    Abstract: Methods of preventing or minimizing communication between adjacent wells are described. The methods include providing a pre-pad fluid, pad fluid, and/or slurry including a material, introducing the pre-pad fluid, pad fluid, and/or slurry and material into a first well adjacent a second well, allowing the material to block fractures in the first well to prevent or minimize communication between the first well and the second well, stimulating the second well after blocking the fractures, and recovering a formation fluid from the first well, the second well, or both. The material includes one or more of a conformance chemical, diverting agent, or a combination thereof.

    Abstract: Methods and systems for optimizing wellbore completion and, in particular, methods and systems for optimizing hydraulic fracturing parameters are disclosed. In some embodiments, a method of optimizing wellbore completion includes gathering wellbore data, screening and processing the gathered wellbore data, utilizing the screened and processed wellbore data to define an optimized model, and utilizing the optimized model to evaluate combinations of available wellbore completion parameters. In some instances, the optimized model is defined using artificial neural networks, genetic algorithms, and/or boosted regression trees. Further, in some embodiments the combinations of available wellbore completion parameters include hydraulic fracturing parameters, such as number of fractures, fracturing fluid type, proppant type, fracturing volume, and/or other parameters.

    Abstract: Methods are provided for identifying the location and height of induced subterranean formation fractures and the presence of any associated frac-pack or gravel pack material in the vicinity of the borehole using pulsed neutron capture (PNC) logging tools. The proppant/sand used in the fracturing and packing processes is tagged with a thermal neutron absorbing material. When proppant is present, increases in detected PNC formation and/or borehole component cross-sections, combined with decreases in measured count rates, are used to determine the location of the formation fractures and the presence and percent fill of pack material in the borehole region. Changes in measured formation cross-sections relative to changes in other PNC parameters provide a relative indication of the proppant in fractures compared to that in the borehole region

    Abstract: Foundry media having a low surface porosity and methods for producing the media are disclosed. One method includes minimizing a moisture content of the media prior to sintering the media, which minimized moisture content minimized the surface porosity of the sintered media. The media can be coated with resin, and a mold made therefrom. The media requires less resin than conventional media because of the low porosity, and stronger molds can be made from the media.
