2-D Velocity structure of Kerala-Konkan region using seismic traveltime Inversion
Existence of gas-hydrates in the marine sediments elevates the velocity of seismic waves, whereas even a small amount of underlying free-gas decreases the seismic velocity considerably. These changes in velocities can be used for the assessment of gas-hydrates. The traveltime inversion is an effective method to derive a 2-D velocity structure from the seismic data. We have applied the method to...

متن کاملcrustal seismic velocity structure study in kope dagh using simultaneous inversion modeling
crustal velocity structure model has a significant role in truly understanding of seismicity and also in relocating earthquakes. on the other hand, it can be used for recognizing major and potential seismic sources which is very critical for seismicity and earthquake hazard assessment studies. seismic parameters simultaneous inversion modeling is one of the most prevalent methods in the study o...
متن کاملPre-stack Simultaneous Inversion of 3D Seismic Data for Velocity Attributes to Delineate Channel Sand Reservoir
Channel sand acts as stratigraphic trap for hydrocarbon accumulation in many parts of the world. Delineation of this type of reservoir is crucial as channel sand may be scarce and inaccurate location of the drilling wells could lose a huge currency. To differentiate channel sand from the host rocks, attributes such as P and S wave velocity ratio plays a vital role in the study area. The velocit...
متن کاملInversion of seismic attributes for velocity and attenuation structure
We have developed an inversion formulation for velocity and attenuation structure using seismic attributes, including envelope amplitude, instantaneous frequency and arrival times of selected seismic phases. We refer to this approach as AFT inversion for amplitude, (instantaneous) frequency and time. Complex trace analysis is used to extract the different seismic attributes. The instantaneous f...
