  • Patent number: 10781646
    Abstract: A wellbore cleaning system provides a relockable shearing swivel tool that can be used in tandem with a lockable weight set circulation tool. Suspended from an upper drill string is an assembly consisting of a landing sub, the lockable weight set circulation tool and relockable shearing swivel tool are located immediately above a liner top and from which is suspended a lower drills string. The lower drill string and production liner are both significantly smaller in diameter than the upper drill string and production casing such than when fluid is pumped at high rates through the entire drill string and reduced cross sectional area of the lower drills string and production liner causes a large pressure drop characterized at surface by a high pump pressure. As part of the method, an operator makes up a drill string assembly that includes an upper drill string, a lower drill string, a landing sub or device, the lockable weight set circulation tool, and the relockable shearing swivel tool.

  • Patent number: 10774625
    Abstract: A main bore is drilled with an inclined section extending toward a hydrocarbon bearing earth formation. First and second laterals are drilled from the inclined section downward into the formation at a steeper angles than the inclined section. The first lateral is opened to the formation at a depth greater than a depth of an opening of the second lateral. After completion, well fluid flows through the openings in the first and second laterals into the inclined section of the main bore. In response to an increasing water content in the well fluid flowing up the main bore, the flow of well fluid from the first lateral is restricted.

  • Patent number: 10774627
    Abstract: A well has a wellbore extending from a surface. Tubing extends within the wellbore for supporting a downhole pump. Sucker rods extend within the tubing for reciprocating a travelling valve. A load calculator determines loading on the sucker rods during a pump cycle. A variable speed driver reciprocates the sucker rods and travelling valve. A real time speed controller varies a speed of the driver in response to loading information from the load calculator for smoothing the rod load in a beam pump cycle. A target rod load is obtained and a surface linear speed of rods is varied by either slowing or speeding a driver for varying a surface linear speed of the rods when rod loading is above or below the target rod load.

  • Patent number: 10774637
    Abstract: Systems and methods are disclosed that provide highly accurate and controllable measurements of rock formation properties in a wellbore. The systems and methods utilize a prescribed input signal to mechanically perturb a drill string in contact with a rock formation in order to elicit a mechanical response. Based on the input signal and the mechanical response, a transfer function is computed and analyzed, wherein the analysis uses estimates of the drill string resonances to identify rock formation resonances, which are used, in turn, to determine the rock formation properties.
