How Many Bakken Wells/Section in Core Bakken? -- North Dakota, USA

Fracking
  • Extends out laterally from the wellbore 500 feet radius
  • Most of the frac energy within 250 feet of the borewell
  • Potential: additional infill wells. Perhaps as many as five infill wells/horizontal

  • Red River
  • Heath/Tyler
  • Ratcliffe
  • Mission Canyon

Remember, on the April dockets, NDIC: as many as 13 infill wells in 1280-acre spacing.

When I started this blog, "we" were looking at a single well in each section and only one pay zone. It is amazing how far "we" have come in two years.

Also,
  • In general, many of the payzones are non-communicating
  • Fracking multiple wells near each other results in a slightly but, apparently, not a significant decrease in production from additional wells
  • Time will tell how this plays out -- all these infill wells and EURs
