  • Publication number: 20170275965
    Abstract: A plugging device, well system and method. In one example, a wrap, band or other type of binding is utilized to secure together multiple fibers, tubes, filaments, films, fabrics or lines of the plugging device. In another example, fibers, tubes, filaments, films, fabrics or lines are fused, adhered or bonded to an outer surface of a body of the plugging device. In other examples, a material of the plugging device may become more rigid or swell in a well. A plugging device may comprise a body loosely enclosed in a bag, wrapper or other enclosure.

  • Patent number: 9771776
    Abstract: A valve assembly with a longitudinal flow passage, a first longitudinal section of the flow passage having less flow area than a second longitudinal section of the flow passage, and a valve that permits flow in only one direction through the flow passage, the valve including a closure member. In an open position, the closure member can be disposed between the second flow passage section and a chamber in fluid communication with the first flow passage section. A method in which a valve assembly is connected in a tubular string, the valve assembly including a valve that permits flow in only one direction through a longitudinal flow passage of the valve assembly, and fluid is flowed in the one direction through the tubular string, thereby displacing a closure member of the valve to an open position and preventing displacement of the closure member toward a closed position.

  • Publication number: 20170030169
    Abstract: A method can include deploying a plugging device into a well, the plugging device including a body, and an outer material enveloping the body and having a greater flexibility than a material of the body, and conveying the plugging device by fluid flow into engagement with the opening, the body preventing the plugging device from extruding through the opening, and the outer material blocking the fluid flow between the body and the opening. In another method, the plugging device can include at least two bodies, and a washer element connected between the bodies, the washer element being generally disk-shaped and comprising a hole, a line extending through the hole and connected to the bodies on respective opposite sides of the washer element, the washer element preventing the plugging device from being conveyed through the opening, and the washer element blocking the fluid flow through the opening.

  • Patent number: 9546536
    Abstract: A casing string is augmented with one or more variable flow resistance devices or “vibrating tools” to facilitate advancement of the casing and distribution of the cement in the annulus once the casing is properly positioned. The method includes vibrating the casing string while advancing the casing down the wellbore or while the cement is pumped into the annulus, or both. After the cementing operation is completed, the devices may be drilled out to open the casing string for further operations. The casing string assembly may include a vibrating tool at the end in place of a conventional float shoe or float collar. Multiple vibrating tools can be employed in the casing string, and they may be combined with conventional float shoes and collars. Additionally, vibrating tools in the form of plugs can be pumped down and landed inside the casing string.
