A total of 1,500 gallons 15% HCl, 157,987 gallons of produced water, 157,003 lbs of 20/40 Premium White Sand and 569,743 scf N2 were pumped. Stage 3 was skipped due to backside pressure. Stage 7 was skipped as the isolation tool could not get back to depth. NCS tool left in the hole with top at 1,884' GL. Removal of tool will be attempted at a later date.
Perforated eight Raton Coal intervals listed by stage with 4 SPF and 120 degree phasing and fraced the eight Raton Coal intervals including Stage 9 - 1,086' - 93', Stage 10 - 1,008' - 15', Stage 11 - 982' - 988', Stage 12 - 982' - 88', Stage 13 - 850' - 857', Stage 14 - 700' - 709', Stage 15 - 674' - 682' and Stage 16 - 638' - 641' amd 652' - 654' (net - 54' or 216 holes) with Coil Tubing Unit, 2-7/8" coiled tubing to isolate stages and a 70/30 Quality foam frac. A total of 1,000 gallon of 15% HCl, 147,991 gallons of produced water, 218,927 lbs of 20/40 mesh Premium White Sand and 708,702 scf N2 were pumped. Stage 9 was prematurely shutdown due to an erroneous Halliburton pressure transducer indicating backside pressure was increasing rapidly. The pressure transducer was subsequently found to be wrong. Stage 11 and 13 were skipped due to backside pressure increasing on previous stages.
The CTU was rigged down and moved to the next location. Well was cleaned out to top of tool at 1,884'. LD 2-7/8" tubing and returned to production as a commingled Raton - Vermejo coal well flowing up casing. | | Total fluid used in treatment (bbls): | 7344 | Max pressure during treatment (psi): | 2939 | | Total gas used in treatment (mcf): | 1278445 | Fluid density (lbs/gal): | 8.35 | | Type Of gas: | NITROGEN | Number Of staged intervals: | 16 | | Total acid used in treatment (bbls): | 59 | Min frac gradient (psi/ft): | 0.47 | | Recycled water used in treatment (bbls): | 7285 | Total flowback volume recovered (bbls): | | | Fresh water used in treatment (bbls): | 0 | Disposition method For flowback: | DISPOSAL | | Total proppant used (lbs): | 375930 | Green completions techniques utilized: | Yes | | Reason green techniques Not utilized: | | Formation Treatment | | Treatment Type: | | | Treatment Date: | 1/23/2014 | Treatment End Date: | 2/19/2014 | | Treatment Summary: | XTO squeezed off only the perfs fr/506'-545' in this formation on 02/19/2014 with 119 sx Type B cmt.
