Abstract
A method of treating and completing a well includes positioning a downhole tool within a well. The downhole tool includes an elongated body defining a central passageway and including a plurality of production openings and at least one frac opening, a frac mandrel disposed within the central passageway, and a packer disposed about the elongated body. The method further includes securing the downhole tool in the well by the packer, fracing a formation through the frac opening, and producing a fluid from the formation through the production openings.
Claims33
A downhole tool comprising:
- a body defining a passageway and including a plurality of production openings and at least one frac opening;
- a packer disposed about the body and operable to secure the downhole tool in a well;
- and
- a frac mandrel operable within the passageway, wherein the frac mandrel is operable to facilitate a production enhancement operation through the body and further operable to set the packer.
A method of treating a well, comprising the steps of:
- positioning a downhole tool within a well, the downhole tool comprising:
- a body defining a passageway and including a plurality of production openings and at least one frac opening;
- a frac mandrel disposed within the passageway;
- and
- a packer disposed about the body;
- securing the downhole tool in the well by setting the packer with the frac mandrel;
- and
- performing a production enhancement operation through the body.
A method of treating and completing a well, comprising the steps of:
- positioning a downhole tool within a well, the downhole tool comprising:
- a body defining a passageway and including a plurality of production openings and a plurality of frac openings;
- a frac mandrel disposed within the passageway;
- a setting tool coupled to an end of the frac mandrel;
- and
- a plurality of packers disposed about the body;
- setting a liner hanger with the setting tool;
- securing the downhole tool in the well by setting the packers with the frac mandrel;
- successively fracing a formation through respective ones of the frac openings to create a plurality of fractures in the formation at different locations within the well, wherein after each fracing step the method comprises the steps of:
- packing the fracture by reducing a flow of process fluid through an annulus between the body and the well;
- and
- reversing the circulation of process fluid through the downhole tool;
- removing the frac mandrel from the well when finished with the last fracing step;
- and
- producing a fluid from the formation through the production openings.
A method of treating and completing a well formed in a subterranean formation having one or more production zones, comprising the steps of:
- positioning a downhole tool within the well, the downhole tool having a body formed with a plurality of frac openings disposed along its length and a plurality of production openings disposed along its length;
- securing the downhole tool in the well by one or more packers;
- performing a production enhancement operation through the body of the downhole tool, wherein the production enhancement operation includes the step of pumping a fracturing fluid through the body of the downhole tool and out the plurality of frac openings at a sufficient pressure to fracture one or more of the production zones;
- and
- producing a fluid from the one or more production zones through the plurality of production openings formed in the body;
- wherein at least two of the above steps are performed in one trip into the well.
