Abstract: Compositions may include an asphaltene dispersant that is the product of a reaction between a polysaccharide having at least two sugar subunits and one or more fatty acid reagents, and a petroleum fluid produced from a subterranean formation and containing asphaltenes therein. The asphaltene dispersant may have a molecular weight of at least 4000 Da. Compositions may further include an aromatic solvent. Methods may include contacting a hydrocarbon fluid with an asphaltene dispersant dissolved in an aromatic solvent, wherein the asphaltene dispersant is the product of the reaction of a polysaccharide and one or more fatty acid reagents. Methods may also include contacting a hydrocarbon fluid with an asphaltene, wherein the asphaltene dispersant is the product of the reaction of a polysaccharide and one or more fatty acid reagents and has a molecular weight of at least 4000 Da.

Abstract: A method for injecting a controlled volume of liquid into a system having at least one liquid injection point includes inputting into a controller pressure measurements made at at least one position from a liquid storage device and the at least one injection point. The controller automatically causes a liquid injector to inject the liquid for a time duration corresponding to a predetermined liquid volume. The time duration is adjusted in relation to the measurements of pressure.

Abstract: An injection fluid is pressurised for injection into a subsea installation or equipment by using a flow of hydrocarbon production fluid to draw the injection fluid from a source and using pressure of the production fluid to pressurise the drawn injection fluid to an elevated pressure. In response to an ejector (26) that is powered by the flow of the production fluid, a pressure booster (28) draws in the injection fluid for pressurisation. A portion of the production fluid is diverted to the pressure booster (28) to pressurise and expel the injection fluid and is then exhausted to the ejector (26) as more injection fluid is drawn in.

Abstract: A system and method for preventing scale in a well. The system includes a conduit providing fluid communication between a first location and a second location and a sensor at the second location configured to measure scale deposition in the fluid and a value of a fluid parameter. A scale deposition at the first location is determined from the scale deposition at the second location and the fluid parameter at the second location. A scale inhibitor is injected at the first location based on the determined scale deposition at the first location.

Abstract: Compositions comprising non-halogenated solvents for use in various aspects of a life cycle of an oil and/or gas well, and related methods, are provided. In some embodiments, the composition comprises a solvent blend and one or more surfactants. In some embodiments, the solvent blend comprises a first type of solvent (e.g., a terpene) and a second type of solvent (e.g., a non-halogenated solvent). The composition may comprise about 90 wt% to 99.9 wt% of the solvent blend, and about 0.1 wt% to 10 wt% of one or more surfactants, versus the total weight of the composition. In some embodiments, compositions can be used in methods for treating an oil and/or gas well, having a wellbore that comprises one or more fluids. A composition may be delivered into the wellbore, passing through the one or more fluids to reduce residues comprising asphaltenes, paraffins or combinations thereof on or near the wellbore.
