Comparison of 2000, 2002, and 2004 deepwater GOM reports: successive increases in deepwater BOE. The deepwater arena has made great strides in the last few years, establishing itself as an expanding frontier. The previous edition of this report (Baud et al., 2002) documented the advancements made in deepwater exploration and development since 1974. Several notable changes have occurred in the deepwater GOM since the last report. • The deepwater frontier is now in water depths greater than 7,000 ft (2,134 m). • The first exploratory well was drilled in over 10,000-ft (3,048-m) water depth. • The first deepwater well was drilled below 30,000-ft (9,144-m) depth (true vertical depth). • Eleven discoveries were found in over 7,000-ft (2,134-m) water depths. • The deepest production increased from approximately 5,300-ft (1,615-m) water depth (Mensa) to over 7,000-ft (2,134-m) water depth (Camden Hills). • The first deepwater discoveries in the Eastern GOM were found. • There were significant new discoveries in both Walker Ridge and Alaminos Canyon in older, lightly tested Paleogene reservoirs. • Industry has made great technological achievements (e.g., polyester mooring, composite riser, cell spars, and 15,000-psi subsea trees). • Loop currents have been recognized as posing significant design challenges for deepwater structures, rigs, and pipelines. • The average number of operating rigs is down 29 percent and the number of wells drilled is down 37 percent. • Average bid amounts per block have stabilized or decreased slightly. • There was a 51 percent increase in the number of producing deepwater projects. 112
• Nonmajor companies have made more deepwater discoveries and hold more deepwater acreage than the major companies. • Deepwater production rose more than 100 MBOPD and 400 MMCFPD each year since 1997. • Subsea gas production has increased 90 percent since December 2000. Since the start of 2000, new deepwater drilling added over 4.5 billion BOE, a 40 percent increase over the total deepwater BOE discovered from 1974 to 1999. The deepwater GOM continues to increase in its importance to the Nation’s energy supply. The large number of active deepwater leases, the drilling of important new discoveries, the growing deepwater infrastructure, and the increasing deepwater production are all indicators of the expanding frontier. This ensures that the deepwater GOM will remain as one of the world’s premier oil and gas basins. 113
