Abstract: 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.

Abstract: A method and apparatus for identifying non-elastic indicators for a subsurface region, the method including obtaining seismic data for the subsurface region; generating a best-fit elastic model from the seismic data; and identifying non-elastic indicators from the seismic data and the best-fit elastic model. The method and apparatus may also include estimating reservoir flow properties from the non-elastic indicators based on a poroelastic interpretation of the seismic response. The method and apparatus may also include subdividing the seismic data into a plurality of subdivisions, wherein: generating the best-fit elastic model from the seismic data includes generating an individual best-fit elastic model for each subdivision; identifying non-elastic indicators from the seismic data and the best-fit elastic model includes identifying individual non-elastic indicators from each subdivision and its respective individual best-fit elastic model; and estimating the reservoir flow properties from the non-elastic indicators comprises analyzing the individual non-elastic indicators based on the subdivisions.

Abstract: A redox flow battery may include: a positive half-cell comprising a catholyte; a negative half-cell comprising an anolyte; and an ion permeable membrane, wherein the ion permeable membrane separates the catholyte and the anolyte, and wherein the catholyte, the anolyte, or both comprise a low-transition temperature material comprising: a redox-active phase; and an ionically conducting organic salt.
