| | Formation Treatment | | Treatment Type: | FRACTURE STIMULATION | | Treatment Date: | 1/17/2018 | Treatment End Date: | 1/17/2018 | | Treatment Summary: | Perforated four Vermejo Coal intervals listed by stage with 4 SPF and 120 degree phasing including Stage 1 - 1,979' - 82', 1,989' - 94' and 2,004' - 06', Stage 2 - 1,813' - 17', Stage 3 - 1,756' - 58' and Stage 4 - 1,532' - 35' and 1,536' - 39 (net - 22' or 88 holes) with Coil Tubing Unit, 2-7/8" coiled tubing to isolate stages and a 70/30 Quality foam frac. A total of 500 gallons of 15% HCl, 115,784 gallons of produced water, 70,524 lbs of 20/40 mesh Premium White Sand and 494,387 scf N2 were pumped. Stage 3 screened out with 2.6 ppg downhole sand concentration. Stage 4 was skipped as NCS tool could not get back down to setting depth.
Perforated six Raton Coal intervals listed by stage with 4 SPF and 120 degree phasing and fraced the six Raton Coal intervals including Stage 5 - 993' - 96', Stage 6 - 894' - 97, Stage 7 - 804' - 07' and 830 - 34', Stage 8 - 755' - 759', Stage 9 - 712' - 16' and Stage 10 - 654' - 58' (net - 25' or 100 holes) with Coil Tubing Unit, 2-7/8" coiled tubing to isolate stages and a 70/30 Quality foam frac. A total of 250 gallons of 15% HCl, 112,143 gallons of produced water, 151,293 lbs of 20/40 mesh Premium White Sand and 425,825 scf N2 were pumped. All six Raton Coal stages were pumped according to prognosis.
The CTU rigged down and moved to next loaction. Well was cleaned out to PBTD and returned to production as a commingled Raton-Vermejo Coal well. | | Total fluid used in treatment (bbls): | 5444 | Max pressure during treatment (psi): | 3238 | | Total gas used in treatment (mcf): | 920212 | Fluid density (lbs/gal): | 8.35 | | Type Of gas: | NITROGEN | Number Of staged intervals: | 10 | | Total acid used in treatment (bbls): | 17 | Min frac gradient (psi/ft): | 0.52 | | Recycled water used in treatment (bbls): | 5427 | Total flowback volume recovered (bbls): | | | Fresh water used in treatment (bbls): | 0 | Disposition method For flowback: | DISPOSAL | | Total proppant used (lbs): | 221817 | Green completions techniques utilized: | Yes | | Reason green techniques Not utilized: | | Formation Treatment | | Treatment Type: | FRACTURE STIMULATION | | Treatment Date: | 7/5/2012 | Treatment End Date: | 7/5/2012 | | Treatment Summary: | Pumped 4,000 gals 15% HCl acid.
