Methane Hydrates: Major Energy Source for the Future or Wishful Thinking?

“…1 The Sagavanirktok Formation also includes the West Sak and Ugnu sands, which are estimated to contain from 26 to 44 billion barrels of in-place heavy oil. 1,11 Many of the wells have multiple gas-hydrate-bearing units, with individual occurrences ranging from 10-to 100-ft [3-to 30-m] thick. Most of the well-log-inferred gas hydrates occur in six laterally continuous sandstone and conglomerate units as shown in Figure 10(b).…”

Economics and Resource Uncertainty: The 1002 Area of the Arctic National Wildlife Refuge

“…These volumes were projected annually using field production forecasts and a water cut function (13). As fields are depleted the water cut increases, thereby increasing the per barrel cost of oil.…”
