Systems and methods for assessing flowability of a multiphase fluid are provided. The method includes agitating a sample of the multiphase fluid contained in a container while controlling an agitation force applied to the sample; pouring the sample, after it has been agitated, into a viscosity cup having an opening at its upper end and an orifice at its lower end and thereby causing the multiphase fluid to flow out of the viscosity cup through the orifice; weighing an amount of the multiphase fluid that has flowed through the orifice and into a receiving vessel over a period of time; and assessing flowability of the multiphase fluid sample using the weight of the multiphase fluid sample in the receiving vessel as a function of time.

Flowability testing systems and methods

Ether amine additives are used in oil recovery such as steam-assisted gravity drainage and cyclic steam stimulation, as well as surface mining of bitumen. Methods of oil recovery using the ether amine additives are described. The ether amine additives are injected with steam into a subterranean oil reservoir such as oil tar sands to improve recovery of oils such as bitumen and/or heavy oil, or used to wash surface-mined rock to assist in oil extraction therefrom. The ether amine additives may be added to steam in steam-assisted oil recovery methods such as cyclic steam stimulation and steam-assisted gravity drainage. Condensates of the additives in steam exhibit very low advancing and receding contact angles and low interfacial tensions at low concentrations of the additives.

Additives for steam-injection oil recovery

The present invention generally relates to methods for enhancing production and transportation of heavy and extra-heavy crude oil and for reducing the growth of asphaltene flocculants or hindering their formation, the methods comprising contacting an oil-soluble composition that comprises polyetheramines, tallow amines, tallow diamines, alkylphenol-formaldehyde resins, reaction products of alpha-olefin, maleic anhydride and pentaerythritol, or a combination thereof, with the heavy or extra-heavy crude oil.
