  • Publication number: 20190256759
    Abstract: A combination of three polymers including a crosslinked acrylamide-TBAS copolymers in inverse emulsion form, N-vinyl pyrrolidone-acrylamide-TBAS terpolymer, and crosslinked N-vinyl pyrrolidone-acrylamide-TBAS acts as high temperature, high pressure fluid loss control additives for water-based drilling fluids systems. The combination is particularly useful for high salt, high density drilling fluids, and high temperature applications.

  • Publication number: 20190258639
    Abstract: A tool for combining common processes shared by at least two or more sub-queries within a query is provided. The tool determines whether one or more sub set relationships are shared between the at least two or more sub-queries. Responsive to a determination that one or more sub set relationships are shared between the at least two or more sub-queries, the tool determines an order class for the at least two or more sub-queries based on the one or more sub set relationships, wherein determining the order class includes transforming the query to include one or more differing aspects within the single shared common process, with the one or more differing aspects arranged based, at least in part, on a query style, a query type, and a query function. Responsive to determining an access path for the query, the tool executes the access path during run-time for data accessing.

  • Patent number: 10176000
    Abstract: A method for providing application assistants on applications is provided. The method may include performing pattern analyses on the applications, wherein application features are collected. The method may include determining application pattern types based on the pattern analyses. The method may include determining whether user customizations associated with the determined application pattern types are received. The method may include in response to the determination that user customizations are not received, associating the determined application pattern types with the applications, and generating application assistants based on the associated determined application pattern types. The method may include in response to the determination that user customizations are received, associating the user customizations with the applications, and generating application assistants based on the associated user customizations.

  • Publication number: 20180322126
    Abstract: Embodiments of the present invention provide efficient systems and methods for searching a keyword. Embodiments of the present invention can be used to more quickly and comprehensively search a document for a keyword or phrase, based on the preferences and behaviors of a user, so that the returned results to the user are ranked in order of the preferences of the user. By factoring in user data such as time spent on certain content and highlighted content, the system is able to more efficiently return preferred results of a user of a keyword search.
