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.
![Page 12: Offshore ppt e&p](https://reader038.fdocuments.net/reader038/viewer/2022102813/547cc636b4af9f5b4c8b45e1/html5/thumbnails/12.jpg)
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
![Page 13: Offshore ppt e&p](https://reader038.fdocuments.net/reader038/viewer/2022102813/547cc636b4af9f5b4c8b45e1/html5/thumbnails/13.jpg)
Gravimetric surveys
Gravimetric survey:South-east quadrant
![Page 14: Offshore ppt e&p](https://reader038.fdocuments.net/reader038/viewer/2022102813/547cc636b4af9f5b4c8b45e1/html5/thumbnails/14.jpg)
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 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.

Improve value – revise well plan1. Submit plans with different number of wells
and tubing sizes1. Review Reservoir information after each
revised plan 2. Aiming to maximize sales value and
minimize drilling costs, whilst increasing Recovery Factor
3. You can amend your well plans until the deadline
4. Credibility points – upto 100 kp if plans are optimal for all your reservoirs
5. After deadline – Value of Licence will be adjusted based on final Well Plan submitted
