A total of 750 gallons of 15% HCl, 86,640 gallons of produced water, 110,289 lbs of 20/40 mesh Premium White Sand and 643,729 scf N2 were pumped. Stage 5 and Stage 7 were pumped according to prognosis. Stage 5 pumped according to prognosis. Stage 6 could not be broke down and was skipped. Stage 7 fraced pumped according to prognosis.
The CTU rigged down and moved to next location. Well was cleaned out to PBTD and returned to production as a commingled Raton-Vermejo Coal well. | | Total fluid used in treatment (bbls): | 6161 | Max pressure during treatment (psi): | 3447 | | Total gas used in treatment (mcf): | 1458544 | Fluid density (lbs/gal): | 8.35 | | Type Of gas: | NITROGEN | Number Of staged intervals: | 7 | | Total acid used in treatment (bbls): | 17 | Min frac gradient (psi/ft): | 0.51 | | Recycled water used in treatment (bbls): | 6144 | Total flowback volume recovered (bbls): | | | Fresh water used in treatment (bbls): | 0 | Disposition method For flowback: | DISPOSAL | | Total proppant used (lbs): | 247584 | Green completions techniques utilized: | Yes | | Reason green techniques Not utilized: | | Formation Treatment | | Treatment Type: | | | Treatment Date: | 8/16/2012 | Treatment End Date: | 8/21/2012 | | Treatment Summary: | New number of perforations due to Remedial O2 Zone Isolation on perfs fr/594'-597'. | | Total fluid used in treatment (bbls): | | Max pressure during treatment (psi): | | | Total gas used in treatment (mcf): | | Fluid density (lbs/gal): | | | Type Of gas: | | Number Of staged intervals: | | | Total acid used in treatment (bbls): | | Min frac gradient (psi/ft): | | | Recycled water used in treatment (bbls): | | Total flowback volume recovered (bbls): | | | Fresh water used in treatment (bbls): | | Disposition method For flowback: | | | Total proppant used (lbs): | | Green completions techniques utilized: | -- | | Reason green techniques Not utilized: | | Formation Treatment | | Treatment Date: | 3/8/2006 | | Treatment Summary: | ACIDIZED W/2,682 GALS 15% HCL ACID.
