| | Formation Treatment | | Treatment Type: | FRACTURE STIMULATION | | Treatment Date: | 1/21/2018 | Treatment End Date: | 1/22/2018 | | Treatment Summary: | Perforate five Vermejo Coal intervals with 4 SPF and 120 degree phasing listed by stage and fraced five Vermejo Coal intervals including Stage 1 - 1,933' - 37' and 1,940' - 42', Stage 2 - 1,883' - 85', 1,891' -93' and 1,907' - 10', Stage 3 - 1,850' - 54', Stage 4 - 1,642' - 45', Stage 5 - 1,586' - 89' and 1,597' - 98' (24' net or 96 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, 138,026 gallons of produced water, 116,367 lbs of 20/40 mesh Premium White Sand and 645,493 scf N2 were pumped. Stage 4 screened out with 1.0 ppg sand downhole concentration.
Perforate four Raton Coal intervals with 4 SPF and 120 degree phasing listed by stage and fraced four Raton Coal intervals including Stage 6 - 752' - 58' and 771' - 777', Stage 7 - 677' - 82', 695' - 698' and 700' - 02', Stage 8 - 628' - 32' and Stage 9 - 565' - 67' and 579' - 81' (net - 30' or 120 holes) with Coil Tubing Unit and 2-7/8" coiled tubing to isolate stages. A total of 177,726 gallons of produced water, 251,542 lbs of 20/40 mesh Premium White Sand and 580,386 scf N2 were pumped. All four stages were pumped according to prognosis.
In addition, TCE perforated three intervals with 4 SPF and 120 degree phasing that were not fraced. The three Vermejo Coal intervals were 1,809' - 14', 1,816' - 25' and 1,828' - 31' (net 17' or 68 holes). The intervales were not fraced.
The CTU rigged down and moved to next location. Well was cleaned out to PBTD and returned to production as a commingled Raton-Vermejo well. | | Total fluid used in treatment (bbls): | 7529 | Max pressure during treatment (psi): | 3730 | | Total gas used in treatment (mcf): | 1225779 | Fluid density (lbs/gal): | 8.35 | | Type Of gas: | NITROGEN | Number Of staged intervals: | 9 | | Total acid used in treatment (bbls): | 11 | Min frac gradient (psi/ft): | 0.54 | | Recycled water used in treatment (bbls): | 7518 | Total flowback volume recovered (bbls): | | | Fresh water used in treatment (bbls): | 0 | Disposition method For flowback: | DISPOSAL | | Total proppant used (lbs): | 367909 | Green completions techniques utilized: | Yes | | Reason green techniques Not utilized: | | Formation Treatment | | Treatment Date: | 2/5/2007 | | Treatment Summary: | ACIDIZED W/ 3250 GALS 15% HCL FRACD W/ 202.283 GALS 20# DELTA 140 WITH SANDWEDGE OS CARRYING 25,500# 16/30 ARIZONA SAND FOLLOWED BY 42,603# 12/20 ARIZONA SAND |
