Abstract: Systems, methods, and storage media for detecting a given subsurface event in a subsurface volume of interest are disclosed. Exemplary implementations may: receive a subsurface fiber optic data set; receive a sensor data set using one or more sensors; constrain the subsurface fiber optic data set based on a given parameter value of a given parameter within a certain range to generate a constrained subsurface fiber optic data set; use sets of models to refine the constrained subsurface fiber optic data set to generate a refined subsurface fiber optic data set; estimate an event location of the given subsurface event based on the refined subsurface fiber optic data set; and estimate an origin time based on the event location.

Abstract: Zeolites having highly dispersed bimetallic clusters, uniformly distributed in size and composition, encapsulated therein are disclosed. Metal encapsulation and alloying is conferred by introducing ligated metal cation precursors into zeolite synthesis gels, which are subsequently crystallized hydrothermally to form zeolites with metal cations occluded in the pores. The ligated cations are anchored to the zeolite framework via siloxane bridges which enforces their uniform dispersion throughout the zeolite crystals. Treatment of the crystallized zeolites in O2 and then H2 forms bimetallic clusters, which remain narrowly distributed in size and composition.

Abstract: One embodiment includes generating a polymer partitioning model that determines a concentration of the polymer in a brine phase of the microemulsion system and a concentration of the polymer in an aqueous component of a microemulsion phase of the microemulsion system. The embodiment includes determining a viscosity of the brine phase of the microemulsion system using the concentration of the polymer in the brine phase of the microemulsion system, determining a viscosity of the aqueous component of the microemulsion phase of the microemulsion system using the concentration of the polymer in the aqueous component of the microemulsion phase of the microemulsion system, and determining a viscosity of the microemulsion phase of the microemulsion system using the viscosity of the aqueous component of the microemulsion phase of the microemulsion system. The embodiment includes using determined viscosities to determine performance of a chemical enhanced oil recovery process scenario.

Abstract: Systems and methods for training a model that uses probabilities of lithologies as prior information in an inversion are disclosed. Exemplary implementations may: obtain training data, the training data including (i) subsurface map data sets, and (ii) known lithologies; obtain an initial seismic mapping model; generate a conditioned seismic mapping model by training the initial seismic mapping model; store the conditioned seismic mapping model; obtain a target subsurface map data set; apply the conditioned seismic mapping model to generate a classified lithology map data set; apply an inversion to the classified lithology map data set to generate volumes of lithologies; generate an image that represents the volumes of lithologies; display the image.

Abstract: A system can include at least one measuring device that captures and collects multiple two-dimensional images of a mooring line disposed in water. The system can also include a mooring line assessment system that includes a controller communicably coupled to the at least one measuring device. The controller can receive the two-dimensional images from the at least one measuring device. The controller can also generate a three-dimensional reconstruction of the mooring line based on the two-dimensional images. The controller can further present the three-dimensional reconstruction to a user. The two-dimensional images can be captured and the recommendation can be made while the mooring line is in situ.

Abstract: A method for treating water high in sulfate includes passing the water at a temperature of 10° C. to 45° C. through a nanofiltration membrane module and a reverse osmosis membrane module in series such that the retentate stream from the nanofiltration membrane module is fed to the reverse osmosis membrane module. A first permeate stream from the nanofiltration membrane module has at least 90% lower sulfate content than the feed stream. A second permeate stream from the reverse osmosis membrane module has at least 95% lower sulfate content than the retentate stream from the nanofiltration membrane module. The first and second permeate streams are combined to form a treated stream containing less than 40 ppm sulfate. A system including the nanofiltration and reverse osmosis membrane modules in series is also disclosed.
