Table 5. EROFI and EROI of Federal GoM Ultra-deepwater energy using three different

energy intensity ratios (7MJ/$, 12MJ/$, 18MJ/$) and three different rig count scenario

estimates. MJ/$ = Megajoules/U.S. dollar. All values are inflation adjusted.

Figure 2. Inflation adjusted standard EROI for the Macondo Prospect and 2009

ultra-deepwater total oil plus gas production calculated from EROFI using different energy

intensity ratios. EROI is based on 2005 energy intensity ratios and costs in 2005 dollars.

Error bars reflect potential daily production flow rates for Macondo data and different rig

counts for 2009 data (see text for discussion).
