SUGGESTED ROTARY DRILLING TECHNIQUE FOR OWEN BRIDGE PLUGS:

The following is a general guide for the most successful drill-out technique

1. A. Bit - New, medium tooth, hard formation

2. B. Rotary Speed - 80 rpm normal (120 rpm as required)

3. C. Weight on Bit - Apply 5,000 - 7,000# until the top end of the center body of the bridge plug is drilled away (3 - 5 in. for 4-1/2" - 7" plugs and 5 - 7 in. for larger plugs). Additional weight can now be applied across the full bit diameter. The weight increase is 2,000 - 3,000# per inch of bit diameter ( i.e. 4-1/2" bit use 9,000 - 13,500# weight).

4. D. Drill Collars - 8 minimum for 4-1/2" and 5-1/2" plugs -12 or more for 7" and larger plugs - Spudding the workstring and variations in rotary speed and set-down weight should be used to aid in breaking up large metal parts and preventing bit "tracking".

One or more junk baskets should be used above the bit when normal circulation is employed.
