Summary
The current paper complements the Moridis et al. (2009) review of the status
of the effort toward commercial gas production from hydrates. We aim to
describe the concept of the gas-hydrate (GH) petroleum system; to discuss
advances, requirements, and suggested practices in GH prospecting and GH
deposit characterization; and to review the associated technical, economic, and
environmental challenges and uncertainties, which include the following:
accurate assessment of producible fractions of the GH resource; development of
methods for identifying suitable production targets; sampling of
hydrate-bearing sediments (HBS) and sample analysis; analysis and
interpretation of geophysical surveys of GH reservoirs; well-testing methods;
interpretation of well-testing results; geomechanical and reservoir/well
stability concerns; well design, operation, and installation; field operations
and extending production beyond sand-dominated GH reservoirs; monitoring
production and geomechanical stability; laboratory investigations; fundamental
knowledge of hydrate behavior; the economics of commercial gas production from
hydrates; and associated environmental concerns.
