    Abstract: Described herein are various embodiments of computer-implemented methods, computing systems, and program products for analyzing a flood operation on a hydrocarbon reservoir. For example, an embodiment of a computer implemented method of analyzing at least a first flood operation and a second flood operation. The embodiment includes, for each flood operation: receiving production data and injection data, running capacitance resistance modeling, using the generated response times, the generated interwell connectivities, the received production data, the received injection data, or any combination thereof to generate a proxy of pore volume swept per well pair, and aggregating the generated proxies to generate an estimate of pore volume swept at a well level, at a reservoir level, or both for the flood operation. The embodiment also includes comparing the generated estimate of pore volume swept to determine a change in sweep efficiency at the well level, at the reservoir level, or both.

    Abstract: One method as described herein relates to making a high molecular weight, monoesterified polyimide polymer using a small amount of bulky diamine. These high molecular weight, monoesterified polyimide polymers are useful in forming crosslinked polymer membranes with high permeance that are useful for the separation of fluid mixtures. Another method as described herein relates to making the crosslinked membranes from the high molecular weight, monoesterified polyimide polymer containing a small amount of bulky diamine. The small amount of bulky diamine allows for formation of both the high molecular weight polyimide polymer and for covalent ester crosslinks via reaction of the carboxylic acid groups with a diol crosslinking agent. This small amount of bulky diamines reduces chain mobility or segmental motion during crosslinking and reduces large loss of permeance. As such, this method provides a crosslinked membrane with good permeance and selectivity.

    Abstract: Electrical power may be generated by way of electromagnetic induction through oscillating linear translation driven by the flow of a fluid being transported through a tubular structure. In exemplary embodiments, a conductive coil is disposed in a fixed position along a length of a tubular structure such that the conductive coil encircles the tubular structure. A linear translation apparatus is disposed radially inward from the conductive coil and is configured to move linearly parallel to a longitudinal axis of the tubular structure and within the conducting coil by harnessing mechanical energy from fluid flowing within the tubular structure. Magnets are affixed to the linear translation apparatus to cause electrical power to be generated in the conductive coil by way of electromagnetic induction responsive to the magnets passing by the conductive coil when the linear translation apparatus is in motion.
