Well Test Analysis in Horizontal Wells

  1. 1. Well Test Analysis in Horizontal Wells Group: BTP-3
  2. 2. What it provides • Initial reservoir pressure (pi) • Permeability thickness (kh) • Skin (S)Menu • Wellbore perforated length (Hw) • Distance of horizontal wellbore to bottom of formation (Zw) • Permeability and effective permeability
  3. 3. Well Testing in Horizontal WellsWhere horizontal drilling is useful:• Natural vertical fractures• Thin layered reservoir• Old reservoirs that no longer have adequate drive mechanisms• Producing reservoirs with extremely high dip angles• Exploration and development of inaccessible locations• Areas where environmental concerns minimize number of surface locations
  4. 4. Problems in Horizontal Well Testing• Three dimensional flow geometry - Interpretation• Zonal variation of vertical permeability
  5. 5. Types of Pressure Transient Tests• Build-up Tests• Drawdown Test• Interference Test• Pulse Test• DST
  6. 6. The general flow patterns that areencountered in horizontal well testing: Flow Patterns Radial Linear Early Radial Early Linear Late Radial Late Linear
  7. 7. Our Project• We are investigating about permeability and skin factor.• Problems that are encountered in determining parameters and way to overcome that.

  17. 17. MethodologyMethodology to be opted for B.Techproject well testing analysis inhorizontal well• Literature survey includes – Research papers – Book collection – Chapter distribution for report writing
  18. 18. Methodology• Collection of various horizontal well data from companies:- – different well test data• For the history match and future forecasting – Well logs Work over history – Production history – Injection history
  19. 19. Methodology• Comparison of company’s calculated permeability and skin factor with our calculation done by using – PanSystem – FEKETE (decline curve analysis)• Performance prediction and history matching by using CMG software.
