Abstract: A drilling fluid composition which includes a base fluid, one or more additives, and a viscosifier package. The base fluid is an invert emulsion comprising oil and water. Further, the one or more additives is chosen from an emulsifier, a weighting material, a fluid-loss control additive, or an alkaline compound. The viscosifier package includes a fatty acid having 6 or more carbon atoms and an aliphatic polyester. The drilling fluid composition has a yield point of from 30 lbf/100 ft2 to 100 lbf/100 ft2 and a low shear yield point of from 10 lbf/100 ft2 to 40 lbf/100 ft2. The associated method of drilling a subterranean well including operating a drill in a wellbore in the presence of the drilling fluid composition is also provided.

Abstract: Drilling fluids and methods of making and using drilling fluids are provided. The drilling fluid contains an aqueous phase, an oleaginous phase, and at least one surfactant having the formula R—(OC2H4)x—OH, where R is a hydrocarbyl group having from 8 to 20 carbon atoms and x is an integer from 1 to 10. Methods of producing drilling fluids include mixing an aqueous phase, an oleaginous phase, and at least one surfactant, and shearing the mixture. Methods of using drilling fluids to drill subterranean formations include mixing an aqueous phase, an oleaginous phase, and at least one surfactant to produce a mixture, which is sheared to form a drilling fluid, and pumped through a drill string in a drill bit located in a subterranean formation. Rock cuttings are transported from the drill bit to a surface of the subterranean formation and the drilling fluid is circulated in the subterranean formation.

Abstract: Cement slurries, cured cements, and methods of making cured cement and methods of using cement slurries are provided. The cement slurries have, among other attributes, improved rheology, such as improved flowability and pumpability and may be used, for instance, in the oil and gas drilling industry. The cement slurry contains water, a cement precursor material and a surfactant having the formula R—(OC2H4)x—OH where R is a hydrocarbyl group comprising from 10 to 20 carbon atoms and x is an integer from 1 and 10. The cured cement have improved strength and density properties due to reduced fluid loss and even placement during curing. The cured cement contains a surfactant having the formula R—(OC2H4)x—OH where R is a hydrocarbyl group comprising from 10 to 20 carbon atoms and x is an integer from 1 and 10.

Abstract: A loss circulation material (LCM) includes an alkaline nanosilica dispersion and a formate activator. The formate activator may be present in an amount in a range of 1 wt % to 40 wt % of the loss circulation material. A method of controlling loss circulation in a loss circulation zone (LCZ) in a wellbore includes introducing an alkaline nanosilica dispersion into the wellbore, introducing a formate activator solution into the wellbore, contacting the alkaline nanosilica dispersion with the formate activator, thereby forming a LCM composition, and forming a gelled solid from the LCM in the loss circulation zone. A method of controlling loss circulation in a LCZ in a wellbore includes introducing a LCM that includes an alkaline nanosilica dispersion and a formate activator into the wellbore such that they contact the LCZ, and forming a gelled solid from the LCM in the LCZ.

Abstract: A tool for use in a wellbore includes an annular body having an inner flow passage extending axially therethrough, at least one gripping member positioned around an outer perimeter of a retainer section of the annular body, and a gate member positioned in the inner flow passage. When the gate member is in a closed configuration, an upstream portion of the inner flow passage is sealed from a downstream portion of the inner flow passage by the gate member. When the gate member is in an open configuration, the upstream portion of the inner flow passage is fluidly connected to the downstream portion of the inner flow passage. At least one static mixing blade extends through the downstream portion of the inner flow passage to mix fluid when it flows through the open gate member.
