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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
Surveys Jens Petur Bærentsen Marcos Monteferrante Simprentis
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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
Gravimetric surveys Jens Petur Bærentsen Marcos Monteferrante Simprentis

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

Wells 79 1 Jens Petur Bærentsen Marcos Monteferrante Simprentis
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 -) Jens Petur Bærentsen Marcos Monteferrante Simprentis
Common Risk Segment • Prospect probability – Red: low – Orange: medium – Green: high Jens Petur Bærentsen Marcos Monteferrante Simprentis
Tips • Use CRS to see which blocks to study • Buy and study many 2 D 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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
Enter bid Jens Petur Bærentsen Marcos Monteferrante Simprentis
Remarks • Minimum bonus: 1000000 • 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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
Task 2 • Submit your bid before the deadline • After the deadline, all bids are evaluated, and each team gets one and only one licence Jens Petur Bærentsen Marcos Monteferrante Simprentis
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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
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) Jens Petur Bærentsen Marcos Monteferrante Simprentis
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. 2. Study 2 D Seismic surveys Submit one offer for each viable licence – Amount offered – Share wanted (in whole %) Jens Petur Bærentsen Marcos Monteferrante Simprentis
Farm-in Jens Petur Bærentsen Marcos Monteferrante Simprentis
Send an offer Jens Petur Bærentsen Marcos Monteferrante Simprentis
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 3 D seismic, drilling of wells and testing of wells Jens Petur Bærentsen Marcos Monteferrante Simprentis
Task 3. 1 • Study 2 D 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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
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 Jens Petur Bærentsen Marcos Monteferrante Simprentis
Available Rigs Jens Petur Bærentsen Marcos Monteferrante Simprentis
