A key challenge in the seismic imaging of reflectors using surface reflection data is the subsurface illumination produced by a given data set and for a given complexity of the background model (of wavespeeds). The imaging is described here by the generalized Radon transform. To address the illumination challenge and enable (accurate) local parameter estimation, we develop a method for partial ...
In some cases, the variations in the subsurface rock property with time can be observed during fluid flow process because of changes in stress, pore pressure, temperature, degree of consolidation, and fluid content. Detecting these changes via their influence on the in situ elastic properties serves as the basis for timelapse monitoring. Acquisition and processing of high-fidelity time-lapse se...
With the growing demand of high-resolution subsurface characterization from 3D seismic surveying, the size of 3D seismic data has been dramatically increasing, and correspondingly, the process of interpreting seismic data is becoming more time consuming and labor intensive. Recently, there has been great interest in various supervised machine learning techniques that can help reduce the time an...
RAMACHANDRAN, SHANKAR. Stack Space Analysis for ARM Executables. (Under the direction of Dr. Alexander Dean). Bounding maximum stack depth for embedded system applications is essential in order to avoid conditions such as stack overflow. Stack usage information is useful for allocating the stack into a memory hierarchy. Prior work in stack space analysis addresses specific issues such as handli...
Seismic observations in volcanically active calderas are challenging. A new cabled observatory atop Axial Seamount on the Juan de Fuca ridge allows unprecedented real-time monitoring of a submarine caldera. Beginning on 24 April 2015, the seismic network captured an eruption that culminated in explosive acoustic signals where lava erupted on the seafloor. Extensive seismic activity preceding th...
A new and significant source of information on earthquake studies has been provided by space geodesy. The data which are gathered by various techniques of space geodesy, can quantify potential of seismic activity in the region of interest. To achieve this goal, the main advantage of extra-terrestrial geodetic data in comparison with the conventional data from geology and seismology is the abili...
Subsurface mapping of the distribution reservoir is essential to be conducted in order minimize many risks such as financial losses and also increase profit from hydrocarbon production. This research was on Jatibarang conglomerate Melandong Field, North West Java Basin, Indonesia. There are three objectives this study which perform elastic impedance (EI) seismic inversion using available 3D dat...
many steps of seismic data processing sequence suppose that data sets are sampled in time and spatial dimensions uniformly. today, this assumption is true but only in time dimension. modern seismic exploration equipment permits seismic data sets to be sampled uniformly and densely in time dimension. however, along spatial dimension uniform and dense sampling are not possible because of operatin...
