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).
