摘要： A composition that includes a fluorescent metal-organic framework (MOF) and a drilling fluid is provided. The MOF includes a porous, crystalline structure and a fluorescent source. A method includes introducing a MOF into a drilling fluid and circulating the drilling fluid through a well during a drilling operation that creates formation cuttings such that the fluorescent MOF interacts with the formation cuttings, creating tagged cuttings. The method further includes collecting returned cuttings from the circulating drilling fluid at a surface of the well, detecting the presence of the fluorescent MOF on the returned cuttings to identify the tagged cuttings, and correlating the tagged cuttings with a drill depth in the well at a time during the drilling operation.

摘要： Embodiments of the disclosure include compositions and methods that stabilize a injection fluid when exposed to reservoir conditions, reducing formation damage and increasing the amount of hydrocarbon recovered. Specifically, the formulation is a single-phase liquid surfactant package which comprises a non-ionic surfactant and optionally one or more secondary surfactants.

摘要： Compositions for stimulating a subterranean formation may include 10 wt % to 25 wt % of an oleaginous liquid; 5 wt % to 50 wt % of a fatty alkyl alcohol ethoxylate; 15 wt % to 75 wt % of at least one of a fatty alkyl ethoxylated ammonium salt, a zwitterionic surfactant, an alkyl ether sulfate salt or an alkyl ether sulfonate salt; and 5 wt % to 40 wt % of a co-solvent, each wt % being based on a total mass of the composition, excluding aqueous fluids. The compositions may be combined with an aqueous fluid, optionally to form foams or emulsions.

摘要： Disclosed herein are compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations (tight shale reservoirs). The flowback compositions include an anionic dimer surfactant, an anionic monomer surfactant, and a demulsifier. The flowback compositions convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations. The flowback composition are useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.

摘要： A method of treating a fluid, which method includes the steps of: (a) contacting a fluid containing at least one sulfide with a sulfide-reducing amount of a composition comprising an lignocellulosic liquor comprising one or more lignin-derived compounds and one or more hemicellulose sugar monomers and/or oligomers and (b) allowing the lignocellulosic liquor to react with at least a portion of the sulfide in the fluid.

摘要： Provided are compositions and methods of using a liquid suspension of hollow particles comprising a plurality of hollow particles, water, a suspending aid, and a stabilizer selected from the group consisting of a non-ionic surfactant, a latex, an oleaginous fluid, porous silica, and combinations thereof. The liquid suspension is homogenous. An example method includes statically storing the liquid suspension in a container for at least one week; wherein the liquid suspension maintains a difference in density from the top of the container to the bottom of the container of less than one pound per gallon while stored. The method further includes adding the liquid suspension to a treatment fluid; wherein the liquid suspension reduces the density of the treatment fluid; and introducing the treatment fluid into a wellbore penetrating a subterranean formation.
