EAGE E-Lecture: Watching Gas Move: Seismic 4D Reservoir Monitoring of the Pluto Gas Field, North West Shelf of Australia (by André Gerhardt)
This E-Lecture: “Watching Gas Move: Seismic 4D Reservoir Monitoring of the Pluto Gas Field, North West Shelf of Australia”, whilst Seismic 4D monitoring is a mature and established technology commonly used in the reservoir management of oil fields, not much has been published on its use for monitoring gas fields. In this presentation I describe in detail the various steps undertaken in the feasibility studies that underpinned the 4D seismic monitoring of the Pluto Gas Field in the North West Shelf of Australia. I also present some of the results of the first monitor survey which show remarkable similarity with the expectations from the feasibility studies. We postulate that the production-related (pressure and saturation) effects are much easier to predict and quantify when sufficient aquifer support is present.
