  • Patent number: 11319778
    Abstract: An apparatus, system, and method according to which debris is cleaned from a casing that extends within a wellbore. The method generally includes running a downhole tool into the casing, the downhole tool comprising an isolation tool, a setting tool, and a casing scraper. Debris is then cleaned from an inner surface of the casing at a depth interval using the casing scraper. After cleaning the debris from the inner surface of the casing, the isolation tool is set against the inner surface of the casing at the depth interval using the setting tool to isolate a zone of the wellbore. After setting the isolation tool against the inner surface of the casing, a wellbore operation is performed in which isolation of the zone of the wellbore is required. The downhole tool is then drilled out of the casing using a drill bit.

  • Patent number: 11268365
    Abstract: The disclosure is directed to a method and system that estimates the number of active fractures for a given hydraulic fracturing fluid pressure. The hydraulic fracturing pressure can be correlated to a corresponding hydraulic fracturing fluid absorption rate of downhole fractures. Using the pressure and rate correlation, an active fracture ratio can be determined and then utilized to estimate the number of active fractures at a given hydraulic fracturing fluid pressure. In other aspects, a target fluid pressure is represented by a curve or other shape corresponding to a fluid friction model so that the fluid pressure correlation to the fluid absorption rate can be utilized to compute the active fracture ratio. The disclosed system is operable to control a well site pump system to adjust the fluid pressure and fluid composition, to monitor the downhole fluid, to collect the fluid values, and to compute an estimated active fracture ratio.

  • Patent number: 11255159
    Abstract: Cleanout tools and related methods of operation. At least some of the example embodiments are cleanout tools including a tool body that defines an internal annular channel, a joiner coupled to the tool body, a sleeve telescoped within the joiner and tool body, and a ball disposed within the annular channel. The ball held within the annular channel by the sleeve, and the ball configured to move along the annular channel under force of fluid pumped into the cleanout tool. The ball creates a pulsing of fluid streams exiting the tool body. Moreover, in some example systems the fluid streams created by the tool body intersect the inside diameter of a casing at non-perpendicular angles.

  • Patent number: 11248430
    Abstract: A multi-string section milling tool has a longitudinally extending tubular body with mill carriers carrying hardened cutters that pivotally extend from a mill window in the tubular body by upward movement of a drive plunger. A downwardly biased piston mounted to the upper end of a flow tube is slidably inserted through a stationary thimble below the piston. The lower end of the flow tube is attached to a drive plunger which is pivotally attached to drive yoke links pivotally attached the mill carriers. The piston and thimble creates a pressure chamber in the milling tool. Fluid pressure in the pressure chamber moves the piston, flow tube and drive plunger upward to pivotally extend the drive yoke links and mill carriers radially outward through the mill window. Cessation of fluid pressure in the pressure chamber retracts the mill carriers.

  • Patent number: 11236562
    Abstract: A safety drilling system for preventing collapse of water-sensitive formation in the upper part of a high-pressure saltwater layer, which includes a wellhead equipment, a downhole drilling tool, a first injection pipeline, a second injection pipeline, a first return pipeline and a second return pipeline. Upon encountering a high-pressure saltwater layer while drilling, the system injects heavy mud into the annulus of a wellhead through the first injection pipeline to form a heavy mud cap, such that a fluid column pressure in the annulus balances the pressure of the high-pressure saltwater layer. In this case, a fluid column pressure in a drill string is lower than the pressure of the high-pressure saltwater layer.

  • Patent number: 11230916
    Abstract: A technique facilitates use of tools downhole during well operations. According to an embodiment, the technique employs a frac stack which may be coupled to a wellhead. The frac stack may include a flow control device which opens and closes a bore extending through the wellhead. A lubricator may be coupled to the frac stack. The lubricator includes a tool trap which opens and closes to facilitate controlled movement of a tool along the bore. A tool position detection system is used to detect a position of the tool in the tool trap to ensure, for example, removal of the tool from the frac stack before closure of the flow control device.
