OilSim Exploration
  • OLF OILSIM 2008

2
Overview
  • Purpose Enhance your overall understanding of
    petroleum exploration
  • 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 200 Million
  • You can apply for more money later
  • Value
  • Net value of the oil fields discovered
  • MINUS costs (surveys, wells, etc.)
  • Winning team
  • highest return on investment (ROI)
  • ROI Earnings / Funds received

4

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

11
Surveys
12
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) -gt Basins
  • High gravity (red) -gt Crystalline rocks

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

19
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

20
Second task
  • Bid to get a exploration licence
  • Exploration licence A permission from the
    Government to explore a block
  • Procedure
  • Buy and study Common Risk Segment Maps, 2D
    Seismic surveys, and Spawning Ground Maps
  • Submit 3 bids
  • Block number
  • Amount offered to Government (bonus)

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

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 -)

30
Common Risk Segment
  • Prospect probability
  • Red low
  • Orange medium
  • Green high

There is one CRS for each geological layer
31
Common Risk Segment
Band 3 Eocene
Band 2 Paleocene
Band 1 Creataceous
32
Spawning Grounds
  • There are spawning ground areas in the map
    these are environmentally sensitive areas where
    fish breed
  • Some spawning grounds might be in the blocks that
    have been offered
  • However, no licences will be awarded in blocks
    that are spawning grounds
  • To find out which blocks are spawning grounds,
    you can buy a Spawning Ground Survey

33
Spawning Ground Survey
Red AreaSpawning Grounds You will not be
awarded blocks that contain any red area
Blue AreaNot Spawning Grounds
The survey covers the whole area
34
Tips
  • Study spawning ground maps to see which blocks to
    avoid
  • 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

35
Enter bid
36
Bidding
  • 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 -gt more KPs and higher
    probability for success

37
Task 2
  • Submit your bid before the deadline
  • After the deadline, all bids are evaluated, and
    each team gets one and only one licence

38
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

39
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)

40
Task 3.1 Farm-out
  • Get others 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
  • Study CRS and 2D Seismic surveys
  • Submit one offer for each viable licence
  • Amount offered
  • Share wanted (in whole )

41
Farm-in
42
Send an offer
43
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

44
Task 3.1
  • Study CRS and 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 oil and gas fields

45
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

46
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

Task 3.2 Rigs
52
Rigs
  • Limited number of rigs available
  • You can order a rig
  • Start using it within 20 minutes
  • Not enough for all
  • Wait in a queue, if another team is using the rig
  • Rig day rates are dynamic

53
Task 3.3 Providers
54
Track Record
55
Select Providers
56
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

57
Environmental Impact Assessment
  • Buy an EIA survey to get more knowledge about the
    area
  • EIA equals
  • Less probability for drilling problems
  • Less severe consequences if you run into problems
  • In the EIA you can also see which drilling
    locations to avoid

58
3D Seismic
  • Shows the structure
  • in one (of the three) horizons
  • in one block
  • Look out for tops
  • a top a trap a prospect

Task 3.5 Testing
  • If you discover a field-gt 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)

Appraisal
  • From Probable volume to proven reserves

74
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

75
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
