3-well Case Study, Atascosa County, Texas
Milling plugs left in the well by the competition
Casing 5 ½” 23 lb.
PBTD – 15,621′
2” CT Unit
29 8K plugs
Our competition was on the well and unable to reach bottom with their downhole coil agitation tool. They had friction lock up at 14,315’ while pumping 10bbl ultra-lube slugs (2.5 gal per bbl.) every 50 bbl and running 1½ gal per 10 bbl during the operation. 5 plugs were left in the bottom 1000′ of the well. OSES was asked to rig up with the Tempress® HydroPull™. A 40 bbl ultra-lube slug was pumped at 11,150’. At 14,506′ our running weight was 7K. We tagged plugs at 14,578’, 14,794’, 15,013’, 15,242’, and the last plug at 15,471’. Another slug was pumped at 15,246’, and beca-lube at 2qt per 10 bbl. The average drill time on the plugs was 5 min. and wash time between plugs was 21.4 min. We finished the well with 8K running weight at 10 fpm. The total time from RIH to POOH on this job was 5½ hrs
The 2nd well on this pad had similar results with the competition leaving 6 plugs. OSES rigged up with the HydroPull® and reached bottom with the same reduction of chemicals and ending with a 5K running weight at 7 to 10 fpm.
OSES rigged up from the get go on the 3rd well on the pad and we drilled all 29 plugs plus a kill plug with positive running weight, less stall, lower chemical used, and saving ½ day on the overall operation.
