Enhanced oil recovery (EOR) operations promise to increase the yield of existing reservoirs of oil and gas. The USGS estimates there are more than 300 billion bbl oil "locked in" the continental US alone. One of the most promising tools that helps "unlock" these reserves is cross-well seismic tomography. This technique, in essence, consists of seismic sources in one well, data collection by receivers in an adjacent well, and data analysis via tomography to determine interwell lithology which, in turn, can be used to design/modify a steam or fire flood EOR operation.
