Abstract: An apparatus and method for connecting a lateral well bore to a vertical well bore using a tieback liner while providing full bore access in the vertical well bore casing. The tieback liner is rotationally aligned with respect to a window of the casing by locating a key slot formed above the window and longitudinally aligned by using a no-go device to locate the bottom edge of the window. The tieback liner includes a snap sleeve that extends into a window of the main well bore casing and connects the tieback liner to the casing. The section of the casing receiving the snap sleeve is of a larger inner diameter than the other sections of casing. The connection between the tieback liner and casing prevents the tieback liner from rotating, tilting, or moving laterally with respect to the casing. The connection imparts significant resistance to formation loading applied at the junction.

Abstract: A method of anchoring a whipstock on the mill or drill body using an anchor extendible to engage an eyelet formed or provided on the whipstock to run in a mill and whipstock in one trip. The anchor is retractable into the body of the drill so that the drill can pass by the whipstock during lateral drilling and out the casing wall without interference. The anchor preferably is extended and retracted by hydraulic force controlled remotely by the operator. The anchor is preferably shaped to match and conform to the outer wall of the drill so that in the closed position, the anchor is contiguous with and does not extend beyond the outer diameter of the drill body. Part of the drill body is preferably removed to allow the anchor to nest within the space provided by the removal of the drill body.

Abstract: The side tracking system includes a window mill having a full diameter cutting surface and a reduced diameter tapered cutting surface and a whipstock having a ramp engaging the reduced diameter cutting surface. The materials of the whipstock have a first cutablity and the materials of the casing have a second cutability. The reduced diameter cutting surface contacts the whipstock ramp at a first contact area and the full diameter cutting surface contacts the wall of the casing at a second contact area. As weight is applied to the mill, there is a first contact stress at the first contact area and a second contact stress at the second contact area. A cutability ratio is the first cutability divided by the second cutability and a contact stress ratio is the first contact stress divided by the second contact stress. The mill cuts the casing rather than the whipstock by maintaining the product of the cutability ratio and the contact stress ratio less than one.

Abstract: Enhanced horizontal drilling systems and methods encompass the production of crude oil from wells drilled from a subterranean production facility. This approach has the location of the well head below the oil reservoir to improve flow rate and recovery due to the consistent voiding of fluids by gravity flow within the well bore to the well head allowing well bore production pressure to achieve extremely low fluid pressure or even a vacuum of up to 15 PSI. This method increases oil recovery rate and factor, and lowers production costs. The present method is production of shallow crude oil by way of long horizontal or near horizontal boreholes drilled and serviced from a subsurface workroom. The subsurface workroom serves as both the drilling platform and the place to which production is centrally accumulated from the wells. Oil is collected in a central facility and is then lifted to the surface utilizing pumps.

Abstract: A system and method are disclosed for forming and reentering multiple lateral wells through a wall of a common well bore. The system includes an anchor, an orienting member, an extension member, a diverter and a probe releasably connected by one or more unilateral connections and a multilateral connection. The unilateral connection restricts rotational and translational movement of the system upon makeup, and maintains alignment between components thus joined in a single direction. The multilateral connection also restricts rotational and translational movement of the system upon makeup, however, enables alignment between components thus joined in multiple directions. Thus, use of the system enables lateral orientation of the diverter at multiple positions, positioning the diverter at multiple longitudinal positions and selective reentry of each lateral well formed.

Abstract: A well has a vertical casing with a window, and a lateral wellbore which communicates with the window, and which may have a casing or liner. A window assembly aligned with the window has respective passageways for first and second tubing strings, and has a concave surface for deflecting the first tubing string out into the lateral wellbore. The passageway for the second tubing string has a portion which is inclined at a very small angle with respect to a vertical centerline of the vertical casing.

After the locator effects rotational orientation, the coupling mechanism is released and then permits the first tubing string to move therepast without damage. A seal assembly on the first tubing string is covered by a protective sleeve as it is inserted into the well, and exits the protective sleeve after entering the lateral wellbore.
