A Comparison Of Coherence Enhancement, Probabilistic Neural Network, And Convolutional Neural Network Fault Imaging With Manual Interpretation In The Taranaki Basin Area, New Zealand.
(2021-05-17)
Fault identification is a key aspect in seismic interpretation, and model generation is an essential task to achieve any accurate, precise reservoir modeling or structural framework that solves problems in the subsurface. ...
Diffraction imaging using Geometric-mean Reverse-Time Migration and Common Reflection Surface
(2017-12)
Diffracted waves contain a great deal of valuable information about small-scale subsurface structure such as faults, pinch-outs, karsts and fractures, which are tightly related to hydrocarbon accumulation and production. ...
DEVELOPMENT OF INDEPENDENT COMPONENT ANALYSIS FOR RESERVOIR GEOMORPHOLOGY AND UNSUPERVISED SEISMIC FACIES CLASSIFICATION IN THE TARANAKI BASIN, NEW ZEALAND.
(2018)
During the past two decades, the number of volumetric seismic attributes have increased to the point in which interpreters are overwhelmed and cannot analyze all the information available. Principal Component Analysis (PCA) ...
SEISMICITY AND SOURCE SPECTRA ANALYSIS IN SALTON SEA GEOTHERMAL FIELD
(2016)
The surge of “man-made” earthquakes in recent years has led to considerable concerns about the associated hazards. Improved monitoring of small earthquakes would significantly help understand such phenomena and the underlying ...
High Resolution Sequence Stratigraphy of the Leonardian Bone Spring Formation Outcrop of Bone Canyon, Guadalupe Mountains, West Texas and its Correlation to the Subsurface
(2020-05)
The purpose of this Thesis is to analyze the Upper Leonardian Bone Spring Formation, Cutoff Formation, and Early Guadalupian Brushy Canyon Formation in the outcrop of Bone Canyon located along the Western Escarpment of the ...
CONTROLS OF PRE-EXISTING NORMAL FAULTS ON THE GEOMETRY AND LOCATION OF THRUST FAULTS IN FOLD-THRUST BELTS
(2016)
Pre-existing normal faults are commonly cited as influencing both the sequence of faulting and the location of thrust faults in fold-thrust belts. Scaled experimental models for both frictional and ductile detachments were ...
Interpretational variations of seismic attribute analysis as compared within the time and depth domains
(2022)
Migration is one of the crucial data processing steps re-locating the recorded seismic events to their true locations, suppressing the diffractions and thus, providing more accurate imaging of the subsurface. It can be ...
Linking image processing and numerical modeling to identify potential geohazards
(2017-08)
Faults, along with natural fractures, may enhance production when confined within the reservoir. However, if the fault is connected to an aquifer, it may cause early water breakthrough in the reservoir. Even if they are ...
Assessment of spectral attributes in identifying gas hydrates in seismic data from the Pegasus Basin, offshore New Zealand
(2023-05-13)
Gas hydrates are formed in the subsurface along shallow ocean basins or in permafrost settings, and are commonly identified in the seismic data by the bottom-simulating reflector (BSR). Various methods have been employed ...
Aspects of Seismicity Clustering, Subsurface Structure, and Stress Orientations
(2020-05-08)
I study aspects of seismicity clustering, subsurface structures and stress orientations by analyzing seismicity at two of the most seismically active regions in the USA (Hawaii and Central USA). The notable volcanic, ...
