Improving Land Subsurface Imaging using Seismic Interferometry

Seismic reflection can provide precise estimates of subsurface structures. To obtain more information on subsurfaces using the same amount data, we first compared reverse time migration (RTM) images obtained from surface seismic profile (SSP), vertical (VSP), and single well (SWP) data for models that included faults with various dips. When were sufficient, SSP, SWP, VSP surveys suitable identifying horizontal structures, structures steep slopes, near wells, respectively. An appropriate interferometry method was selected after considering advantages disadvantages each survey when either SSP or both, an inaccurate velocity model RTM, noise added to data. The estimated RTM observed be improved applied.
