Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 15–18, 2021
Paper Number: SPE-207719-MS
.... Stratigraphic traps are challenging the seismic resolution but the denser spatial sampling of that pilot survey was the way to reveal such tiny features with good image clarity. The qualitative way of seismic interpretation was completed showing added values for having ultra-dense spatial sampling acquisition...

... reservoir development. Current machine-learning methods have been widely used in exhaustive spatial data sets like satellite images. However, geological subsurface characterization is significantly different because it is conditioned by sparse, nonrepresentative sampling. These sparse spatial data sets...

... applied “Mid-night operation” and “High-dense spatial sampling”. Prior to the seismic survey, we monitored surface noise for several days to understand the spatial and chronal noise change in the survey area. Based on the noise monitoring result, we shot in night time as much as possible in order to avoid...

... in the offset-time domain. The impact of random spatial sampling on internal multiple prediction is tested in this domain. This study is carried out on both a two-interface synthetic model and a physical modeling dataset recorded in the CREWES Physical Modeling Facility. We find that the 1.5D version...

... effectiveness gabor deconvolution Summary A recent trend in seismic data acquisition is the deployment of receivers and/or sources at increasingly smaller surface station intervals. Two coupled objectives for this decreased spatial sampling are more effective coherent noise attenuation, and higher...

... Summary Sampling theory is one of the basic foundations of geophysics. The spatial sampling criteria for classical marine seismic acquisitions are well known, and can be considered a solved problem. Modern acquisition practice uses very fine receiver group spacing and dense coverage, and spatial aliasing...
