  • Publication number: 20190136652
    Abstract: Methods and apparatus are described to drill and complete wellbores. Such wellbores include extended reach horizontal wellbores, for example in shales, deep subsea extended reach wellbores, and multilateral wellbores. Specifically, the invention provides simple threaded subassemblies that are added to existing threaded tubular drilling and completion equipment which are used to dramatically increase the lateral reach using that existing on-site equipment. These subassemblies extract power from downward flowing clean mud, or other fluids, in an annulus to provide additional force or torque on tubular elements within the wellbore, while maintaining circulation, to extend the lateral reach of the drilling equipment and completion equipment. These added elements include combinations of The Leaky Seal™, a Cross-Over, The Force Sub™ and The Torque Sub™. The use of such additional simple elements allow lighter drilling equipment to be used to reach a given lateral distance, therefore reducing drilling costs.

  • Patent number: 10232919
    Abstract: According to one or more embodiments disclosed herein is a method of transporting equipment between sea-surface and seafloor by providing a structure with a subsea equipment package mounted thereon. The structure is used for installation and recovery in a subsea environment by changing the buoyancy of the structure or ballasting the structure to effect a controlled sinking motion.

  • Patent number: 10046907
    Abstract: A liquid storage tank comprising an outer container wherein the outer container is rigid and has at least one inner container disposed within the outer container. The at least one inner container contains at least one stored liquid which may be refilled from a surface vessel or host facility. The at least one inner container is flexible and pressure balanced while the volume of the outer container remains fixed, and the volume of the at least one inner containers is variable. Disposed on the outer container is a balance assembly containing an isolation valve, a check valve, and a flexible bladder. The balance assembly allows for the hydrostatic pressure to be maintained during chemical dosing and tank raising operations.

  • Patent number: 9284780
    Abstract: A drilling apparatus comprised of a multiplicity of subassemblies for drilling an open-hole extension from within an existing cased borehole located in a geological formation for the production of oil and gas. In one embodiment, one subassembly includes a motor located within a cased section of the borehole that rotates a drill pipe segment attached to a rotary drill bit in the open-hole to drill the open-hole extension of the well. In another embodiment, a shroud encloses the motor located within the cased portion of the well that is used to control the mud flow to and from the bit in the open-hole during the drilling process.

  • Patent number: 8876960
    Abstract: A method and system for transporting and processing sour gas are provided. The method includes collecting a sour gas at a collection location, which has an associated sweetening device, and delivering a solvent to the sweetening device from a regeneration device remote therefrom. The sour gas is treated at the collection location with the solvent in the associated sweetening device to form a sweetened gas and a sour gas-rich solvent. The sweetened gas is transported from the sweetening device to a gas processing plant remote therefrom, and the sour gas-rich solvent from the sweetening device is delivered to the regeneration device for regeneration therein.
