SKILLS and ACCOMPLISHMENTS

Include:

  • Designed and developed core calibrated petrophysical models of self-sourcing reservoirs including the
 Niobrara Formation in the DJ Basin with emphasis on porosity types, thermal maturity, and depositional
 environments.


  • Designed and prepared petrophysical models for highly laminated and low resistivity pay reservoirs.


  • Expertise in the analysis of open and cased hole logs for fluid discrimination and saturation with applications in reservoir modeling, 4D seismic characterization, Sorg/Sorw determination, assessing
 EOR performance and well intervention opportunities.
  • Developed flow capacity based petrophysical models for optimizing completion design that resulted in significant cost reductions and improved production performance.
  • Performed daily production/injection monitoring and optimization, reservoir surveillance, and designed well intervention and logging program.


  • Developed cycle well modeling and optimization program for high GOR wells.


  • Designed and coordinated logging and analysis programs for horizontal, high angle, multi-lateral, coil tubing drilled, and through-tubing rotary drilled development wells utilizing new tool technology and deployment techniques.


  • Designed and coordinated coring and analysis programs including routine and special core analysis,
 resource play crushed rock analysis, mineralogical/elemental analysis, and thin section, SEM and nano-scale imaging.
