Abstract: A porous electrospun polymeric nanofiber liquid filtration medium, such as an electrospun mats, used for the removal of viral particles (e.g., parvovirus) and other particles in the 18 nm to 30 nm size range from fluid streams, having a mean flow bubble point measured with perfluorohexane above 100 psi. The electrospun medium includes nanofibers having an average fiber diameter of about 6 nm to about 13 nm, and the nanofiber liquid filtration medium has a mean pore size ranging from about 0.01 ?m to about 0.03 ?m, a porosity ranging from about 80% to about 95%, a thickness ranging from about 1 ?m to about 100 ?m, and a liquid permeability greater than about 10 LMH/psi. The high porosity of the electrospun mats enable much higher water fluxes, thus reducing the time required to complete virus filtration steps on a fluid stream.

Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for controlling a hydraulic fracturing job. Diagnostics data of a hydraulic fracturing completion of a wellbore can be received. A fracture formation model that models formation characteristics of fractures formed through the wellbore into a formation surrounding the wellbore during the hydraulic fracturing completion with respect to surface variables can be accessed. A subsurface objective function of fracture complexity can be selected from a plurality of subsurface objective functions for changing one or more of the formation characteristics of the fractures. The fracture formation model can be applied based on the diagnostics data to determine values of the surface variables for controlling the formation characteristics of the fractures to converge on the subsurface objective function of fracture complexity. As follows, a fracture completion plan can be formed based on the values of the surface variables.

The methods of the present disclosure include providing a treatment fluid; introducing the treatment fluid into a wellbore penetrating at least a first portion of a subterranean formation at or above a pressure sufficient to create or enhance one or more formation entry points in the subterranean formation; measuring one or more properties of the treatment fluid or downhole conditions within the subterranean formation; creating a treatment plan substantially in real-time including one or more plans selected from the group consisting of: a proppant placement plan, a fluid placement plan, a completion plan, and any combination thereof, wherein the treatment plan is based at least partially on the one or more properties of the treatment fluid or downhole conditions; and treating at least the first portion of the subterranean formation in accordance with the treatment plan.

Abstract: Aspects of the subject technology relate to systems and methods for controlling a hydraulic fracturing job. A fracturing completion model can be applied to identify a plurality of possible fracturing completion plans for completing one or more wellbores at a target completion. The plurality of possible fracturing completion plans can include varying values of fracturing completion parameters and/or reservoir parameters. Completion characteristic data of the one or more wellbores can be gathered in response to application of at least a portion of a fracturing completion plan of the possible fracturing completion plans. Further, the completion characteristic data can be used to determine whether to apply a different fracturing completion plan of the possible fracturing completion plans. In turn, if it is determined to apply the different fracturing completion plan, then the method can include facilitating switching to the different fracturing completion plan in completing the one or more wellbores.

Abstract: A computing system receives clinical data for a patient that is to undergo treatment for a medical problem and a pre-treatment score value that is indicative of a condition of the patient prior to undergoing the treatment. The computing system provides values in the clinical data and the pre-treatment score value as input to a computer-implemented model. The computer-implemented model outputs, based upon the input, a predicted difference value that is indicative of a predicted change in the condition of the patient from a first point in time occurring prior to the patient undergoing the treatment to a second point in time occurring subsequent to the patient undergoing the treatment. The computing system generates a predicted post-treatment score value for the patient based upon the pre-treatment score value and the predicted difference value, and causes the predicted post-treatment score value to be presented on a display.

Abstract: Evaluating surfactants for use in downhole applications, especially surfactants with similar surface tension or interfacial tension values and wetting properties, may be achieved with a sensitive column test using a non-uniform particulate media therein. An exemplary method may include providing a column containing two types of particles that differ by at least one of: a mean particle diameter, a sphericity, and a chemical composition. Surfactant samples may be individually tested by passing the sample through the column followed by a displacement fluid, typically an oleaginous. The displacement rate and volume of the surfactant sample may be used to assess the surfactant's suitability for downhole applications.

Abstract: A fracturing fluid comprises an aqueous base fluid and a cationic polymer combined with a salt. The fracturing fluid may be used to fracture a subterranean formation. The cationic polymer in combination with a salt provides for reduced clay swelling, while maintaining the granularity and porosity of the formation, which thereby promotes the flow of hydrocarbons from the formation.
