Abstract

A separable tool including a mill section, a mill face disposed on the mill section and having a bore therethrough that is offset from a longitudinal axis of the mill section, a tool adapter section, and a release configuration releasably securing the mill section to the tool adapter section with the mill face disposed between the mill section and the tool adapter section. A method for operating a wellbore system including in a single run, setting a plug in the wellbore system, releasing the plug, pumping cement, dressing the cement, and testing the cement.

First claim

What is claimed is:

1. A method for operating a wellbore system comprising:
setting a plug in the wellbore system;
releasing the plug;
pumping cement;
dressing the cement; and
testing the cement, wherein the setting, releasing, pumping, dressing, and testing are all performed in a single run.

2. The method as claimed in claim 1 wherein the releasing the plug is by hydraulic pressure or by overpull.

3. The method as claimed in claim 2 wherein releasing the plug comprises releasing the plug from a Bottom Hole Assembly (BHA) and spacing the BHA away from the plug.

4. The method as claimed in claim 3 wherein the pumping includes filling of a space left by the spacing.

5. The method as claimed in claim 1 further comprising tagging the cement prior to and after dressing the cement.

6. The method as claimed in claim 1 wherein the testing is setting down weight on the cement.

7. The method as claimed in claim 1 further comprising operating one or more of a casing cutter, a casing spear, a pulling tool, a casing anchor, packoffs and casing sealing tools, a punch and wash tool, a perf and wash tool, and valves associated with any of these, and combinations of tools including any of the foregoing.

8. The method as claimed in claim 1 including deploying a separable tool comprising:
a mill section;
a mill face disposed on the mill section and having a bore therethrough that is offset from a longitudinal axis of the mill section;
a tool adapter section; and
a release configuration releasably securing the mill section to the tool adapter section with the mill face disposed between the mill section and the tool adapter section.
