      • 2017 - Jan 2021

      Primary area of focus was the Pinedale Field. • Led the Lance Pool reservoir characterization efforts for the vertical well program; identified the key variables governing gas productivity and prioritized the vertical well inventory • Spearheaded the Lance Pool reservoir characterization initiatives for the horizontal program; utilized new generation NMR to find the fingerprint of super-productive zones (HZ target); and creatively interpretated open-hole logs in laterals to find the boundary of the gas charged sands •Developed a Dielectric-log-calibrated petrophysics saturation model Show less
