Abstract
A method and system of forming a lateral wellbore in a time and trip saving manner using a mill/drill to locate and place a casing window. In one aspect of the invention, a lateral wellbore is drilled with liner which is subsequently left in the lateral wellbore to line the sides thereof. In another aspect, the mill/drill is rotated with a rotary steerable system and in another aspect, the mill/drill is rotated with a downhole motor or a drill stem.
Claims (28)
1. A method of expanding a liner extending into a lateral wellbore through a window in casing disposed in a wellbore, comprising:
providing an expander having at least one radially extendable expander member disposed about a body, each expander member having a retracted and an extended position and each member having a piston surface for moving the member to the extended position with a pressurized fluid, wherein, in the extended position, the expander members are biased to permit radially inward movement due to inwardly directed forces from surfaces surrounding the liner; and expanding the liner at least across a portion of the liner proximate the window with the expander.
providing an expander having at least one radially extendable expander member disposed about a body, each expander member having a retracted and an extended position and each member having a piston surface for moving the member to the extended position with a pressurized fluid, wherein, in the extended position, the expander members are biased to permit radially inward movement due to inwardly directed forces from surfaces surrounding the liner; and expanding the liner at least across a portion of the liner proximate the window with the expander.
2. A method of expanding a liner extending into a lateral wellbore through a window in casing disposed in a wellbore, comprising:
locating an expander inside the liner, the expander having at least one radially extendable member movable between a first extended position and a second lesser extended position, wherein a biasing mechanism biases the at least one radially extendable member toward the first extended position;
operating the expander to the first extended position; and moving the expander axially within the liner to expand a length of the liner across the window.
locating an expander inside the liner, the expander having at least one radially extendable member movable between a first extended position and a second lesser extended position, wherein a biasing mechanism biases the at least one radially extendable member toward the first extended position;
operating the expander to the first extended position; and moving the expander axially within the liner to expand a length of the liner across the window.
3. A method of forming a lateral wellbore, comprising:
inserting a liner having a mill/drill disposed at one end into a cased wellbore having a casing therein;
cutting a window in a wall of the casing with the mill/drill;
drilling into a formation proximate the window with the mill/drill while advancing the liner to form the lateral wellbore; and expanding the liner through the window.
inserting a liner having a mill/drill disposed at one end into a cased wellbore having a casing therein;
cutting a window in a wall of the casing with the mill/drill;
drilling into a formation proximate the window with the mill/drill while advancing the liner to form the lateral wellbore; and expanding the liner through the window.
4. A method as claimed in claim 3, wherein the liner and mill/drill are rotationally coupled.
5. A method as claimed in claim 3 or 4, wherein the cutting and the drilling include rotating the mill/drill with a rotational force provided at a surface of the well.
6. A method as claimed in claim 3, wherein the liner and mill/drill are rotationally independent and rotation of the mill/drill for the cutting and the drilling is provided by a downhole motor disposed thereabove.
7. A method as claimed in any one of claims 3 to 6, wherein the mill/drill comprises an inner portion and an outer portion, the inner portion being selectively removable from the outer portion of the mill/drill.
8. A method as claimed in any one of claims 3 to 7, further comprising directing the mill/drill towards the wall with a diverter fixed in the cased wellbore therebelow.
9. A method as claimed in any one of claims 3 to 7, further comprising directing the mill/drill using a bent liner.
10. A method as claimed in any one of claims 1 to 9, further comprising expanding a portion of the liner disposed in the wellbore.
11. A method as claimed in any one of claims 1 to 10, further comprising expanding a portion of the liner disposed in the lateral wellbore.
12. A method of expanding a liner extending into a lateral wellbore through a window in casing disposed in a wellbore, comprising:
providing an expander having at least one radially extendable member, the radially extendable member having a first unextended position, a second fully extended position and a range of positions between the first and second positions wherein the radially extendable member moves from the first position upon application of a force to the radially extendable member;
locating the expander inside the liner;
applying the force to the radially extendable member;
engaging the radially extendable member with an inner diameter of the liner;
and expanding the liner across the window, wherein the radially extendable member is positioned within the range for at least a portion of the expansion.
providing an expander having at least one radially extendable member, the radially extendable member having a first unextended position, a second fully extended position and a range of positions between the first and second positions wherein the radially extendable member moves from the first position upon application of a force to the radially extendable member;
locating the expander inside the liner;
applying the force to the radially extendable member;
engaging the radially extendable member with an inner diameter of the liner;
and expanding the liner across the window, wherein the radially extendable member is positioned within the range for at least a portion of the expansion.
13. A method as claimed in claim 12, wherein expanding the liner across the window includes:
expanding a first portion of the liner disposed in the wellbore having a first set of characteristics to a first diameter and shape;
expanding a second portion of the tubular disposed in the window having a second set of characteristics to a second diameter and shape.
expanding a first portion of the liner disposed in the wellbore having a first set of characteristics to a first diameter and shape;
expanding a second portion of the tubular disposed in the window having a second set of characteristics to a second diameter and shape.
14. A method as claimed in claim 12, wherein expanding the liner across the window includes:
expanding a first portion of the liner disposed in the lateral wellbore having a first set of characteristics to a first diameter and shape;
expanding a second portion of the tubular disposed in the window having a second set of characteristics to a second diameter and shape.
expanding a first portion of the liner disposed in the lateral wellbore having a first set of characteristics to a first diameter and shape;
expanding a second portion of the tubular disposed in the window having a second set of characteristics to a second diameter and shape.
15 15. A method as claimed in any one of claims 1 to 14, further comprising removing at least a portion of the liner extending into the wellbore from the window.
