Capstone: A Tight-Gas Development

A Spacing-and-Economics Problem

An unconventional play is decided by well spacing and economics. Each well drains only its stimulated rock, so adding wells raises the field recovery, but interference makes every new well contribute less while costing the same.

Value, Not Recovery

Field value is the recovered gas minus the drilling and completion cost, and it peaks at a finite well count. Too few wells leave gas behind; too many drill uneconomic wells into rock the neighbors already drain.

Optimize, Then Drill

The decline physics and production forecasting from the previous chapters combine here into the spacing decision that defines an unconventional development.
