  • Patent number: 11268362
    Abstract: The invention relates to the completion of hydrocarbon wells using acid. It is known to create cavities in the formation using acid, which then collapse to leave a highly permeable region for production of hydrocarbons. An issue with this technique can be that the wellbore/tubing adjacent the cavity is damaged. The invention involves passing thin conduits through the formation transversely of the main wellbore, through which conduits acid is delivered to create unstable cavities at a distance from the main wellbore thereby stimulating production without risking instability of the main wellbore.

  • Patent number: 11156071
    Abstract: A system and method of wellbore operations that forms notches into a subterranean formation that circumscribes a wellbore prior to fracturing the formation. The notches extend past the hoop stress regime that surrounds the wellbore so that fractures formed by fracturing are oriented in a designated plane. In one example, a fluid jet is used to form the notches, and which is discharged from a nozzle that rotates about a downhole tool. The nozzle is set in a sleeve that is rotatable about the downhole tool, and pressurized fluid is delivered to a plenum disposed on an inner surface of the sleeve. The nozzle is oriented oblique to a radius of the sleeve, so that the fluid being discharged from the nozzle generates a force that rotates the sleeve.

    Abstract: A delivery tool creates relative axial movement to retract a retaining sleeve from an adaptive seat so that the adaptive seat can release from the delivery tool and find support in a tubular string. The relative movement is created directly with a power charge acting on a piston attached to the retaining sleeve. Movement of the retaining sleeve releases support dogs that position the delivery tool when releasing the adaptive seat. The adaptive seat is protected for running in with a collapsible ring structure that passes through the adaptive seat opening when the delivery tool is pulled out of the hole. The retaining sleeve is replaced and the power charge is renewed to allow the delivery tool to be used more than once.

  • Patent number: 10895152
    Abstract: Breaking rock and concrete, based upon a Controlled-Foam Injection or PCF (Penetrating Cone Fracture) uses a high-pressure fluid to pressurize a pre-drilled hole. A high pressure seal is formed between the injection barrel and walls of the pre-drilled hole in the material to be broken. A leak-free poppet valve holds a fluid in a pressure vessel before rapid discharge. Variable charges of foam/water are generated and delivered to the breaker. The injection barrel is prefilled with a low viscosity fluid. An annular reverse acting poppet valve allows concurrent injection of chemical additives and/or micro particles to modify foam viscosity during its high pressure release into the material to be broken. A high pressure foam generator is compact and reliable. Removal and wash-out of the seal frees the injection barrel.

  • Patent number: 10815050
    Abstract: The present invention is a modular system for delivering material directly to a blender hopper. The system includes primary base and optional secondary base modules supporting surge hoppers which receive material from material containers. The surge hopper may then dispense the material directly and rapidly to the blender hopper by gravity feed. During continuous operation, exhausted material containers may be removed from the surge hoppers and replaced with full material containers as material empties from the surge hoppers. This allows steady, high-volume flow of material to the blender hopper.

  • Patent number: 10738569
    Abstract: An oil and gas configuration is disclosed that creates and uses a single straight-line fluid path between a zipper module and a fracturing (or Christmas) tree. The single straight-line fluid path is created through connecting a series of valves (e.g., manual or automatic gate or plug valves) that coaxially share inner fluid passageways for transporting hydraulic fracturing fluid between the zipper module and the fracturing tree. The hydraulic fracturing fluid flows along the single straight-line fluid path upon from the zipper module to the fracturing tree. The fracturing tree is equipped with a multi-way block that directs—through one or more internal angled walls—the hydraulic fracturing fluid downward and toward a wellhead.

  • Patent number: 10711585
    Abstract: Techniques in horizontal well completions that facilitate multistage fracturing may be performed in shale gas reservoirs. The techniques may involve the creation of large scale fracture networks, connecting the reservoir and the wellbore, facilitated by activating pre-existing natural fractures (NFs). In addition, geo-mechanical characteristics facilitate the optimization of maximum stimulated reservoir volumes (SRVs). In particular, completion optimization patterns are provided for horizontal wellbores, designated herein as altered alternate fracturing (AAF) completions. Completion optimization patterns may involve a multi-step combination of simultaneous and alternate fracturing patterns. Additionally, the dynamic evolution and progression of NF growth are modeled using a variety of alternative criteria. Further, specific analyses are provided of how the well completion pattern influences the fracture network.
