چکیده
A major challenge for the oil and gas industry is expediting exploration geophysics activity. It necessary to produce fast accurate image of targeted hydrocarbon reservoir, yet it involves extensive dataset due target location lies in deeper subsurface. Therefore, target-oriented gas-reservoir imaging currently seen as more attractive than conventional full-volume migration, terms computation efficiency. Through integration seismic redatuming with Kirchhoff we presented a workflow that can effectively reduce computational cost while simultaneously enhancing accuracy migrated image. migration renowned being one simplest flexible techniques, making straightforward implement. However, this approach typically avoided presence complex geology, tends introduce artifacts images, thereby disrupting interpretation beneath overburden. paper highlighted advantages utilizing retrieve data overburden, followed by utilization redatumed input migration. With an improved signal noise ratio, primary reflection events were amplified, providing clearer representation subsurface structure within reservoir or area. Additionally, utilized benefits explored feasibility performing patch-based several areas interest salt layer. This aimed both turnaround time associated costs. The developed then was subsequently put test applied sub-salt SEG Advanced Modeling (SEAM) model field situated East Malaysia. Based on outcomes proposed methodology demonstrated its capability generate better quality instant images designated region. Furthermore, substantiated through redatuming, resulting significant towards processing, imaging, interpretation.

prestack time migration of 2d seismic records by the kirchhoff method
in exploration seismology, migration refers to a multi-channel processing step that attempts to spatially re-position events and improve focusing. before migration, seismic data is usually displayed with traces plotted at the surface location of the receivers and with a vertical time axis. this means that dipping reflections are systematically mispositioned in the lateral coordinate and the ver...
متن کاملTerahertz reflection imaging using Kirchhoff migration.
We describe a new imaging method that uses single-cycle pulses of terahertz (THz) radiation. This technique emulates data-collection and image-processing procedures developed for geophysical prospecting and is made possible by the availability of fiber-coupled THz receiver antennas. We use a simple migration procedure to solve the inverse problem; this permits us to reconstruct the location and...
متن کاملTarget-enclosed seismic imaging
Seismic reflection data can be redatumed to a specified boundary in the subsurface by solving an inverse (or multidimensional deconvolution) problem. The redatumed data can be interpreted as an extended image of the subsurface at the redatuming boundary, depending on the subsurface offset and time. We retrieve targetenclosed extended images by using two redatuming boundaries, which are selected...

A seismic processing workflow based on iterative ray+Born migration/inversion and targetoriented post-processing of the migrated image is developed for fine-scale quantitative characterization of reflectors. The first step of the workflow involves linear iterations of the ray+Born migration/inversion. The output of the first step is a true-amplitude migrated image parameterized by velocity pert...
