  • Patent number: 11156056
    Abstract: In some embodiments, a method for executing an emergency disconnect sequence in shallow water depth includes unlatching a lower marine riser package (LMRP) of a blowout preventer (BOP) from a lower stack of the BOP. The BOP defines a wellbore fluidically coupled to the subsea wellhead. A tubular is disposed within the wellbore. The method further includes shearing the tubular and sealing the wellbore. In response to an indication that a vessel operably coupled to the BOP has failed to keep station, an unlatch sequence and a shear and seal sequence are initiated, such that each sequence occurs at least partially simultaneously. The unlatch sequence includes disconnecting the LMRP from the lower stack, and the shear and seal sequence includes activating the lower stack to shear the tubular in less than about one second and seal the wellbore.

  • Patent number: 11002077
    Abstract: A drill bit forming a borehole in the earth may be urged sideways, creating a curve in the borehole, by a cross-sectional shape of the borehole. For example, a borehole with a cross-sectional shape comprising two circular arcs of distinct radii, one larger and one smaller than a gauge of the drill bit, may push the drill bit away from the smaller circular arc and into the larger circular arc. Forming a borehole with such circular arcs may be accomplished by extending a cutting element from a side of the drill bit for only a portion of a full rotation of the drill bit. The relative radii and angular ranges occupied by the circular arcs may affect a radius of curvature formed in the borehole. The radii and angular ranges occupied by these circular arcs may be adjusted by altering the timing of extension and retraction of the extendable cutting element.

  • Patent number: 10180043
    Abstract: A method is for establishment of a new well path from a well. The method comprises disposing and anchoring a plug base in a casing in the well; lowering a perforation tool into the casing; forming holes in the casing along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool and into the casing and further out into an annulus; pumping a fluidized plugging material out through the flushing tool and into the casing and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across a cross section of the well; wherein the outlets in the flushing tool are angled non-perpendicularly relative to a longitudinal axis of the flushing tool.

  • Patent number: 10041322
    Abstract: A gripping tool having a mandrel reciprocatable within a slide member, the mandrel having a top connector for connecting to a tubular string and a bottom connector for connecting to a cutting tool, the slide member having at least one radially outwardly biased friction member and a slip cage with at least one window through which a slip is deployable, by movement of the mandrel within the slide member, to engage and grip a section of casing to be removed from a well, the mandrel being rotatable by rotation of the tubular string to operate the cutting tool with the gripping tool in the gripping mode. After detachment of the section of casing by the cutting tool, the gripping tool and the gripped section of casing are pulled from the well. The gripping mode is restorable to a running position to reset the tool in the casing.

  • Patent number: 9945197
    Abstract: A system and method for positioning a tool within a tubular segment or a tubular tool, wherein the interior surface of the tubular segment or tubular tool is provided with one or more pluralities of grooves, each defining a selected profile. A downhole tool is lowered into the tubular segment or tubular tool, having a blade in communication therewith. The blade includes a plurality of protruding members thereon, which define a profile complementary to one of the selected profiles formed by one of the pluralities of grooves. A biasing member biases the blade toward the interior surface of the tubular segment or tubular tool to engage the protruding members of the blade within the complementary profile of the tubular segment or the tubular tool. The system and method further include a slip and wedge assembly usable to position a tubular segment or tubular tool within a tubular member or wellbore.

  • Patent number: 9926758
    Abstract: Disclosed are systems and methods for removing components of a subsea well having a wellhead located on a seabed and multiple well casings connected to the wellhead and penetrating the seabed. A cutting tool is lowered from a floating vessel to a predetermined cut location in the subsea well. The cutting tool is at the end of a utility line connected to an actuator located on the floating vessel. The cutting tool is used to sever the multiple well casings at the predetermined cut location such that the multiple well casings are completely severed concurrently. The wellhead and the severed multiple well casings are raised together from the seabed to the floating vessel as a single assembly. Various forms of the cutting tool are disclosed. The methods disclosed can include an integrated procedure for dispensing cement to plug the well at the seabed as the well components are being removed.

  • Patent number: 9909378
    Abstract: A method is for cutting of at least one line disposed along a pipe string in a well. The method includes (A), using a cutting tool for selective cutting activation and provided with at least one cut-forming means for cutting in a radial direction outward from the cutting tool; and (B) lowering the cutting tool to a longitudinal section where the cutting is to be carried out. In (A), a cutting tool is used for controlled cutting in a peripheral direction and distributed in an axial direction relative to the cutting tool. The method further includes (C), activating the cutting tool and cutting, in the radial direction through and past the wall of the pipe string, at least one peripherally extending hole collectively covering the entire circumference of the pipe string, and also distributing the hole in the axial direction.

  • Patent number: 9850736
    Abstract: A settable down hole tool is of increased drillability and/or of increased expansibility. The improvement in drillability can be caused by fracturing cast iron slips into a large number of small pieces that can be circulated out of a well without further reduction in size. The improvement in expansibility can be partially caused by providing an expander cone of increased hardness thereby allowing an increased angle on the expander cone and slips. The improvement in expansibility can be partially caused by increasing the thickness of the slips.

  • Patent number: 9822629
    Abstract: Casing removal operations may utilize an analytical model to the estimate the total force to (1) break bonding between a cut casing and the annular materials contained between the cut casing and the surrounding borehole and (2) pull the cut casing upward through the borehole while taking into account frictional forces inside and outside the cut casing, shear forces, and the like. Such models may further predict the casing overpull and total tension needed to extract the cut casing from the borehole. Using these models in conjunction with the specifications of the casing retrieval equipment may allow for determining the cutting depth for producing the cut casing with higher accuracy than previously available.
