METHOD OF DETECTING A LATERAL BOUNDARY OF A RESERVOIR

摘要

A method of monitoring a subsurface formation underneath a sea bed, the method comprising determining non-vertical deformation of the sea floor over a period of time and inferring a parameter related to a volume change in the subsurface formation from the non-vertical deformation of the sea. Determining the non-vertical deformation of the sea floor comprises selecting a plurality of locations on the sea floor and determining a change in distance between at least one pair of the locations over the period of time.
