1. OilSim Faroes 2007 Facilitator Course Tórshavn, 2. Oktober, 2007

2. Overview Enhance your overall understanding of petroleum exploration Common platform to work on Multidisciplinary challenge You are an exploration team in charge of a new petroleum province Your task is to get maximum return on investment (ROI)

3. Money You start with $200Millions –You can apply for more money later Earnings: –Net value of the oil fields discovered –MINUS costs (surveys, wells, etc.) Winning team: –highest return on investment (ROI) –ROI = Earnings / Funds received Government Bonus for the 10 best teams

4. Learning Points Where and how to find oil Surveys used in exploration Licensing rounds Farm-in and Partnerships Rigs and Sub-contractors Reducing uncertainty Economically viable volumes

5. Oil & Gas Industry Upstream –Exploration –Development –Production Downstream –Refining –Distribution

10. Main screen

11. First task Find the 3 basins in the area Basin: Sedimentary rocks in the deep subsurface where oil and gas was generated Procedure 1.Buy and study magnetic and gravimetric surveys 2.Submit 3 block numbers; one for each basin centre

12. Surveys

13. Gravimetric surveys Gravimetric surveys show the gravity in the sub-surface Sedimentary rocks (“basins”) have lower densities than the surrounding crystalline rocks Low gravity (green) -> Basins High gravity (red) -> Crystalline rocks

14. Gravimetric surveys

15. Magnetic surveys

16. More detail North East

17. Quarter map survey

18. Enter decision

19. Task 1 Possible to get between 0 and 100 knowledge points (KP) –KP’s can be used e.g. when you apply for money Must be solved before deadline After the deadline, all submissions are evaluated

20. Task 1 solved All basins are located Message sent to all teams with the results Oil and gas is close to the basins Next step: First licensing round –The blocks around one of the basins are on offer

21. Second task Bid to get a exploration licence Exploration licence: A permission from the Government to explore a block Procedure 1.Buy and study Common Risk Segment Maps and 2D Seismic surveys 2.Submit 3 bids –Block number –Amount offered to Government (“bonus”)

22. Migration Basin Prospect Play Migration

23. Prospect Migration Reservoir Seal

24. Common Risk Segment Prospect probability –Red: low –Orange: medium –Green: high There is one CRS for each geological layer

25. Common Risk Segment Band 3 Eocene Band 2 Paleocene Band 1 Creataceous

26. Real Seismic

27. 2D Seismic surveys A 2D Seismic survey is a cross section of the geological layers –along either a column or a row Is used for locating prospects Look out for traps Three separate geological layers

28. 2D Seismic example

29. Prospects Top of sealing rock Top of reservoir rock

30. Cross-sections Column Row Prospect, Reservoir Basin, Source

31. Wells 179

32. Remarks In OilSim, there is only one type of trap: the four-way closure structural trap –in reality, there are several other types Three prospecting systems –3. Eocene (1.500 m below seabed) –2. Paleocene (2.500 m -) –1. Cretaceous (3.500 m -)

33. Tips Use CRS to see which blocks to study Buy and study many 2D surveys Focus on shallow water blocks –It is cheaper to drill exploration wells in shallow water –It is more economically viable to produce oil and gas in shallow water

34. Enter bid

35. Remarks Minimum bonus: 1000000 Maximum bonus: 30000000 You will only get one licence Highest bid gets the licence If you lose on all three blocks, you will get a random licence (of the ones that are left) Do submit 3 bids -> more KP’s and higher probability for success

36. Task 2 Submit your bid before the deadline After the deadline, all bids are evaluated, and each team gets one and only one licence

37. Task 2 solved Every team has got one exploration licence Message sent to all teams with the results Knowledge Points: a measure of how prosperous the blocks the team bid for were Next step: Farm-in

38. Farm-in & -out The headquarters of you company has evaluated the licence that you got awarded Although the possibility of finding oil is fair, the costs involved are large, and the headquarters wants you to spread the risk. This is accomplished by: –investing in other licences (farm-in), and –letting other invest in your licence (farm-out)

39. Task 3.1 Farm-out Get other’s to invest 20% or more in your licence (“farm-out”) You can only send farm-in offers (!) –Offers to buy parts of other licences Procedure for farming in: 1.Study 2D Seismic surveys 2.Submit one offer for each viable licence –Amount offered –Share wanted (in whole %)

40. Farm-in

41. Send an offer

42. Partnerships Partners pay their share of all future costs incurred by the partnership. Partners receive their share of the net proceedings from any oil found on the licence The operator team takes all decisions regarding acquirement of 3D seismic, drilling of wells and testing of wells

43. Task 3.1 Study 2D seismic surveys of the other licences Submit your bids –Minimum amount 100,000 for 1% You are not allowed to drill before at least 20% of your licence has been farmed out You can farm-in & -out at any time Partners in a block get all info about drilled wells and discovered prospects

44. Task 3.1 Partnerships will be established every time a seller accepts an offer On the main page, you can see all the licences –The licences you operate –The licences you have invested in –Other licences Next task: order rig

45. Task 3.2 Rig 3 rig types –Drillships –Semi-submersibles –Jack-up rigs Different water depths, Different day rates –Rig cost = drilling days * day rate

46. Available Rigs

47. Drilling days

48. Drilling Depths Seabed 3500 m below seabed Layer 3 Eocene Layer 2 Paleocene Layer 1 Cretaceous 1500 m below seabed 2500 m below seabed “water depth”

49. Seabed Depth

50. Task 3.2 Rigs

51. Rigs Limited number of rigs available You can order a rig –use it within 20 minutes Not enough for all –Wait in a queue, if another team is using the rig Rig day rates are dynamic

52. Task 3.3 Providers

53. Track Record

54. Select Providers

55. Task 3.4 Position You have to choose where to drill –Which cells?..and how deep to drill –Either to the Eocene horizon –Through the Eocene to the Paleocene horizon, –or through the Eocene, the Paleocene, and to the Cretaceous horizon

56. 3D Seismic Shows the structure: –in one (of the three) horizons –in one block Look out for “tops” –a top = a trap = a prospect

57. 3D Seismic

58. Three targets Layer 1 Creataceous Layer 2 Paleocene Layer 3 Eocene Column 60, Row 79 Column 60, Row 78

59. Select Positions

62. Drilling position 2

63. Conf. & Budget

64. Drilling results

65. Drilling result

66. Task 3.5 Testing If you discover a field-> decide whether you want more information about that field You get more information by doing a production test (and other tests) Tests take 10 days per field Tests have the same day-rate as the drilling (you use the same providers)

67. Test decision

68. Field value

69. Prospects

70. Licence Value

71. Appraisal

72. –From Probable volume to proven reserves

73. Narrowing ranges First well: –0 to 572 MBO (after drilling) –11 to 266 MBO (after testing) –Proven volume: 11 MBO Second well –11 to 233 MBO (after drilling) –35 to 210 MBO –Proven volume: 35 MBO

74. Continue... Drill appraisal wells to narrow the uncertainty (get proven volumes) Drill into other prospects Farm-in and -out Two additional licensing rounds Apply for more money, if you run out of cash Winner: highest ROI
