ORGANIC ACID-BASED ENHANCED WATERFLOODING
In an embodiment, a hydrocarbon recovery material includes an organic acid and a water material, the organic acid including a naphthenic acid, L-proline, or combinations thereof. In another embodiment, an oil recovery method includes injecting a treatment fluid into a reservoir under reservoir conditions, the reservoir containing hydrocarbons, and the treatment fluid includes an organic acid and a water material. In another embodiment, an oil recovery method includes injecting a treatment fluid into a reservoir containing hydrocarbons, the treatment fluid comprising an organic acid in one or more of an oil-in-water emulsion, a resin dispersion, or a polymer capsule.
2-DIMETHYLAMINOETHYL ACRYLATE POLYMERS AND THEIR PREPARATION METHOD
The present invention relates to a water-soluble polymer obtained by polymerization of at least a 2-dimethylaminoethyl acrylate monomer and/or its salts, in presence of at least a tocopherol and/or its derivatives, or a tocotrienol and/or its derivatives, and its uses.
Method of Removing Non-Aqueous Drilling Mud with Banana Containing Fluid
Non-aqueous drilling fluids may be removed from a wellbore or tubing nor casing within the wellbore by introducing into the well a biodegradable aqueous fluid comprising banana.
