Single well seismic imaging (SWSI) has been identified in the petroleum industry as an exciting new technology with significant economic potential, particularly in the Gulf of Mexico. Deploying a seismic energy source and receiver string in a single well will allow imaging with higher resolution than can now be achieved with 3D surface seismic or the crosswell seismic techniques as well as providing the economics of single well (as opposed to crosswell) surveys. In a salt basin environment, such images would guide targeted, low-risk drilling for oil and gas trapped against salt dome flanks, overhangs, and fault surfaces (see above example of the Choctaw salt dome). The technology would also yield valuable data in subsalt environment where surface data are often uninterpretable. In this project, the Lawrence Berkeley National Laboratory along with two other national laboratories and the industry (consisting of members of the salt imaging consortium) have pooled their resources in a cooperative venture to develop the SWSI technology. An important objective of this project is to leverage DOE and industry resources in the expeditious development of this useful tool that will address areas of research most beneficial to the industry as a whole.
