Low-Frequency Seismic Imaging of an Unproduced Oil Reservoir in Egypt

A low frequency (LF) passive seismic survey was acquired in Egypt over a discovered but unproduced oil reservoir. Sixty hours of synchronous data were recorded on an array of stations in several lines over the oil discovery and adjacent prospects. The survey was designed for the implementation of 3D Time-Reverse Imaging (TRI) in data processing. Quiet portions of the recorded wave field refocused in the subsurface at the discovery well and several of the prospective surrounding fault blocks. The TRI data volume was loaded and interpreted on a G&G workstation using a work flow developed to rigorously analyze this unique new data type.
