Some Lapses Of Time-Lapse Feasibility And Interpretation Studies

There are numerous successful applications of seismic monitoring of hydrocarbon production in different types of reservoirs. Even quantitative evaluations of saturation and pressure evolution due to reservoir production can be observed in some case histories. Every 4D study, however, involves some restrictive assumptions related to rock and fluid behavior. This paper discusses some shortcomings of time-lapse feasibility and interpretation studies as well as yields an insight on the possible errors involved.
