At Deimos Field in the deepwater Gulf of Mexico, surface seismic imaging cannot fully image sedimentary structure near the steeply dipping base of salt. 3D vertical seismic profile (VSP) imaging was introduced to the deepwater GOM to improve seismic

Pore pressure in sediments beneath salt in the Gulf of Mexico varies widely creating a potentially dangerous and difficult drilling challenge. Estimating elastic parameters of sediments beneath salt is key to the prediction of pore pressure and reduc

Seismic interferometry has become a technology of growing interest for imaging borehole seismic data. We demonstrate that interferometry of internal multiples can be used to image targets above a borehole receiver array. By internal multiples, we ref

Interferometric migration of free-surface multiples in vertical-seismic-profile (VSP) data has two significant advantages over standard VSP imaging: (1) a significantly larger imaging area compared to migrating VSP primaries and (2) less sensitivity

Multiples contain valuable information about the subsurface, and if properly migrated can provide a wider illumination of the subsurface compared to imaging with VSP primary reflections. In this paper we review three different methods for migrating m

VSP or vertical seismic profile was originally designed and is currently primarily used to give us time-to-depth for seismic-well ties. Beyond time-to-depth a number of possibilities exist. Recently, there has been considerable interest in VSP imagin

A deviated borehole was drilled and completed to test systems for deployment of permanent in-well three-component fiber-optic seismic sensors. Two systems were developed and tested for deployment of these sensors. The first system involved using a pa

Multiples have traditionally been considered coherent noise, and so much effort has been put into developing dereverberation algorithms. However, our point of view is that multiple reflection energy can often provide better illumination of the subsur
