This article reviews some key aspects of two important branches in unsupervised signal
processing: blind deconvolution and blind source separation (BSS). It also gives an …

Dispersion and attenuation corrections can improve the resolution of seismic data. This
significantly facilitates interpretation. In principle, inverse Q filtering and the time-varying …

Abstract Characterization of geothermal reservoirs is an important step for exploration and
development of geothermal energy, which is reliable and sustainable for the future. Based …

In contrast to the use of marine seismic reflection techniques for reservoir‐scale
applications, where seismic inversion for quantitative sediment analysis is common, shallow …

We evaluated a semiautomatic method for well-to-seismic tying to improve correlation
results and reproducibility of the procedure. In the manual procedure, the interpreter first …

The Radon transform (RT) plays an important role in seismic data processing for its ability to
focus seismic events in the transform domain. The band-limited nature of seismic events due …

Phase mismatches sometimes occur between final processed seismic sections and zero-
phase synthetics based on well logs—despite best efforts for controlled-phase acquisition …

Abstract Abu Gharadig Field lies in the central portion of Abu Gharadig Basin of the northern
part of the Western Desert of Egypt, about 256 km west of Cairo. Abu Gharadig Basin is …

Tying the synthetic trace to the actual seismic trace at the well location is a labor-intensive
task that relies on the interpreter's experience and the similarity metric used. The traditional …

In this work, we applied a Bayesian time-lapse (4D) seismic inversion to a deep-water heavy
oil field located in the Campos Basin (Brazil). In this procedure, the differences of seismic …
