Research interests: Alejandro is interested in several aspects of exploration and earthquake seismology. He uses mathematical and physical tools to better understand processes that occur in the subsurface from data recorded at the surface, a.k.a. the typical geophysical inverse problem. Below he describes the two avenues of research that he has been recently exploring.

1.Super resolution (current work): For a long time it has been thought that beating the diffraction limit is an impossible task to perform. Recently, it has been experimentally shown that in complex media super-resolution may be achieved as the medium heterogeneity increases the angles from which the subsurface is illuminated. I’m interested in knowing: what receiver geometries increase image resolution, how the resolution depends on the velocity model, and how the seismic resolution changes for a given experimental set-up.

2. Coda waves (previous work): Coda waves are composed of seismic waves that have scattered multiple times in their path from the source that originated them to the receiver where they are recorded. They contain meaningful information about the subsurface in the form of seismic scattering and intrinsic absorption. These two properties, however, are hard to separate from one another. I’m interested in methods which allow separating these two properties and that agree with geophysical/geological observations.

Research interests: Tjaart joined Mines from the Applied Geophysics group at the Institute of Mine Seismology. His primary research focus is on the further development of time-lapse monitoring of velocity variations using seismic interferometry in various industrial applications, most notably tailings storage facilities. Tjaart is also involved in further research in industrial applications of seismic interferometry, for example, surface wave tomography for passive seismic exploration.

Patipan Saengduean CV

Advisor: Roel Snieder

Patipan’s research interests are microseismisity and seismic interferometry. He is currently working on the applications of the virtual seismic method (VSM) to obtain wave responses (Green’s function) and to hopefully obtain geo-mechanical properties within different source scenarios (e.g., subduction earthquakes and micro-earthquakes induced by fluid injections).

Sagar Singh
PhD student

Biography
sagarsingh@mines.edu
Sagar Singh CV

Advisor: Ilya Tsvankin

Sagar is currently working on Full Waveform Inversion(FWI) for Reservoir Characterization with the idea to constraint FWI work-flow using rock physics relationship with elastic properties to provide very high resolution image in depth domain. He is currently working with Elastic VTI model and will extend it to an elastic orthorhomic model in future. He also intends to do targeted reservoir parameter inversion using local solvers in time domain.

Cullen Young
PhD student

cullenyoung@mymail.mines.edu

Advisor: Jeffrey Shragge

Cullen collaborates with USGS and CWP in his research. The goal is to examine a large-scale DAS VSP dataset from the Alaska North Slope with the aim of better understanding the time-lapse rock physics and seismic properties of hydrate production. To do this we are utilizing synthetic acoustic and elastic RTM as well as least-squares RTM to image and estimate subsurface properties. Finally, these techniques will be applied to the DAS VSP field data to constrain the baseline subsurface properties.
