  • Publication number: 20230166305
    Abstract: A method for removing fouling from a pipeline includes determining the location of fouling in the pipeline. Once determined, the method further includes installing a hot tap in the pipeline. A flex conduit is inserted into the pipeline through the hot tap and a treatment fluid is flowed into the pipeline through the conduit. The treatment fluid is used to remove the fouling from the pipeline. Once the fouling is sufficiently removed, the flexible conduit is removed from the pipeline.

  • Patent number: 10738913
    Abstract: A subsea pump and power system having a base unit positioned on the seabed to which is detachably mounted a power module tethered to a surface power source via a power umbilical. The base unit includes process pumps for carrying out subsea pumping operations and is lowered by a heavy lift cable into position on the seabed adjacent a hydrocarbon production facility prior to lowering of the power module on a tether. The power module includes a power unit which may include an electrical motor, or a hydraulic pump or both, one or more of which are driven by the umbilical extending from the surface. The tether supports the weight of the power module as it is lowered to the base unit and includes an electrical umbilical, a hydraulic umbilical or both.

  • Patent number: 10711536
    Abstract: A selective stimulation system includes coiled tubing in which a distributed sensor array is disposed. The distributed sensor array is to measure hydrocarbon production parameters along the distributed sensor array in a wellbore of a formation. A selective fracturing apparatus is coupled to the coiled tubing. The selective fracturing apparatus is to fracture selected areas of the wellbore. A controller is coupled to the distributed sensor array and controls operation of the selective fracturing apparatus based on the measured hydrocarbon production parameters.

  • Publication number: 20200102813
    Abstract: A rapid deployment, subsea chemical injection skid assembly includes a non-buoyant skid lowered on a weight bearing line from a surface vessel. The skid carries a chemical injection pump, as well as at least one chemical tank in fluid communication with the chemical injection pump. The skid assembly may include a recirculation/mixing system to limit separation or solids drop out of chemicals arising from medium or long-term storage of chemicals in the chemical tank. The skid assembly may include a seawater filtration system to supply seawater for mixing with chemicals prior to injection. The skid assembly is operable by a separately tethered remotely operated vehicle.
