  1. Evaluation of the Sirri Prospect Area Engineering Staff: Hamed Kamel PEEG Fahd Al-Hashmi PGEG Khaled Aness PGEG Ahmed Al-Belooshi PEEG

  2. Outline • Project Objectives • Field Background • Field Seismic Interpretation • Field Exploration Plan • Field Development Plan • Economic Analysis • HSE Awareness • Recommendations

  3. Objectives • Client’s Letter • Seismic interpretation, exploration and development plans and economic analysis • Give recommendation on whether to proceed with the project or not

  4. Field Background

  5. (2) – Long 54 38 57.2E and Lat 25 59 27.0N (4) – Long 54 45 50.7E and Lat 25 54 35.0N (1) – Long 54 33 11.0E and Lat 25 39 54.2N (3) – Long 54 26 18.0E and Lat 25 44 45.6N Geographical reference

  6. Seismic Interpretation • Rationale • Methodology • Manual Interpretation • Software Interpretation • Results

  7. N Seismic Manual Interpretation • Contouring maps • Structure analysis • Spill point determination • Finding the depth (velocity * time ) • Results: • Structure: Anticline • OOIP= 7.90 billion bbl. Spill Point

  8. Computer Interpretation • Picking horizons • Miss tied correction • Create TWTT contour map • Depth map • Find Area, volume and reservoir thickness

  9. Top Mishrif Bottom Mishrif Computer Interpretation • Picking horizons

  10. Computer interpretation • Miss-tie correction Before After

  11. Top contour map N N Bottom contour map Computer Interpretation • Create TWTT contour map

  12. N Computer interpretation • Creating Depth maps • Depth (m) = Velocity(m/s) * Time (s) Depth map of the top reservoir

  13. Spill point N Thickness map showing oil water contact Computer interpretation • Constructing a Thickness Map • Thickness= (Bottom of reservoir- Top of reservoir/2)*3800 m/s • Spill point

  14. Seismic Interpretation Results • Anticline structure • Area: 93km2 • Average thickness: 24.6 m • OOIP=Porosity*(1-Sw)*volume = 2.5 Billion bbl

  15. Exploration and Development Plan • Methodology • Location of Exploration wells • Rig selection • Scenarios Demonstration • Production Forecast • Production Facility Options • Economic Indicators

  16. Field Exploration Plan • Location of Wildcat Well: • One well at the center of the potential reservoir • Purpose • Location of Delineation Wells: • Four delineation wells at the borders • Purpose

  17. N Field Exploration Plan Wildcat well Delineation wells

  18. Field Exploration Plan • Rig selection • Jack up IS 300' WD • Reasons • Water depth 300’ • Low Cost  $82,333 per day • More working rigs

  19. Field Development Plan • Types of wells: • 500 m Vertical, 1000m Horizontal and 2000m Horizontal • Different drainage area and different cost for each type • Methodology: • At the center of the reservoir

  20. Well Profiles • Production Profiles

  21. Field Development Plan • Production Profile

  22. Field Development Plan • Production Profile

  25. Field Development Plan

  26. Scenario selection

  27. Scenario selection

  28. Comparison summary • Scenario 1: • More wells (55) • ∑ Oil production (1.3 billions bbl) • Scenario 2 : • Less wells (48) • ∑ Oil production (1.7 billions bbl)

  29. Field Development Plan • Data Set

  30. Production facilities • Three different production facilities were applied to each scenario: • FPSO only (Floating Production, Storage and Offloading unit) • Platform only • FPSO & Platform • Select based on the Economic Analysis

  31. Production Facilities • Platform • Construction (2 years) • Cost: $350million • Facilities • Gas – Oil separation facility • Water treatment facility • Pipeline • Fluid separation, processing & treatment • Gas processing • Oil treatment • Water treatment

  32. Production Facilities • FPSO • Oil production cost • 190,000 $/day + Variable rate $14/bbl

  33. CAPEX

  34. OPEX

  35. Production Facilities Options

  36. Production Facilities Options

  37. Production Facilities Options

  38. Selected Facility

  39. Economic Analysis

  40. Economic Analysis

  41. Economic Indicators

  42. HSE Awareness • Seismic survey: • Air guns effect on marine life • Exploration: • Reef life destruction & hydrocarbon leakage • Development: • CO2 emission

  43. Conclusion & Recommendation • Conclusion: • Jack up used for drilling • Both (FPSO+Platform) • Scenario 2 • Recommendation: • Start drilling exploration well • If hydrocarbons found, we recommend PI ENTERPRISES to start drilling using the 2nd scenario • If not, do not proceed with drilling
