend. The C8/C10 fatty acid blend may include a caprylic fatty acid (C8) and a capric fatty acid (C10). Provided is a method of preparing a lubricant, which may include providing alkyl-esterified fatty acids from waste vegetable oil and a C8/C10 fatty acid blend, and mixing them such that a homogeneous lubricant composition forms. Further provided is a water-based mud, which may include an aqueous base solution and a lubricant composition. Further provided is a method off preparing the water-based mud, which may include providing an aqueous base solution and a lubricant composition and mixing them such that the water-based mud forms. Further provided is a method of using a water-based mud, which may include introducing into a wellbore the water-based mud comprising a lubricant composition.
