Assessment of offshore methane clathrate hydrate


Methane hydrate, an ice-like substance, occurs offshore in sediment under sea water depths of greater than 500m at temperatures of 0-20 degrees celcius. Hydrate is a non-stochiometric mixture of methane and water. Methane from hydrate is a possible intermediate resource and a greenhouse gas. Physically, it is electrically more resistive than native sediment and can be mapped using novel electromagnetic transient methods at the diffusive limit. We have invented methodolgies, designed field procedures through relevant theory and numerical modelling and conducted successful experiments at sea worldwide.
