Abstract: Described herein is a corrosion inhibitor for use in an aqueous brine solution; the brine solution may be a drilling fluid or refrigeration fluid. The corrosion inhibitor comprises a reducing sugar, such as a monosaccharide, a disaccharide, a polysaccharide, or any combination thereof. A method of drilling a borehole is also described; the method comprises injecting a drilling fluid into the borehole, wherein the drilling fluid comprises an aqueous brine solution comprising a reducing sugar as a corrosion inhibitor.

Abstract: Described herein is a water-based drilling fluid comprising a high concentration of one or more soluble salts and a high concentration of one or more non-reducing sugar alcohols. The described drilling fluid has a lower environmental footprint than the conventional brine-based drilling fluids or oil-based drilling muds. A method of using the drilling fluid is also disclosed; the method comprises injecting a water-based drilling fluid comprising a high concentration of one or more soluble salts and a high concentration of one or more non-reducing sugar alcohols into a borehole.

Abstract: Described herein are deep eutectic solvents and their use as drilling fluids. The DBS typically comprises an organic salt and a metal salt; an organic salt and a hydrated metal salt; an organic salt and a hydrogen bond donor; and/or a metal salt and a hydrogen bond donor. Uses for the DESs and methods of use as drilling fluids are also described.

Abstract: Described herein are ternary deep eutectic solvents and their use as drilling fluids. The TDES typically comprises an organic salt and a metal salt; an organic salt and a hydrated metal salt; an organic salt and a hydrogen bond donor; and/or a metal salt and a hydrogen bond donor, each of which are accompanied by a third moiety. Uses for the TDESs and methods of use as drilling fluids are also described.

Abstract: An anti-accretion drilling fluid additive comprising at least one of a hydrophobically modified natural polysaccharide and hydrophobically modified and chemically derivatized polysaccharide; and whereby said additive acts as a bitumen encapsulant to provide a barrier against bitumen accretion during drilling in steam assisted gravity drainage (SAG) operations.

Abstract: An oil and gas reservoir treatment solution composition comprises an amino acid hydrochloride or esterified amino acid hydrochloride. The treatment fluid composition can be used to remove the formation damage or the filter cake after the drilling operation. The treatment fluid may also be used as part or all of a spearhead, preflush, spacer, post flush, matrix acidizing and fracture acidizing solution where a low pH solution can remove deposits otherwise harmful to the production of oil and gas operation.

Abstract: Fluids for use within a wellbore are provided, comprising amorphous polyalphaolefins (APAO), copolymers of alphaolefins and styrene (APAO-S), terpolymers of alphaolefins and styrene and butadiene (APAO-SB) and/or amorphous polyisobutylene (APIB) and copolymers of polyisobutylene and styrene (APIB-S) and terpolymers of polyisobutylene and styrene and butadiene (APIB-SB) in an oil-based hydrocarbon solvent. Novel properties of such fluids are described, and the fluids may be used, for example, during drilling or fracturing operations.
