“…Reflection tomography uses combined direct and reflected arrival tomography for velocity estimation by using reflectors that originate below the region of direct arrival coverage. Along with velocity, a measure of attenuation also can be computed (Carrillo et al, 2007). In crosswell seismic data, several arrivals are present in the recorded wavefield: direct arrivals, compressional and shear reflections from below (upgoing) and above (downgoing) the source and receiver, and various converted modes and tube waves.…”

Crosswell seismic (CS) technology provides a high-resolution image of the subsurface between two nearby wells. Crosswell seismic data can reach frequencies greater than 1000 Hz, which makes the technology applicable to many reservoir-development challenges in hydrocarbon exploration and production studies that require high resolution. Applications of crosswell seismic data range from structural and stratigraphic interpretation to reservoir monitoring and enhanced oil recovery (EOR). When integrated with rock physics, crosswell seismic data can be used in reservoir-characterization studies, which potentially could be used for enhancing the resolution of rock properties derived from 3D surface-seismic data to that of crosswell resolution. In addition, velocity models obtained from crosswell seismic data can be used to better predict event locations in microseismic data processing.

“…Such a study was performed by Carrillo et al (2007). They found that there is a significant attenuation of seismic waves that have passed through the reef, summarized in Figure 37, taken from their publication.…”

“…The high-Q regions above the reef and neighboring the reef correspond to anhydrite and salt layers, respectively. ( Figure 5 from Carrillo et al, 2007. ) We have also investigated the possibility that the quality of the stack for reflected events is degraded when the seismic ray passes through the reef.…”

“…For the estimation part, various approaches have been utilized. These include the use of VSP data (Ma et al, 2004), crosswell seismic data (Carrillo et al, 2007), and surface seismic data, to name a few. Since the former two types of data are not always available because of the cost reason, seismic surface data are often used for estimating Q and spectral ratio approach is one of the widely used methods for this matter.…”

Following our previous work on Amplitude Tomography that deals with amplitudes alone, we extend our effort to include the compensation of bandwidth and phase of seismic signals that are distorted by seismic attenuation. Our new approach involves utilizing tomographic inversion for estimating the quality factor (Q) from prestack depth migrated common image gathers. By filtering the seismic data into different frequency bands and measuring the effect of attenuation on amplitudes in each band, the frequency dependent effect, which was ignored in our previous work, of attenuation is fully taken into account, allowing Q to be estimated from our tomographic method. By using the estimated Q volume in one of the migration methods that incorporates Q in the traveltime computation, we demonstrate, through examples, that our workflow provides an optimal compensation solution that resolves amplitude and bandwidth distortions due to seismic attenuation.
