Presentation Transcript

  1. Waterflood History Match + Tracer Design Goals: • History match primary and waterflood production: • Only match production after 1970 • Earlier production records not available • Adjust reservoir size and area heteregeneities • Vary Dykstra Parsons coefficients to obtain correct permeability field • Vary layering to match breakthrough times

  2. Waterflood History Match + Tracer Design Goals: • Design tracer to understand layering in detail & predict: • Minimum and maximum breakthrough times • Concentration profiles • Tracer volumes • Sampling schedule

  3. Digitized Structure and Net Sand

  4. Field History Match

  5. Individual Well Matches

  6. Water Position at Various Times

  7. Ternary Cross Sections • Time across and cross section down

  8. Tracer Movement Profiles

  9. Waterflood Tracer Design - Conclusions • Primary and recent waterflood history matched • Tracer design created • Model will be updated after tracer breakthrough to: • Optimize waterflood recovery • Minimize water production
