METHODS AND COMPOSITIONS FOR LOW SALINITY ENHANCED OIL RECOVERY
A method of assessing the response of a reservoir rock to low salinity water includes obtaining a formation core sample of a reservoir rock from a reservoir. In addition, the method includes sequentially washing the formation core sample with a first series of solvents to form a first series of solvent extracts and an extracted formation core sample. Further, the method includes sequentially washing the extracted formation core sample with a second series of solvents to form a second series of solvent extracts and a cleaned formation core sample. The method also includes generating a series of mass spectra of the second series of solvent extracts. The relative abundance of the catecholamine-type structures (CTS) is determined using the series of mass spectra. Still further, the method includes subjecting the formation core sample to analysis by X-ray diffraction to generate a diffraction pattern. The relative abundance of kalonite is determined using the diffraction pattern. Moreover, the method includes assessing a response of the reservoir rock to low salinity water based on the percentage of kalonite and the relative abundance of CTS.
PRESSURIZED RESERVOIR CORE SAMPLE TRANSFER TOOL SYSTEM
A method of transferring at least one subterranean core sample from a retrieval vessel to a testing vessel can include removing at least one pressure barrier on the retrieval vessel using a linear actuator while maintaining a sampling pressure on the at least one subterranean core sample at which the at least one subterranean core sample is taken from a subterranean formation. The method can also include pressurizing the testing vessel to the sampling pressure using the linear actuator, and transferring the at least one subterranean core sample from the retrieval vessel to the testing vessel. The method can further include sealing the testing vessel with the at least one subterranean core sample at the sampling pressure, where the testing vessel allows the at least one subterranean core sample to be tested while the at least one subterranean core sample is maintained at the sampling pressure.

ERGONOMIC CORE DRILLING SYSTEM SHOE INTERFACE
A shoe assembly of a core drilling system includes a lower tubular body threaded onto an upper shoe component, the shoe assembly in turn removably threaded on to an annular inner pipe integral to the earth core drilling system, the lower shoe having a torque pattern of two or more surface indentations or slots disposed strategically about the outer periphery thereof, the torque pattern matching a pattern of protrusive elements on a friction-breaking socket tool, wherein a worker may place the friction-breaking socket tool on or over the lower tubular body and use that tool to break the threaded interface between the upper shoe component and the inner pipe of the core drilling system and unscrew the shoe assembly from the inner pipe to remove an earth core sample from the inner tube pipe and to screw the shoe assembly back on to the inner tube pipe.
ERGONOMIC SHOE INTERFACE SYSTEM FOR CORE DRILLING
A shoe interface system and related methods are provided, where the shoe has a threaded connection to another tubular component of an inner tube assembly used in earth core drilling systems. The shoe interface system comprises a shoe and a tool used to connect and disconnect the shoe from said other tubular component by way of applying a complementary coupling interface that contributes to, or enhances the overall coupling pattern used to create sufficient engagement between contacting surfaces of the shoe and tool, and thus enable the connection and disconnection of the shoe when the tool is in use to break or create a friction lock at the threaded connection. Each complementary coupling interface comprises one or more pairings of raised and depressed surfaces that can be aligned and fitted with one another as a means to make the operation of the tool more ergonomic for the user.
