1. Clean mixing pit and lines thoroughly leaving no residual mud in the pit or the lines.
2. Add 77 bbls of freshwater, 4 pails of Turbo-Defoamer and 12 pails of EZ Thin to the mixing pit.
3. Add 400 sacks of EZ Squeeze® to the mixing pit and allow agitation until homogenous.
4. Add Barite, if needed, to achieve desired slurry weight.
5. With the bit @ a depth which all of the slurry can exit the bit and 20 bbls of EZ Squeeze® are in the formation, pump the 100 bbls of E Z Squeeze® slurry to the drill pipe with rig pumps at 3-5 bpm to the bit.
6. As the EZ-Squeeze® reaches the bit begin bull heading the slurry out of the bit until all of the 20 bbls of EZ Squeeze® are in the formation of concern. If at any time a significant increase in pressure is achieved prior to bull heading the recommended volumes into the formation of concern, discontinue pumping, open hydril and pump the remaining EZ Squeeze® slurry as a balanced pill, POOH to above the slurry inside casing and circulate an additional 10 bbls of system mud to ensure the DP and BHA are clear of any remaining slurry. TCI never recommends leaving slurry inside the DP w/ a bit w/ jets or any tools. Shut down for 1 hour andmonitor well.
7. Prior to beginning hesitations, check fluid level on backside, if any fluid should be required to fill, obtain accurate fluid volumes required to fill to know the exact location and volume of slurry remaining. Begin hesitations by pumping 5 bbls @ ½ to 1 bpm, every 30 – 45 minutes, until desired pressure is achieved. If
no pressure is obtained upon squeezing half of the remaining EZ Squeeze® volume (50 bbls) into the formation, discontinue pumping and wait one hour. Resume hesitations by pumping 3 bbls @ ¼ – ¾ bpm until desired pressure is achieved or the tail end of the EZ Squeeze® slurry is 3 bbls above the zone of
concern, begin 4 hour wait.
