... ABSTRACT In the petroleum industry, seismic attributes have been used extensively as a tool for prospect identification and reservoir characterization. Therefore, there has been an increased interest in developing more advanced attributes since the 90s. The significant progress in computing...

... ABSTRACT The Pairwise Attribute Independence Table visually displays the statistical independence of all pairs of attributes in an attribute selection list. After discussing different ways to evaluate attributes in the table, three case studies illustrate its utility. One case study concludes...

... Summary The multi-attribute rotation scheme (MARS) is a methodology that uses a numerical solution to estimate a transform to estimate petrophysical properties from elastic attributes. This is achieved by estimating a new attribute in the direction of maximum change of a target property...

... Summary: Effective porosity prediction in 3D space away from the well is essential to characterize reservoir effectively. Precise prediction of effective porosity is a challenging task because of the non-uniqueness in its relationship with conventional seismic attributes. The challenge further...

... reservoirs with relatively limited core analysis data. By integrating the geological attributes and petrophysical properties, a better history match was achieved in the dynamic modelling, which could be used in forecasts and future reservoir management activities. Introduction F Field is located...

... Abstract The objective of this study is to develop and examine a machine learning model that combines multiple seismic attributes in a way that preserves all the features of the combined attributes with, hopefully, better resolution and efficiency than the conventional seismic attributes...

... et al. 2015 ) showed that diffraction attributes could reveal more detailed geological features (Karsts etc.) than post-stack seismic data. In general, diffraction analysis separates diffraction energy (energy scattered from discontinuities in the subsurface) in a seismic volume after muting regular...

... The consistently increasing number of seismic attributes makes the use of every seismic attribute difficult if not impossible. Machine learning algorithms demonstrated a good capability of selecting useful attributes and extracting the maximum of their hidden features. In this study, seismic...

... Seismic coherence is one of the seismic attributes that can be used to aid in seismic fault and stratigraphic interpretation. Traditionally, seismic coherence is computed by measuring the similarity between waveforms of 2D seismic section or 3D seismic volumes. More recently, the computation...

... The ultimate goal of oil and gas exploration is to find hydrocarbons. This search utilizes seismic indicators that locate potential hydrocarbon bearing reservoirs in the subsurface. Geoscientists have always been on a quest to develop new seismic attributes that can point to hydrocarbon presence...
