3. Saudi Arabian petroleum resources

5. Onshore wells = costs range from $15 million for deep and difficult wells Deepwater drilling rig rates in 2010 were about $420,000/day * a deep water well of duration of 100 days can cost around US$100 million (can be in water almost 2.5 km deep)

38. “Fracking”- Hydraulic Fracturing – a way of retrieving natural gas from shale layers

40. “Fracking”- Hydraulic Fracturing: Environmental Concerns

41. “Fracking” Earthquakes: Wastewater injected into the Ozark aquifer of Arkansas leaked into a deeper unknown fault. The heightened water pressure in the fault relieved just enough of the squeeze on the fault to allow earthquakes.

48. Methane Gas Hydrates:

50. Methane gas hydrate forming below a rock overhang at the sea floor on the Blake Ridge diapir. This image, taken from the DSV Alvin during the NOAA- sponsored Deep East cruise in 2001, marked the first discovery of gas hydrate at the sea floor on the Blake Ridge. Methane bubbling out of the sea floor below this overhang quickly “freezes,” forming this downward hanging hydrate deposit, dubbed the "inverted snowcone."

60. Trying to bring methane gas hydrates to the surface

61. Methane Gas Hydrates Technical problems with retrieving methane clathrates: (a) Although the total gas amounts are huge, most natural hydrate represents a quite low energy density (b) Substantial latent heat must be provided for dissociation (c) The sediments are often fine grained, unconsolidated, and low permeability silts. (d) Turns to gas as it is brought to the surface.
