Abstract
Methods and systems for historical, geological modeling for producing an estimated distribution of hydrocarbons trapped in subsurface clathrates are disclosed. One method includes instantiating a basin model of a geological area of interest, and, for each of a plurality of predetermined geological times up to a geologic present day: determining one or more changes to the basin model, calculating, at each of a plurality of locations within the basin model, a temperature and a pressure, determining an existence and a location of a clathrate stability zone based on the calculated temperatures and pressures, and estimating one or more clathrate concentrations and hydrocarbon volumes in the clathrate stability zone. The method further includes calibrating a present day clathrate concentration and hydrocarbon volume derived from the basin model against calibration data obtained from one or more locations within the geological area of interest, thereby providing a model of the present day clathrate concentration and hydrocarbon volume at each of the plurality of locations.
