Research Experience

• 2013 Summer Full-time Internship at Schlumberger (May~Aug, 2013)
• PhD Project on Reservoir Petrophysics & 4D Seismic Inversion [2010~present]
• Supported by Department of Energy (DOE).
• Research on a new optimizer in oil industry-- Particle Swarm Optimization (PSO)
• Apply PSO in reservoir petrophysics to quantify the properties of reservoir rocks and fluids.
• Apply PSO in 4D time-lapse seismic inversion to quantify & visualize the changes of reservoir rock & fluid properties during oil production.
• Workflow: seismic data à seismic inversion (PSO) à seismic-related properties à rock physics & well logs à reservoir rocks' & fluids' properties (e.g. porosity, fluid saturation, lithology, etc.).
• Full-time Internship at “Shell Exploration & Production Co.” (Houston) [May~Aug/2011]
• Project: Seismic Azimuthal Visualization and Diagnostics for onshore unconventional oil/gas.
• Visualize and quantify fractures of unconventional reservoir formations (e.g. Haynesville & Bossier) in the Magnolia & Cuervo regions(US continental) by using seismic images in different azimuths.
• Develop a new optimal fracture detection tool --RGB co-rendering-- to visualize fractures.
• Digitize the seismic data of three azimuths by red, green and blue colors respectively.
• Identify the areas with favorable fracture densities and orientations to optimize horizontal drilling plans and improve drilling success ratios in the fracture-dependent unconventional reservoirs by using azimuthally varying p-wave attributes.
• Communicate with Geologists and Geophysicists and help them acquire detailed geological information for those reservoirs.
• Feedback to the research team to improve the Shell interpretation software (GeoSigns/nDI).
• QC the seismic data and write a workflow handbook for the company.
• ExxonMobil course--Integrated Basin Analysis [11/2011]
• Elected to participate in SEG/ExxonMobil Student Program [09/2011]
• Sedimentary Basin Field Trip in Southern Oklahoma [11/2009]
• Seismic Simulation by MPI Parallel Computation [2007~2009]
• Modeling 3-D Seismic Waves and Earthquake Dynamic Rupture Process on Complex Faults by “Curvilinear-Grid Finite Difference Method”. This work was presented in AGU, 2008.
