Updating the low frequency model in time-lapse seismic inversion: a case study from a heavy oil steam injection project

Back to Technical Content
In this paper we discuss a workflow to update low frequency models in time-lapse inversion studies. In this workflow we invert the base seismic survey and the difference between base and monitor survey in two separate inversion runs. The production effects are picked on the output of the difference inversion and this information is used to update the low frequency model in the time lapse sense. This approach is applied to time lapse seismic data from a heavy oil field where steam injection is being used for enhanced oil recovery. The inversion results are compared with other available information from the field and a good match can be observed.
