“…The legacy near surface model based on an intercept-time method proved to provide the most stable medium to long wavelength solution, followed by iterative residual statics. The controlled amplitude and phase processing workflow included model based wavelet processing (MBWP) (Hart, Hootman, and Jackson, 2001), inverse Q filtering, and robust surface consistent deconvolution (Hootman, 2011) that utilized an advanced simultaneous Jacobi decomposition with an over-relaxation algorithm. This technique combines robust surfaceconsistent deconvolution, surface-consistent amplitude correction, and noise attenuation in one pass to provide relative amplitude preserved data.…”

In 2010, a 100,000 channel point receiver acquisition system was mobilized together with 24 80,000 lb vibrators to improve the characterization of both conventional and unconventional reservoir properties. Using a low frequency sweep design with productivity rates exceeding 8,000 vibration points (VPs) per 24 hours significantly increased the seismic data volume and data rate. Over 6 Tb of seismic data were routinely acquired with critical quality control decision points to maintain the integrity and manage the significant increase in seismic data volume. To ensure that full azimuth signal amplitudes were preserved for all offsets and azimuths, carefully selected true amplitude processing parameters were applied. We present this case history and lessons learned, from this Saudi Arabia project, as part of an ongoing fully integrated broadband acquisition-to-rock mechanics interpretation project.

“…Such methods use simple solvers such as a least-square or a rough approximation scheme, which could be easily biased by high-amplitude surface-inconsistent noise and results in rather poor decomposition. The robust surface consistent deconvolution (RSCD) methodology is applied to address the problem of a biased operator based on a statistically robust L1/L2 norm constrained solver (Hootman, 2011). This robust solver can detect the surface-inconsistent outlier spectra during the decomposition step and then lower the weights of those traces so that they have fewer effects on the decomposed spectra.…”

Southern Ordos Basin contains plentiful oil and gas shale resources in the Mesozoic and Upper Paleozoic. It is known that the surface in this region is covered by thick loess layers with severe variations in tomography, thickness and velocity. The adverse surface conditions result in complex statics problems and heavy scattering noise and also cause serious absorption of high-frequency energy. Conventional seismic surveys obtain poor quality seismic data, which could hardly be used to obtain information about gas shale reservoirs. In order to study strong heterogeneous gas shale reservoirs and improve the success rate of horizontal wells, a new 3D seismic survey was acquired in the typical loess plateau area by using the WesternGeco UniQ integrated point-receiver land seismic system. The new survey is designed as full-azimuth, high-density, point-source/point-receiver in order to fully sample the seismic wavefield and avoid the irreversible signal damage caused by conventional field array techniques. By taking advantage of the benefits of UniQ seismic data, targeted data processing sequence is given to resolve the specific complicated statics and noise attenuation problems. Compared with the previously acquired 2D crooked line high-resolution seismic data in the gullies, the result of UniQ seismic data exhibits significant improvement both in the single-to-noise ratio (SNR) and the image quality of target layers. This indicates that the UniQ seismic data will be more feasible to facilitate gas shale characterization.
