The present invention generally relates to a paraffin removal formulation. More specifically the present invention describes the use of glycerol ketals and/or acetals for removing paraffin deposits in oilfield equipment.
摘要:
A method for screening a candidate for efficacy as an asphaltene stabilizer comprises: forming a reconstituted oil by dispersing an asphaltene-containing solid in a hydrocarbon fluid; adding an asphaltene stabilizer candidate to the reconstituted oil to give an additized oil; and analyzing the stability of the asphaltenes in the additized oil. The method may be used to select a candidate for use as an asphaltene stabilizer during crude oil production, transportation or processing.

Methods for servicing a hydrocarbon well using natural gas are provided. The method can include preparing a working fluid comprising about 5 vol% to about 100 vol% of natural gas. A quantity of the natural gas in the working fluid can be sufficient to form a heterogeneous phase well servicing mixture of a gaseous phase natural gas and a solid or liquid phase recovery target material under specified well intervention conditions. During the well servicing operation and under the specified well intervention conditions, the working fluid can be injected into the well and mixing the working fluid with the recovery target material in the well to form the heterogeneous phase well servicing mixture. The natural gas can be in a gas phase and can serve as a carrier fluid for the recovery target material. At least a portion of the heterogeneous phase well servicing mixture can be recovered at surface.
摘要:
The invention relates to a surfactant mixture M comprising at least two different sulfosuccinates S1 and S2, and an additional surfactant S3 selected from the group consisting of alkoxylated aliphatic alcohols, and to a method of treating a hydrocarbon oil containing formation by injection of solutions comprising mixtures of these surfactants.
摘要:
A wellbore fluid treatment may include a compound formed from reaction between cyclic anyhydride pendant groups on a polymer backbone with at least one amino acid, neutralized with a nitrogen containing compound. Methods may include injecting such a compound into a hydrogen production stream. Other methods may include reacting polybutadiene grafted maleic anhydride with at least one amino acid to produce an intermediate; and reacting the intermediate with an amide, amine, or imidazoline having at least a C4-C24 group to produce a compound.
摘要:
The invention relates to a surfactant composition comprising an ionic liquid prepared from an unsubsituted or substituted primary, secondary or tertiary amine, or from an unsubstituted or substituted pyridine, amidine or guanidine with at least one fatty acid and/or resin acid. The invention also relates to a method for treating bitumen froth from a separation process, where bitumen is separated from mineral solids. The method comprises addition of said surfactant composition to the diluent and/or to the froth before phase separation.
摘要:
A composition suitable for addition to frack water comprising: a blend of Bacillus species, 5.6mM β-D-glucose, 5.6mM β-fructose, 30mM L-asparagine and 6 mM KCl in 50mM-Tris / HCl buffer, pH 7.5 (GFAK); wherein on germination the bacteria produce prodigious amounts of the natural biosurfactant surfactin, biocidal concentrations of subtilin and lanthionine-containing peptide antibiotics which act to competitively exclude unwanted bacteria; in addition they produce α-amylase enzymes which detach biofilm exopolysaccharide components; when added to fracking fluids they increase efficiency, control biofilm formation and reduce or remove the need to add environmentally-damaging chemicals to frack fluids.
摘要:
Proppant compositions and methods for using same are disclosed herein. In particular, a proppant composition for use in hydraulic fracturing is disclosed herein. The proppant composition can contain a plurality of particulates and at least one particulate of the plurality of particulates containing a chemical treatment agent. The at least one particulate having a long term permeability measured in accordance with ISO 13503-5 at 7,500 psi of at least about 10 D. The at least one chemical treatment agent can separate from the at least one particulate when located inside a fracture of a subterranean formation after a period of time.
