  • 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: 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: 10053969
    Abstract: A one trip system for perforating and fracking multiple intervals uses a releasable barrier. The barrier can be an inflatable. A pressure booster system is associated with the BHA so that the existing hydrostatic pressure is boosted when the gun or portions thereof are fired. After firing in one interval, the BHA is raised and the barrier is redeployed and the pattern repeats. Instruments allow sensing the conditions in the interval for optimal placement of the gun therein and for monitoring flow, pressure and formation conditions during the fracturing. Circulation between gun firings cleans up the hole. If run in on wireline a water saving tool can be associated with the BHA to rapidly position it where desired. A multitude of perforation charges mounted in the BHA can be selectively fired by selected corresponding detonator based on a predetermined sequence or surface telemetry command.

  • Patent number: 9529104
    Abstract: In some aspects, a closed boundary is computed based on locations of microseismic events associated with a stimulation treatment of a subterranean region. Based on the boundary, a stimulated reservoir volume (SRV) for the stimulation treatment is identified. The boundary encloses a first subset of the locations and a second, different subset of the locations reside outside the boundary.

  • Patent number: 9458685
    Abstract: A method, computer-readable medium and apparatus for delivering a material to a downhole location in a formation is disclosed. A device is operated at a surface location to produce an action at the downhole location related to delivery of the material to the formation. A downhole parameter is measured at the downhole location, wherein the downhole parameter is affected by the operation of the device at the surface location. The downhole parameter is measured using a sensor proximate the downhole location. The measured downhole parameter is used to alter operation of the device at the surface location to deliver the material to the formation at the downhole location.

  • Patent number: 9453399
    Abstract: A method and apparatus for sequestering carbon dioxide (CO2) gas and releasing natural gas from underground coal and/or gas shale formations using CO2 gas captured from the flue gas of a coal burning power plant, and processing it to produce cold liquid pressurized CO2, and injecting the cold liquid CO2 under pressure to create fractures within the formation and causing the CO2 to be adsorbed into the coal or gas shale and natural gas (CH4) to be desorbed, released and recovered. A special pressure cycling process is used to enable the pressure within the formation to be increased and decreased, including allowing the liquid CO2 to change phase to a gaseous CO2, and injecting the liquid CO2 under pressure repeatedly, which causes greater expansion of the proliferation zone within the formation, and more efficiently releases CH4.

  • Patent number: 9267368
    Abstract: One or more inflatables are used to initiate fractures in a formation. The onset of fractures after inflation to a predetermined pressure also results in damage to the inflatable and the ability to follow up the stress that initiated the fracture with high flow at high pressure to further propagate the initiated fractures at a location close to their origin. In another variation the inflatable can have openings that are small enough to allow inflation to initiate the fractures and yet continue to allow fluid flow through the openings to propagate the fractures. In yet another variation sliding sleeves with ball seats can be sequentially operated to inflate to fracture followed by opening an adjacent port to propagate.

    Abstract: A well system can include an accumulator in communication with a wellbore, whereby the accumulator applies pressure to the wellbore. A method of maintaining a desired pressure in a wellbore can include applying pressure to the wellbore from an accumulator in response to pressure in the wellbore being less than the desired pressure. Another well system can include a dampener in communication with a wellbore isolated from atmosphere, whereby the dampener mitigates pressure spikes in the wellbore.

  • Patent number: 9243485
    Abstract: A shockwave generator pre-treats one or more production zones within a well to facilitate recovery of liquid and gaseous hydrocarbons from the well. The well may be heated to a particular temperature, where after a cooling agent is introduced through the shockwave generator which effects a cooling action in the walls of the well and induces cracking which is propagated by the tremors or shocks of the cooling agent as it exits the generator. The initiated cracks may be further propagated using one or more additional stimulation methods, including a freeze-thaw method which is implemented through a subsystem having overlapping components with the shockwave generator subsystem.
