Viscous aqueous injections fluids including polymers having hydrophilic moieties and hydrophobic groups and at least one of crude oil emulsions and amphiphilic diblock copolymers are provided herein. Methods of making the aqueous injection fluids, and methods of using the aqueous injection fluids for oil recovery are also provided.

Injection fluids for oil recovery and methods of making and using the same

A method for selective extraction of naphthenic acids from an acidic crude oil, including: providing an acidic crude oil including naphthenic acids and having a total acid number (TAN) greater than 0.4; mixing the acidic crude oil with a first aqueous solution including water and a weak base to extract a portion of naphthenic acids from the acidic crude oil thereby creating a second aqueous solution containing a mixture of the portion of naphthenic acids, the water and the weak base in an emulsion; separating the second aqueous solution from the emulsion; wherein the second aqueous solution contains an additional portion of the acidic crude oil; adding a salt to the second aqueous solution, thereby causing the additional portion of the acidic crude oil to separate from the second aqueous solution; removing the additional portion of the acidic crude oil from the second aqueous solution; and extracting the portion of the naphthenic acids from the second aqueous solution.

Method for selective extraction of surfactants from crude oil

A petroleum desalting process in which the role played by the oil/bulk-resolved-water interface in the dehydration of the stabilized emulsion which forms in the desalter is recognized. The desalting process is improved by introducing the demulsifier and chemical high voltage electrodes. Water droplets in the mixture coalesce and settle towards the bottom of the vessel. A stabilized emulsion layer formed from the oil and the water with additives into the water phase and/or injecting chemical additives directly in the vicinity of the water/oil interface. This improved methodology that makes the rapid and effective delivery of chemical demulsifiers to the rag layer and/or oil/bulk-resolved-water interface possible. In operation, the desalting is carried out by mixing a crude oil to be desalted with water and passing the mixture of oil and water to the desalter vessel. The mixture enters the desalting vessel in the form of an emulsified mixture which is then separated by application of an electric field between emulsion-stabilizing solids from the oil forms above the interface between the denser water layer and the supernatant oil layer. A chemical demulsifier is added to the water layer in the region of the stabilized emulsion layer and/or directly into the emulsion layer itself. The separated water is removed as effluent through a water outlet at the bottom of the vessel and desalted oil is removed from the oil layer through an oil outlet at the top of the vessel.

A method for detecting hydrocarbons is described. The method includes performing a remote sensing survey of a survey location to identify a target location. Then, an underwater vehicle (UV) is deployed into a body of water and directed to the target location. The UV collects measurement data within the body of water at the target location, which is then analyzed to determine whether hydrocarbons are present at the target location.

Exploration method and system for detection of hydrocarbons

A method for detecting hydrocarbons with an underwater vehicle equipped with one or more measurement components is described. The method includes navigating the UV within the body of water; monitoring the body of water with measurement components associated with the UV to collect measurement data. The collected data from the UV is used to determine whether hydrocarbons are present and at the location.

Embodiments of the present invention generally relate to microporous membrane, methods for making microporous membrane, and the use of microporous membrane as battery separator film. More particularly, the invention relates to a microporous polymeric membrane including a paraxylylene polymer or copolymer, particularly in combination with a polymeric microporous membrane. The paraxylylene polymer or copolymer can be formed on or laminated to the microporous polymeric membrane.
