Internship, Research & Work Experience
-
2013 Internship at Schlumberger, Houston. (May 2013 - Aug 2013
Project: Enhancing Geological Interpretation by a New Technology - eXchroma
- Facilitated the commercialization of eXchroma in Petrel.
- Invented a new method potentially integrated in eXchroma future versions.
- Extracted 3D turbidite body by eXchroma, multi-client wide-azimuth seismic, Gulf of Mexico.
- Conducted drilling hazards visualization and channel body extraction, offshore West Africa.
- Evaluated and tested eXchroma for high-resolution characterization of seafloor and top salt.
- Investigated on how to utilize eXchroma to upgrade geological interpretation.
- Created technical documentation of eXchroma for Petrel and for training users and clients.
-
2011 Full-time internship at Shell Oil Company, Houston. (May 2011 - Aug 2011)
Project: Fracture Detection & Visualization for Onshore Unconventional Oil/gas Reservoirs
- Visualized and quantified the fractures of unconventional reservoir formations (e.g. Haynesville & Bossier) in the Magnolia & Cuervo regions(US continental) by using seismic images in different azimuths.
- Utilized a modern fracture detection tool, multi-azimuth co-rendering, to visualize fractures.
- Digitized the seismic data of three azimuths and co-rendered them into one image
- Identified 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.
- Acquired detailed geological information for the unconventional reservoirs.
- Recommended research team to improve the Shell interpretation software (GeoSigns/nDI).
- QC the seismic data and created a workflow handbook for the company.
- PhD Project: Reservoir Characterization on Fine Scales by Seismic Waveform Inversion using Particle Swarm Optimization (PSO)
- Invented a new version of PSO optimizer
- Examined PSO in reservoir petrophysics to quantify properties of reservoir rocks and fluids.
- Investigate PSO in seismic waveform inversion to visualize & quantify reservoir rock & fluid properties and their variations during oil production by 4D time-lapse seismic inversion.
- Workflow: seismic dataàseismic inversion(PSO)àseismic-related propertiesàrock physics & well logsàreservoir rocks' & fluids' properties (e.g. porosity, fluid saturation, lithology, etc).
