Next Step
• Choose a workable field– Big Tensleep field with thick ROZ.– Collaborated with the operator.– HC show records and oil analysis.
• Determine oil saturation, petrophysics, and crude quality– Core measurements.– Log analysis.– Deepen and core through ROZ.– Production test in ROZ.– Obtain oil/fluid samples.
• Calculate CO2 flooding potential for both ROZ and MPZ• Propose CO2 flooding designs
– Pilot operations.– WAG, CO2 only, or gravity stable.
