Methods and systems for creating an interventionless conduit to formation in wells with cased hole

1. A tool comprising:

an upper body;

a lower body configured to be temporarily coupled to the upper body at a first location in a first position; and the lower body being configured to be disengaged from the upper body at the first location in a second position, the lower body including a distal end that is not encompassed by the upper body;

a first chamber positioned between the upper body and lower body, a second chamber positioned between the upper body and lower body and between the first chamber and the distal end of the lower body, the first chamber being configured to aid in creating a force to decouple the upper body from the lower body, the second chamber being an atmospheric chamber;

a rupture disc that is configured to seal the first chamber, wherein the first chamber is configured to be flooded responsive to the rupture disc breaking to create a piston area within the first chamber, the piston area and the flooded first chamber being configured to assist in the movement of the lower body relative to the upper body.

2. The tool of claim 1 , further comprising:

a wet chamber configured to encompass an annulus positioned between an outer diameter of the tool and a geological formation.

3. The tool of claim 2 , wherein the lower body includes ports that are configured to no longer be encompassed by the upper body and be exposed to the geological formation responsive to the upper body and lower body no longer being coupled together at the first location.

4. The tool of claim 3 , wherein the ports are configured to create a dynamic opening allowing communication into the geological formation based on a change to a relative positioning of the lower body and the upper body caused by a change in applied pressure or force.

5. The tool of claim 4 , wherein a distance between the distal end of the lower body and a distal end of the upper body increases responsive to increasing the pressure within the tool such that a size of the dynamic opening changes, the dynamic opening being configured to allow communication into the geological formation.

6. The tool of claim 1 , further comprising:

a weak point that is configured to couple the upper body and the lower body, wherein the weak point is configured to sever the lower body from the upper body upon increasing the pressure within the tool.

7. The tool of claim 1 , wherein the lower body is configured to be encompassed by the upper body when the upper body and the lower body are coupled together at the first location, and the lower body is configured to be completely exposed to a geological formation when the upper body and the lower body are not coupled together at the first location.

8. The tool of claim 1 , further comprising:

additional tools coupled to the lower body, wherein the additional tools are configured to move downhole along with the lower body when the lower body and the upper body are not coupled together at the first location.

9. The tool of claim 1 , wherein cement is pumped through the tool before fracturing fluid is pumped through the tool.

10. The tool of claim 1 , further comprising:

wherein the first chamber is an atmospheric chamber before the rupture disc ruptures.

11. A method utilizing a tool comprising:

temporarily coupling an upper body to a lower body at a first location while in a first position, the lower body including a distal end that is not encompassed by the upper body;

disengaging the upper body from the lower body at the first location while in a second position,

pumping directly into a geological formation without restriction responsive to disengaging the upper body from the lower body,

forming a first chamber between the upper body and lower body;

forming a second chamber positioned between the upper body and lower body and between the first chamber and the distal end of the lower body, the second chamber being an atmospheric chamber;

sealing the first chamber via a rupture disc;

flooding the first chamber responsive to the rupture disc breaking to create a piston area within the first chamber, the piston area and the flooded first chamber being configured to assist in the movement of the lower body relative to the upper body

creating a force via the first chamber to decouple the upper body from the lower body.

12. The method of claim 11 , further comprising:

forming a wet chamber to encompass an annulus positioned between an outer diameter of the tool and a geological formation.

13. The method of claim 12 , further comprising:

exposing ports within the lower body to no longer be encompassed by the upper body and the geological formation responsive to the upper body and lower body no longer being coupled together at the first location.

14. The method of claim 13 , wherein the ports are configured to create a dynamic opening allowing communication into the geological formation based on a change to a relative positioning of the lower body and the upper body caused by a change in applied pressure or force.

15. The method of claim 14 , further comprising:

increasing a distance between the distal and of the lower body and a distal end of the upper body responsive to increasing the pressure within the tool such that a size of the dynamic opening changes, the dynamic opening being configured to allow communication into the geological formation.

16. The method of claim 11 , further comprising:

coupling the upper body and the lower body via a weak point,

severing the lower body from the upper body upon increasing the pressure within the tool and breaking the weak point.

17. The method of claim 11 , further comprising:

encompassing the lower body by the upper body when the upper body and the lower body are coupled together at the first location, and completely exposing the lower body to a geological formation when the upper body and the lower body are not coupled together at the first location.

18. The method of claim 11 , further comprising:

coupling additional tools to the lower body;

moving the additional tools downhole along with the lower body when the lower body and the upper body are not coupled together at the first location.

19. The method of claim 11 , further comprising:

pumping cement through the tool before fracturing fluid is pumped through the tool.

20. The method of claim 11 , wherein the first chamber is an atmospheric chamber before the rupture disc ruptures.
