Welcome to MODEL Software Output
Output -- these are the EPA AERMOD text output files.
Weather data common to all studies - One year (2016) of hourly data
1 -- 1 hr Ave Area highest hourly reading for each of the 144 sensors placed with 36 in each ring at
500 ft, 1,000 ft., 2,500 ft., 5,000 ft.(They are actually 131 meters further than actual from the center
of the pad to match the drawing at 500 and 1000 feet.)
This Area (vs Point) is the area of the pad. The offset when measured,
it is offset from the equipment not the pad edge. So the pad area is the equipment area.
Drilling / Flowback methane at mean of 490.0 grams/sec area from Garfield Table 3.1.
2 -- 1 Same setup as 1 (above) but highest 4 hourly readings for each of the 144 sensors.
3 -- 1 hr Ave area fracking benzene (C6H6) 0.10 grams/sec from Garfield Table 3.2.
Benzene is not listed as one of the components of the 4 wells that are in Township 1North 68West
Sections 15,22,26,and 28. It is listed as "trace" under fracking fluids for Extraction Oil and Gas
in their November 2016 proposal. It is not listed under fracking fluids for Extraction at the
web site: https://FracFocus.org
But Benzene shows up in all the fracking results. I suspect it is a result of the
fracking process and is probably produced by the diesel engines.
4 -- 1 hr Ave area production 0.004719 loss rate per per Anthony J. Marchese (CSU)
5 -- Monthly average area production at 0.47% losses. same data as above in 4 but averaged for the month.
7 -- 1 hr Ave area production 0.004719 loss rate per per Anthony J. Marchese (CSU)
This is identical to Study4 except this is point not area
8 -- 1 hr Ave area production 0.004719 loss rate per per Anthony J. Marchese (CSU)
This is identical to Study7 except using 152.4 304.8 762.0 1524.0 - no 131 m offset
9 -- 1 hr Ave area production 0.004719 loss rate per per Anthony J. Marchese (CSU)
This is identical to Study2 except using variable monthly rates to reflect new wells.
10 -- 1 hr Ave Point at 490.0 g/sec loss rate per Garfield table 3.1 (CSU)
This is point data at 28 meters (92 feet) although it shows in the middle of Sheridan pad
You can see if the loss were from a tank or valve next to 160th it would exceed 5000 ppm (10%LEL). However Lower Explosive Limit is
50,000 where an ignition source (car ignition or cigarette) could be available. Zoom in and click at 30 degrees.
Studies 101 through 108 on FourPads
The internal dates of the studies all reflect 2016 which is the only year of weather data.
The years are changed externally, appended and saved for the proper Drill, Frack, Flowback or Production year for the pad.
The Results can be seen on FourPads and go for 6 years 2016-2021 using 2016 weather data.
Study101_16(Lowell) 36 and 54 g/sec
Study 101_FullYear (Sheridan, United, Huron) Drill Frack Flowback at fixed 54 g/sec.
The Months associated with the Drill Frack and Flowback partial years are pulled out for the months as required.
The data and year are saved for the Drill Frack Flowback year.
Studies 102(Lowell), 104(Sheridan), 106(United), 108(Huron) Production at Variable rates to reflect new wells.

This is a marker on the FourPads screen.
The AERMOD model shows the concentrations from all the processes from all the pads for all the years.
In addition to the studies below, the hourly data is stored in a separate file (not listed below).
As with the above, the weather data is 2016, the files are appended, and the year changed.
Sheridan Pad Cartesian:
Studies 1,3,4,203,303,and 403 show the benefits of drilling, fracking, and flowback in the summer months.
