Wamsutter, A Giant Tight Gas Field: Reservoir Management at a 50 mile by 50 mile scale

Wamsutter is a giant tight gas field covering a 50 square<br>mile area located in Wyoming, USA. The Wamsutter<br>Field contains an estimated 50 trillion cubic feet (TCF) of<br>Gas Initially in place (GIIP). Discovered in the late<br>1950s, it has to date produced roughly 2 TCF of natural<br>gas and gas equivalent from low permeability (0.01 mD)<br>sandstone reservoirs. BP has a large acreage position<br>in Wamsutter and drills over 100 wells per year in order<br>to efficiently recover field-wide reserves.
