High-density development is conducive to pad drilling. In Pinedale field, the operators drill gently S-shaped directional wells from central surface pads. This is a technology that was originally developed for drilling offshore wells from a central platform, but that is now being applied onshore. Wells are arranged in pods of two to eight wells on a pad. Up to 50 wells can be drilled on an individual pad so that the physical footprint of operations and wildlife habitat fragmentation are minimized.

Pad drilling along with timely reclamation has allowed all Pinedale field operators to reduce disturbance of the land. As field development has progressed and the number of wells per pad increased, the disturbance per well has continued to decline. Surface disturbance per well is now less than one acre on some multiwell pads (Figure 5).
