Abstract: Drilling fluid compositions include a base fluid, at least one additive chosen from an emulsifier, weighting material, fluid-loss additive, viscosifier, or alkali compound, and from 0.1 wt. % to 1 wt. %, based on total weight of the drilling fluid composition, of an ethoxylated alcohol compound having the formula R—(OCH2CH2)7—OH, in which R is a saturated or unsaturated, linear or branched hydrocarbyl group having from 8 to 20 carbon atoms. The base fluid may be an aqueous base fluid. Methods for drilling a subterranean well include operating a drill in a wellbore in the presence of a drilling fluid composition including the base fluid, the additive, and the ethoxylated alcohol compound.

Abstract: A lost circulation material (LCM) having date fruit caps is provided. The date fruit cap LCM includes date fruit caps from a date tree. The date fruit caps have multiple flakes (for example, three flakes) attached at one end to an end cap and free at the other end. The date fruit caps may be obtained from the waste product of date tree and date fruit processing. The date fruit cap LCM may be added to a drilling fluid (for example, a drilling mud) to mitigate or prevent such lost circulation in a well. Methods of lost circulation control with the date fruit cap LCM are also provided.

Abstract: A water-based drilling fluid which includes an aqueous fluid and a water-soluble dissipative surfactant composition is described, wherein the dissipative surfactant composition includes at least one fatty acid or ester derivative of a plant or vegetable oil. Also described are methods of using such aqueous-based drilling fluids including the dissipative surfactant composition as described in hydrocarbon recovery operations associated with oil/tar sand, where such fluids act to increase the dispersant qualities of hydrocarbons within the oil/tar sand, and where such fluid exhibit a reduced coefficient of friction.
