  • Patent number: 10273769
    Abstract: A coiled adaptive seat is held to a smaller diameter for delivery with a tool that can feature a locating lug for desired alignment of the seat with an intended groove in the inner wall of a tubular. The release tool retracts a cover from the seat allowing its diameter to increase as it enters a groove. Alternatively the adaptive seat is released near the groove and pushed axially in the string to the groove for fixation. Once in the groove the inside diameter of the string is a support for a blocking object so that sequential treatment of parts of a zone can be accomplished. The blocking object is removed with pressure, dissolving, milling or disintegration leaving a narrow ledge in the tubular bore from the seat that can simply be left in place or milled as well. An E4#10 from Baker Hughes is modified for adaptive seat delivery.

  • Patent number: 10273791
    Abstract: A control system for a CO2 fracking system includes a phase detector, a control valve, and a controller. The phase detector is disposed proximate to at least one of an inlet conduit and an outlet conduit of a fracking component. The control valve is fluidly coupled to the inlet conduit. The controller is communicatively coupled to the phase detector, the control valve, and the fracking component. The phase detector is configured to determine CO2 phase in at least one of a CO2 stream incoming into the fracking component and CO2 phase discharged from the fracking component, and to generate an input signal based on the phase. The controller is configured to control one or both of a flow of the incoming CO2 stream into the fracking component via the control valve and an operation condition of the fracking component, based on the input signal received from the phase detector.

  • Patent number: 10240449
    Abstract: Compositions and methods are provided for treatment of a wellbore in a subterranean formation. Exemplary compositions comprise a mixture of particles, some of the particles being degradable and other particles being elongated, having good compressive strength, and not being readily degradable at the conditions of the formation. The mixture of particles can temporarily bridge or plug fractures within the formation, and thus acts as a temporary diversion agent. After the degradable particles dissolve, the particles which are not readily degradable can remain in the fracture, helping to keep the fracture open and acting as a proppant.

  • Patent number: 10161236
    Abstract: Methods of fracturing a subterranean formation are described wherein sintered ceramic proppants are used in at least two different stages. Each stage can utilize the same or a different type of proppant relative to one or more of the other stages, and the same or a different type of fracturing fluid relative to one or more of the other stages. At least one of the stages uses a proppant having a monodispersity of 3-sigma distribution or lower. A first stage can be used that exhibits at least one proppant performance property having a first value. A second stage can be used that exhibits the same proppant performance property as the first stage but at a value that differs from the first value by at least 10%.

  • Patent number: 10132147
    Abstract: Systems and methods for analyzing and designing a customized pulse fracturing operation for fracturing a wellbore in a reservoir formation are disclosed. Pulsed fracturing can create multiple fractures that radiate away from the wellbore while minimizing near wellbore damage. This network can further be extended into the reservoir by utilizing an optimized pumping rate over a predetermined amount of time. The optimized pulse rate and duration can be determined by using a geomechanical and a reservoir simulator which can help in quantifying the production efficiency of the induced fracture network.
