Abstract

A wellbore tool system for use within a wellbore includes a stage packer shoe, having a lower body extending from a first end to a second end; an upper body attached to the lower body at the second end; and circulation ports extending through a thickness of the upper body; a metal cup having a predetermined diameter as determined by a diameter of the wellbore; the metal cup secured around a periphery of the lower body of the stage packer shoe such that the metal cup extends away from the periphery; the metal cup is to engage with the wellbore enough to have differential pressure holding capability between the stage packer shoe and the wellbore; and the differential pressure of the metal cup is dependent on a strength of the cup and the wellbore with which the metal cup is engaged.

Claims (31)

1. A wellbore tool system for use within a wellbore, comprising:

a stage packer shoe, having:

a lower body extending from a first end to a second end;

an upper body attached to the lower body at the second end, the upper body forming an inner area; and

a plurality of circulation ports extending through a thickness of the upper body, the plurality of circulation ports are in fluid communication with the inner area;

a metal cup having a predetermined diameter as determined by a diameter of the wellbore;

the metal cup is secured around a periphery of the lower body of the stage packer shoe such that the metal cup extends away from the periphery;

a plug seat extending from an inner surface of the inner area, the plug seat forming an opening between the lower body and the upper body;

a first plug configured to engage with the plug seat and configured to close the opening, the first plug is configured to force all fluid through the plurality of circulation pores; and

a second plug configured to engage with the upper body, the second plug is configured to cover the plurality of circulation ports;

wherein the metal cup is configured to engage with the wellbore enough to have differential pressure holding capability between the stage packer shoe and the wellbore; and

wherein the differential pressure of the metal cup is dependent on a strength of the cup and the wellbore with which the metal cup is engaged.

2. The system of claim 1 , wherein the metal cup is integrally secured to the periphery of the lower body.

3. The system of claim 1 , wherein the metal cup is secured to the periphery of the lower body via a stop collar.

4. The system of claim 1 , further comprising:

a guide nose attached to the lower body at the first end.

5. A method of wellbore operations, the method comprising:

providing the system of claim 1 ;

drilling the wellbore to a desired depth until the wellbore penetrates the cap rock located above the producing formation; and

running the stage packer shoe tool into the wellbore until the metal cup is located at a depth within the wellbore above the producing formation;

wherein the metal cup creates an annular seal within the producing formation.

6. The method of claim 5 , further comprising:

dropping a freefall plug from a ground surface into the stage packer shoe tool; wherein the freefall plug engages with a freefall plug landing seat positioned within lower body; and

wherein the freefall plug forces fluid through a plurality of circulation ports extending through a thickness of the upper body.

7. The method of claim 6 , further comprising:

performing one or more pumping operations through a wellbore casing.

8. The method of claim 7 , further comprising:

inserting the second plug into the wellbore casing to engage with a closing seat of the stage packer shoe tool;

wherein engagement of the second plug with the closing seat closes a sleeve of the stage packer shoe tool.

9. The method of claim 8 , further comprising:

releasing surface pressure from the wellbore and performing drill out operations.
