| 摘要 |
A method for mapping remaining hydrocarbon resources in a subsurface reservoir, includes obtaining a map of seismic amplitude difference over a time period based on a survey of the subsurface reservoir, generating an expected trend dataset for the reservoir based on one or more non-water saturation effects detected over the time period by one or more wellbore surveillance techniques at one or more locations in the reservoir, correcting the map of seismic amplitude difference, at least in part, on the expected trend dataset to generate a corrected seismic amplitude map, and using the corrected seismic amplitude difference map to generate a map representative of remaining hydrocarbon resources in the reservoir. Embodiments include a system for performing the method and a medium containing computer executable software instructions for performing the method. |
