Exploring the Interwell Reservoir Space with Crosswell Imaging and Interpretation: An Example of Multi Scale Data Integration from Indonesia

Much has written about seismic interpretation and characterisation of the subsurface and until recently, this topic<br>has focused on the traditional techniques such as surface seismic and vertical seismic profiling (VSP). One critical<br>limitation in combining these with well based measurements is the lack of understanding as to what happens to<br>the seismic signal both away from the well and at a finer resolution (reservoir space) than the surface based<br>methods. Crosswell seismic helps to bridge the gap in both directions; log property mapping and upscaling these<br>to field wide scale and seismic property mapping or downscaling surface seismic properties for well correlation.<br>By nature of the measurement, crosswell provides higher resolution images of the interwell region that augments<br>the seismic characterisation of the subsurface.
