  • Patent number: 9784067
    Abstract: Present embodiments are directed to coupling a cementation assembly with a hung or set liner string in a well and moving the liner string during a cementation operation. Specifically, for example, a process in accordance with present techniques includes running a cementation assembly into a well on drill pipe and engaging, with a distal end of the cementation assembly, a liner top assembly of a liner string that is positioned downhole in the well, wherein the liner string was previously positioned downhole in the well without being cemented into the well. Further, the process includes latching the cementation assembly with the liner string such that movement of the cementation assembly is translated to the liner string, and flowing cement through the drill pipe and into the liner string while moving the cementation assembly and the liner string.

  • Patent number: 9784087
    Abstract: A new method separating sand, solids, and produced particulates down-hole in a well producing hydrocarbons. The separation assembly can include ether one, two, or more segments or stages of varying lengths depending upon the individual application. The assembly is installed into the tubing string or delivery conduit of a well producing hydrocarbons. One stage can consist of a velocity chamber whereby separation of particulates occurs by increasing the downward velocity of particulates and reducing the upward velocity of hydrocarbons thereby allowing the particulates to “fall-out” into a lower chamber where the particulates are captured. Another stage can consist of a filter whereby particulates are captured in a chamber that can consist of filtering materials such as gravel, rock, sand, wood, or manmade materials. Each of the stages can be employed individually or in combination.

  • Patent number: 9784090
    Abstract: The present invention provides a method for selecting the location of a stimulating well, comprising the steps of conducting a geological study of a field containing a geothermal hydrothermal resource by operating geological useful equipment, determining a maximum horizontal stress line within said field by means of a device, generating a map of existing wells including a plurality of sub-commercial wells within said field relative to said maximum horizontal stress line, measuring a distance between each of said sub-commercial wells and the maximum horizontal stress line, determining that those sub-commercial wells aligned with, or located relatively close to the maximum horizontal stress line are stimulatable, and selecting a location of a stimulating well for stimulating the stimulatable well that is separated less than an anticipated fracture propagating distance from said stimulatable well.

  • Patent number: 9777536
    Abstract: A knock-out plug having sections held together by a hinge along the top side. The knock-out plug can bend or fold along a crease in the bottom side when force is applied to the top side, or hinge side, of the plug. Conversely, force applied to the bottom side and peripheral wall of the knock-out plug tends to hold the sections together. When placed into the opening in an HSA, the edge of the opening and force of the soil against the bottom side during drilling keeps the plug in place and the sections intact. When desired, the knock-out plug can be hit or pounded on the top side, through the HSA channel which causes the plug to fold or bend and be released easily from the opening.

  • Patent number: 9719326
    Abstract: Two control systems are provided to run in parallel between a surface location and the final controlled element, in this case a subsurface safety valve. The primary control circuit is controlling until a predetermined signal is given to the secondary control line which has the effect of actuating the valve a single time against the force of a bias or a shear pin that breaks. The movement of a shuttle in the housing due to the predetermined signal being provided in the secondary line puts the secondary control system in the position of running the tool. The primary system is valved off and cannot return into service. There are just two lines into and out of the housing to make the valve operate at the desired location. A test port is provided for surface testing.
