## Abstract

A bridge plug with a selectively blocked flow passage is delivered on wireline and pumped down to the desired location and set. A casing pressure test can be performed above the bridge plug while shielding the formation below from excess pressure from the pressure test. To the extent there are producing zones below the bridge plug or adjacent injection wells that could communicate with the borehole, the plug isolates those pressures from below. After the pressure test is completed, a rupture disc is blown in a passage through the bridge plug and flow is then used to deliver completion equipment to a horizontal portion of the borehole and preferably on wireline.

## Claims

### Claim 1

A completion method, comprising:
delivering a plug on a wireline with flow into a borehole;
setting said plug at a desired location where existing formation access into the borehole is isolated on one side of said plug such that a tubular string that isolates the formation on an opposite side of said plug can be pressure tested;
initially raising pressure against an uphole side of said plug in the borehole to a first pressure to conduct a pressure test of the tubular string;
further raising pressure to a higher pressure than said first pressure to remove a barrier from a passage through said plug;
pumping fluid through said passage of the still set plug to deliver at least one tool for another operation on said uphole side of said plug.

### Claim 2 (depends on 1)

The method of claim 1, comprising:
delivering a setting tool with said plug on said wireline.

### Claim 3 (depends on 1)

The method of claim 1, comprising:
removing said wireline after said setting the plug.

### Claim 4 (depends on 3)

The method of claim 3, comprising:
removing said wireline before said initially raising pressure against said plug.

### Claim 5 (depends on 1)

The method of claim 1, comprising:
using a rupture disc as said barrier.

### Claim 6 (depends on 1)

The method of claim 1, comprising:
accomplishing said removing said barrier without mechanical intervention into the borehole.

### Claim 7 (depends on 1)

The method of claim 1, comprising:
performing a treatment operation after said removing said barrier.

### Claim 8 (depends on 1)

The method of claim 1, comprising:
performing a casing pressure test with said initially raising pressure.

### Claim 9 (depends on 7)

The method of claim 7, comprising:
milling out said plug after said treatment operation.

### Claim 10 (depends on 2)

The method of claim 2, comprising:
removing said wireline after said setting the plug.

### Claim 11 (depends on 10)

The method of claim 10, comprising:
removing said wireline before said initially raising pressure against said plug.

### Claim 12 (depends on 11)

The method of claim 11, comprising:
using a rupture disc as said barrier.

### Claim 13 (depends on 12)

The method of claim 12, comprising:
accomplishing said removing said barrier without mechanical intervention into the borehole.

### Claim 14 (depends on 13)

The method of claim 13, comprising:
treating after said removing said barrier.

### Claim 15 (depends on 14)

The method of claim 14, comprising:
performing a casing pressure test with said initially raising pressure.

### Claim 16 (depends on 15)

The method of claim 15, comprising:
milling out said plug after said treating.

### Claim 17 (depends on 16)

The method of claim 16, comprising:
making the body of said plug cast iron.
