A Probablistic Approach to Shale Gas Economics

SPE 108053

Shale gas plays are generally characterized by high commercial risk. The economic evaluation process requires a consistent approach in comparing the economics of various plays, defining a range of uncertainties, and providing management with maximum insight into the basis for a Go—No Go decision.
