Embodiments of an invention disclosed herein relate to methods for performing formation evaluation of a formation or formation's surrounding to identify and characterize the abundance and morphology of non-ionic conductor grains, 'c-grains', within the formations that are evaluated by formation evaluation (FE) tools. The methods and related systems as disclosed herein are directed to correcting any existing FE logs that can be adversely affected by the presence of c-grains in the detection volume of FE tools, and/or obtaining new FE information that is unavailable by the application of existing FE methods.

Methods for performing formation evaluation and related systems

The present disclosure relates to a porous liquid or a porous liquid enzyme that includes a high surface area solid and a liquid film substantially covering the high surface area solid. The porous liquid or porous liquid enzyme may be contacted with a fluid that is immiscible with the liquid film such that a liquid-fluid interface is formed. The liquid film may facilitate mass transfer of a substance or substrate across the liquid-fluid interface. The present disclosure also provides methods of performing liquid-based extractions and enzymatic reactions utilizing the porous liquid or porous liquid enzyme of the present disclosure.

Porous liquid and methods of making and using the same

For method of utilizing a nondestructive evaluation method to inspect a steel material comprising at least one hysteretic ferromagnetic material and/or at least one nonhysteretic material to identify one or more material conditions and/or one or more inhomogeneities in steel material, the method can comprise the steps of: interrogating the hysteretic ferromagnetic material and/or the nonhysteretic material with an input time varying magnetic field; scanning the steel material and detecting a magnetic response and/or acoustic response over time from the hysteretic ferromagnetic material and/or the nonhysteretic material; determining a time dependent nonlinear characteristic of the received magnetic response and/or acoustic response; and correlating the time dependent nonlinear characteristic of the received magnetic response and/or acoustic response to the one or more material conditions and/or one or more inhomogeneities in steel material.

Methods of using nondestructive material inspection systems

A method for determining one or more material conditions of a hysteretic ferromagnetic material and/or a nonhysteretic material can include interrogating the hysteretic ferromagnetic material and/or the nonhysteretic material with an input time varying magnetic field and detecting a magnetic response and/or acoustic response over time from the hysteretic ferromagnetic material and/or the nonhysteretic material. The method can also include determining a time dependent nonlinear characteristic of the received magnetic response and/or acoustic response and correlating the time dependent nonlinear characteristic of the received magnetic response or acoustic response to one or more material conditions of the material.

Methods and systems for nondestructive material inspection

Methods of determining a spatial distribution of an injected tracer material within a subterranean formation are disclosed, including flowing the tracer material, which includes a tracer electrical capacitance that differs from a formation electrical capacitance of a region of the subterranean formation, into the region of the subterranean formation via a wellbore. Subsequent to the flowing, the methods also include providing an input electromagnetic signal to the region of the subterranean formation. Responsive to the providing, the methods further include receiving an output electromagnetic signal from the subterranean formation. The methods further include determining the spatial distribution of the tracer material within the subterranean formation based, at least in part, on the output electromagnetic signal.

Methods of determining a spatial distribution of an injected tracer material within a subterranean formation

Systems and methods are provided for a magneto-seismic exploration of a subsurface region. An electromagnetic source may transmit time-varying electromagnetic field into the subsurface region, in the presence of a static or time-varying magnetic field, such that a component of the electric field associated with the time-varying electromagnetic field is substantially parallel to an interface between two subsurface formations in the subsurface region, wherein the electric field interacts with the static or time-varying magnetic field and creates a Lorentz force in each of the subsurface formations. One or more seismic receivers may detect a seismic signal generated by a Lorentz force change at the interface between the two subsurface formations. A computer system may be programmed to process and present the detected seismic signal.
