First task

Challenge: Find three sedimentary basins in the area. Basins are sedimentary rocks in the deep subsurface where oil and gas has been generated.

Procedure: Buy and study magnetic and gravimetric surveys; and to submit the coordinates, column and row number for each basin centre.

Gravimetric surveys

Gravimetric surveys show the gravity in the sub-surface. Measured by airborne sensors.

Sedimentary rocks have lower densities than the surrounding crystalline rocks. Low gravitational pull means high probability of a basin below.

Basins have a lower gravitational pull. Crystalline rocks have higher

gravitational pull

Gravimetric surveys

Gravimetric survey:South-east quadrant

Magnetic surveys Magnetic surveys show similar

information as gravimetric surveys. The sedimentary rocks in the basins have a lower concentration of magnetic materials than the surrounding crystalline rocks.

Sedimentary basins are the areas with the lowest magnetic field.

Basins have low magnetic field Non-basins have high magnetic

fields.

Centre Midpoint calculation

3 centres – one Centre midpoint for each basin

Example: C55, R105 Solve before deadline. All

submissions are evaluated after the deadline (and not before).

You may get 0-100 CPs. All three centres must be located to get full CPs.

Task 1 solved

All teams have submitted their answers. Basin centres are located.

Message in Inbox. All teams have answers and CPs awarded.

Task 2 license round Sedimentary basins

may contain oil and gas The government has

decided to put the blocks around one of the basins on offer

Challenge: Identify the 3 most promising blocks and submit a bid to the Government for these licences

Source and migration

1. SOURCE ROCKwhere organic material is put under sufficient pressure

2. MIGRATION ROCKwhere hydrocarbons are driven through

3. CAP ROCKImpermeable rock that stops migration of hydrocarbons 4.

PROSPECT

Geological “pockets”, that might contain hydrocarbons.

CRS. Common Risk Segment surveys tell you about the probability of a structure in the block/cell containing oil or gas

2D Seismic surveys

Traps can be found with seismic surveys

2D seismic survey is a cross section of the geological layers along either a column or a row

2D seismic surveys are used for locating prospects

ones have the most (big) structures Check water depth, and go for

shallow water blocks if possible Remember to submit 3 bids

Task 2 solved Message sent to

all teams with the results

Credibility Points are given for prosperity of the blocks you bid for

Every team has got one exploration license

Task 3 Exploration Drilling

HQ is happy with the license awarded.

Challenge: Farm-out minimum 20% from your license – and farm-in as much as you can in other good licenses.

Acquire 3D Seismic interpretations for the block you operate, and study the results from the licensing round

Get others to invest 20% or more in your license – you can show/send 3D seismic

Partnerships

Spread the risk: e.g Investing in other blocks divides the risks amongst all partners, much more preferable than keeping 100% of one field and all the risk.

Increase probability of profit: investment in only 1 field which could be a dry prospect is possible, whereas the likelihood of investing in 5 fields which are all dry is unlikely.

Overview: On the main page, you can see all licenses. 1) licenses you operate, 2) licenses you have invested in, and

other licenses.

All your farm-in offers to other teams are shown under “Investing” on the right-hand side of the homepage . This is where a team offers investments to other teams for a % of their blocks

Partners pay a proportional share of all future costs

Partners receive a proportional share of the net proceeds from oil and gas

The operator team makes all decisions regarding drilling

Teams can farm-out up to 70% of licence

Operators must keep 30% of licence

Water depth

• Before choosing a rig, you need to check your water depth

Find this at the bottom of the BLOCK page

Choose Rig Choose the right rigs for your water

depths Jack-up rigs for shallow waters

Semi-submersible rigs for middle waters

Drillships for the deepest waters

Rig cost = drilling days * day rate

Service ProvidersUpto 9 Star

quality- Good:

normally costs more

Bad: cheaper, but reliability

is low, so you risk extra drilling time and extra costs

Environmental Impact Assessment

EIA survey: more knowledge about the area.

Less probability for drilling problems. Less severe consequences if you run

into problems.

= Which drilling locations to avoid.

Drill Position EIA:

enviromental impact analysis shows where it will cost you more to drill.

reprocess seismic Decide which discoveries to drill how

many appraisal wells into

Ultimately, you should either: Get a positive net present value, Or a conclusion that additional

appraisal wells will not result in a net present value
