The Wamsutter area has both a prolific past and a bright future. It contains an abundance of gas trapped in low permeability Cretaceous sandstones of the Almond and Lewis Formations which requires fracture stimulation for production. The year 2001 was active and productive. BP drilled a total of 92 wells, bring the BP-operated total to over 500. BP-operated daily production for 2001 was approximately 300 MMCFD. Effective team work, cost management, technology and safety are key to these results. In 2002, aggressive performance targets continue. Forward planning for Wamsutter development emphasizes selective prospecting, well performance prediction, effective completions and effective use of the existing infrastructure. The goal of no-harm-to-the-environment continues to be a high priority for all of BP operations. The Wamsutter area is maintaining its status as a prolific North American gas province.
