Abstract
In one instance, a method of completing a well includes providing a drilling-uncompleted adapter having a first side on an upper portion and a second side on a lower portion and attaching the second side of the drilling-uncompleted adapter onto a casing head of a well. The method further includes attaching at least one fracturing valve to the first side of the drilling-uncompleted adapter and fracturing the well. The method also includes removing the drilling-uncompleted adapter after fracturing and attaching tubing head to the casing head for production. The tubing head does not endure the fracturing.
Claims21
A method of completing a well comprises:
- providing a drilling-uncompleted adapter having a first side on an upper portion and a second side on a lower portion;
- attaching the second side of the drilling-uncompleted adapter onto a casing head of a well;
- attaching at least one fracturing valve to the first side of the drilling-uncompleted adapter;
- fracturing the well;
- removing the drilling-uncompleted adapter;
- and
- attaching tubing head to the casing head for production.
A fracturing assembly for use on an oil well comprising:
- a casing head having a first flange on an upper side;
- a drilling-uncompleted adapter having a first side on an upper side and a second side on a lower side, the drilling-uncompleted adapter having an inner annulus having an upper portion and a lower portion;
- a casing hanger or a portion of casing disposed at least partially in the inner annulus of the drilling-uncompleted adapter forming a sealing chamber;
- an energizeable seal disposed within the sealing chamber;
- and
- the drilling-uncompleted adapter having an injection port with a conduit from the injection port to the inner annulus proximate the sealing chamber to provide an energizing, pressurized fluid during fracturing operations.
A method of preparing a well for production comprises:
- providing a drilling-uncompleted adapter having a first side on an upper portion and a second side on a lower portion, the drilling-uncompleted adapter comprising:
- a body having an inner annulus and having at least one injection port, which has a conduit from the injection port to a sealing chamber formed on a portion of the inner annulus, whereby a seal may be energized during fracturing, and
- wherein the drilling-uncompleted adapter is valve free;
- attaching the second side of the drilling-uncompleted adapter onto a casing head of the well;
- attaching at least one fracturing valve to the first side of the drilling-uncompleted adapter;
- fracturing the well;
- removing the drilling-uncompleted adapter;
- and
- attaching a tubing head to the casing head for production.
