  • Patent number: 11142867
    Abstract: A process of fabricating the waterproof coating may include selecting a textile material substrate, utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate, and optionally coating the substrate with a hydrophobic chemical agent and/or other chemical agents to create a surface with nanoscopic or microscopic features. The process may utilize an all solution process or controlled environment for fabricating a fluorine-free waterproof coating that prevent wetting or staining of a substrate, or may utilize a controlled environment. The composition coatings for treating textile materials improve soil-resistance and stain-resistance of the textile materials while the compositions contain no fluorine-based chemicals. In addition, the composite solution may impart additional properties such as physical strength to the textile whilst retaining the original appearance.

  • Publication number: 20210311218
    Abstract: The present method predicts and separates dispersive surface waves from seismic data using dispersion estimation and is completely data-driven and computer automated and no human intervention is needed. The method is capable of predicting and suppressing surface waves from recorded seismic data without damaging the reflections. Nonlinear signal comparison (NLSC) is used to obtain a high resolution and accurate dispersion. Based on the dispersion, surface waves are predicted from the field recorded seismic data. The predicted surface waves are then subtracted from the original data.

  • Patent number: 11124449
    Abstract: The present disclosure relates to the fabrication and characterization of an optical fiber capable of firing light virtually from any point along its circumferential surface. The optical fiber is preferably prepared by laser micromachining. In preferred embodiments, laser radiation is focused onto a multimode optical fiber axis, forming a conical-shaped cavity (side window) in the fiber core. Because of the total internal reflection when the laser beam reaches the side window-outside medium interface, the beam is reflected to the side of the optical fiber.

  • Patent number: 11125043
    Abstract: Reduced order modeling is used in the present systems and methods for monitoring the health of a system and is particularly useful in monitoring the health and estimating the remaining useful life of blow out preventer (BOP) annular used in an oil or gas well. A reduced order model is a linear low order characterization of the system that describes the annular behavior with a small number of parameters that can be interpreted physically. The reduced order model is then identified and adapted in real-time in order to detect the change in the system behavior and characteristics. This adaptation helps in drawing conclusions on diagnostics and prognostics of the physical system.

  • Patent number: 11078774
    Abstract: The electrical submersible pump (ESP) is currently the fastest growing artificial-lift pumping technology. Deployed across 15 to 20 percent of oil-wells worldwide, ESPs are an efficient and reliable option at high production volumes and greater depths. However, ESP performance is often observed to decline gradually and reach the point of service interruption due to factors like high gas volumes, high temperature, and corrosion. The financial impact of ESP failure is substantial, from both lost production and replacement costs. Therefore, ESP performance in extensively monitored, and numerous workflows exist to suggest actions in case of break-downs. However, such workflows are reactive in nature, i.e., action is taken after tripping or failure. Therefore, a data-driven analytical framework is proposed to advance towards a proactive approach to ESP health monitoring based on predictive analytics to detect impending problems, diagnose their cause, and prescribe preventive action.
