I was on site to witness the cementing of the 13 3/8 inch surface casing. My inspection revealed that Sidewinder Drilling Rig # 63 has drilled a 17 1/2 inch hole to a total depth of 1015 feet and ran 1005 feet of 13 3/8 inch surface casing (54.5 pounds per foot / inside diameter 12.615 inches). They installed 8 spiral solid body centralizers on the casing string (on joints 1,3,7,11,15,19,23, and 25). Universal cemented the surface casing with 794 sacks of Type 1 cement with 3% CaCl, 0.2% defoamer, and 1/4 pound per sack lost circulation material. The cement had a density of 15.6 pounds per gallon, a yield of 1.2 cubic feet per sack, and they used 5.2 gallons of mix water per sack. Universal pumped 169 barrels of cement slurry, 150 barrels of displacement, and there was 25 barrels of cement returns to surface. They bumped the plug at 02:13 pm with 495 PSI and then bumped the pressure up to 1025 for the casing test. The casing test was approved at this time and the floats held when the pressure was released. My inspection revealed no violations at this time.

I was on site to witness the cementing of the 9 5/8 inch intermediate casing. My inspection revealed that Sidewinder Rig # 63 has drilled a 12 1/4 inch hole to a total depth of 2305 feet and ran 2295 feet of 9 5/8 inch intermediate casing (40 pounds per foot / inside diameter 8.835 inches). They installed 20 spiral solid body centralizers on the casing string, on joints 1,2,6,10,14,18,22,26,30,34,38,42,46,50,54, 58,62,66,70, and 74. Universal cemented the casing with 705 sacks of Thixotropic cement with 5% W-60, 10% Salt, 2% CaCl, and 0.15% CR3. They pumped 162 barrels of cement slurry, 165 barrels of displacement, and there was 25 barrels of cement returns to surface. They didn't bump the plug because the wiper plug stayed in the Blackhawk cement head. They pumped 165 barrels of displacement out of the 171 barrels of calculated displacement. They finished pumping at 11:15 am, held pressure on the casing for 5 minutes and the floats held after the pressure was released. My inspection revealed no violations at this time.
