Davidson Chairman & CEO Noble Energy, Inc. "Technology Impacts on Global Energy Supplies" April 21, 2011 3:30 - 4:30 p.m. FRNY G140 Abstract:

From deepwater basins far offshore to the heart of legacy producing fields, new supplies of oil and gas are being identified and developed. Perhaps this is best exemplified by the recent evolution of shale gas in the United States which has helped to grow our natural gas resources to an estimated 100 years of supply, virtually eliminating the need for natural gas imports. This Centennial Seminar presentation discusses how new and evolving exploration and production technologies such as horizontal drilling, deepwater production systems and geophysics are allowing the oil and natural gas industry to efficiently meet the energy needs in the coming decades.
