Size:
- There are 77.5 sections in that oil field
- 76 are 640-acre sections (or thereabouts)
- 3 are half-sections (320 acres or thereabouts)
- Total: 49,600 acres
- A rectangle of 10 sections by 8 sections would be 80 sections
- A section is a mile x a mile
- Therefore, if the field were a perfect rectangle, it would be about 10 miles x 8 miles.
- there are six 320-acre spacing units
- there are ten 640-acre spacing units
- other than the 320-acre units and the 640-acre units, the rest are 1280-acre units
- it appears most of the field is also spaced with overlapping 2560-acre units
49,600 acres / 294 wells = one well for every 168.71 acres, or about four wells for every section, or eight wells in every 1280-acre spacing unit.
Monthly production in most recent report: 1,395,082 bbls/month, or 46,502 bopd.
1,395,082/294 = 4,745 bbls//month/well.
