  2. Agenda Introduction 10:30 – 10:45 Petter Eltvik Welcome to Gullfaks/Bergen 10:45 – 11:00 Erik Hodneland LUNCH - Tapas 11:00 – 11:30 Gullfaks surface/subsurface landscape 11:30 – 11:50 Rune/Petter one group each. Student presentations part A 11:50 – 12:00 NTNU groups 2 & 5 present results from part A Gullfaks IOR pilot 12:00 – 12:30 Rune Instefjord Splitting students into three groups 12:30 – 14:30 Rotation 30 min in each room Rune: room V113 – H1 production history, IOR chemicals and HSE Rasim: room V108 - Reservoir simulation, Eclipse and Floviz Petter: room V104 – Gullfaks structural geology, effects on fluid flow Finalizing text for task B 14:30 – 15:30 All groups finalize text for part B. Group 1 & 6: Rune Group 2& 5: Petter Group 3 &4 Rasim Summing up/way forward 15:30 – 16:00 Students/teachers/Statoil

  3. GullfaksVillage2012 – Group 3 &4 - Rasim Huseynov IOR-challenge 1. Existing H1 model with faults and new production wells 1. Discuss geological factors that lead to the good communication Lower Brent Group of the H1 segment at Gullfaks. Make a base case simulation with the H1-model with existing wells. Additional perforations in the wells are possible. 2. The group shall make a simulation run where the transmissibility across all faults are set to zero. 3. Increase the number of wells to get an oil recovery similar to the base case. 4. Calculate the Net Present Value (NPV) of the additional wells in the case of reduced communication relative to the base case. Well cost is 200 MNOK and oil price fixed to 100 $/bbl. Use discount of 8%.

  4. GullfaksVillage 2012 Group 2 &5 – Rune Instefjord IOR-challenge 2. Existing H1 model with permeability modifications. 1. Discuss the use of the Abio gel and how it can be simulated in Eclipse. 2. Make a base case Eclipse simulation with existing wells in H1 without chemical injection. Additional perforations in the wells are possible. 3. Simulate chemical injection with use of permeability reduction keywords in Eclipse. Tips: Use tracer option to find out where the waterways are. 4. Estimate EOR and calculate Net Present Value for the measure. Chemical cost is 20 MNOK and oil price fixed to 100 $/bbl. Use discount of 8%.

  5. GullfaksVillage 2012 – Group 1 & 6 – Petter Eltvik IOR-challenge 3. Existing H1 model with transmissibility multiplicators between cells 1. Discuss the use of the Abio gel and how it can be simulated in Eclipse. 2. Make a base case Eclipse simulation with existing wells in H1 without chemical injection. Additional perforations in the wells are possible. 3. Simulate chemical injection with use of transmissibility reduction keywords in Eclipse. Tips: Use tracer option to find out where the waterways are. 4. Estimate EOR and calculate Net Present Value for the measure. Chemical cost is 20 MNOK and oil price fixed to 100 $/bbl. Use discount of 8%.

  6. GullfaksVillage2012 – Group rotation 12:45-13:15 13:15-13:45 13:45-14:15 Group 3&4: V113 -> V104 -> V108 Group 1&6: V104 -> V108 -> V113 Group 2&5: V108 -> V113 – V104

  7. Suggested economic assumptions and sensitivities • Economics assumptions • Oil price 2011 : 100 USD/bbl • Discount factor: 8 % • Run before tax economics • Value and Net Present Value • Internal Rate of Return (IRR, %) • Sensitivities • Oil and gas prices increasing 5% p. a./decreasing 3 % p. a. • Production +/- 30 % • Investments: +/- 40 %

  8. Rest of the visit.. Maxitaxi Opplæringsseteret 16:00 Pizza på Peppes Nestun 16:30 – 18:00 Maxitaxi Nesttun 18:15 På Flesland 18:50 Fly til Trondheim 19:40
