Abstract

A plurality of development scenarios is determined. At least a first well is drilled at a first location and trajectory that are common to the plurality of development scenarios. A result of the at least one first well is assessed. A first subset of development scenarios is selected from the plurality of development scenarios based at least on the result of the first well. A first sequence of subsequent wells, including at least one well, are drilled at a first sequence of subsequent locations and trajectories that are common to the first subset of development scenarios.
