The gas-directed rig count from 2000 to 2006 experienced an initial spurt followed by sustained increases. Production generally declined and LNG was widely expected to serve as the only major source of incremental supply until Arctic gas pipelines were completed. Since 2008, both prices and rig counts collapsed while annual production has grown 1.5 to 2.0 billion cubic feet per day. Financial arrangements, horizontal drilling and other procedures in core regions have improved productivity while leasing terms (to hold leases by production) have sustained drilling under falling prices. During 2010, a shift in the mix to oil-rich plays also has contributed to co-product oil and gas production, stabilizing the level of drilling even PLATT as prices continued to decline.
