First taskChallenge: Find three sedimentary basins  Procedure: Buy and study magnetic and gravimetric surveys Submit the coordinates for each centreColumn and row number for each basin centre
Gravimetric surveysGravimetric surveys indicate changes in the gravitational pull of the Earth in different areas of the sub-surface.
Lower gravitational fields  indicates likelihood of low density rocks –Sedimentary rocks, porous and hopefully containing hydrocarbonsSurveys in OilsimSurvey shopGravimetric survey of North-west area
Magnetic surveysMagnetic surveys show anomalies in in the expected magnetic field of the Earth in particular areas. Sedimentary rocks in the basins have a lower concentration of magnetic materials and lower magnetic field than the surrounding crystalline rocks.
Survey in OilSimMagnetic survey:North-west quadrant
Survey in OilSimAll four quadrant surveys in map context
Finding the Midpoint
Survey analysisLocate edges of the continous basin structureLocate the diagonals and thus basin centre
Centre may not be the sameExample:Top basin on both maps Calculate the midpoint between the gravimetric and magnetic centres found= C55 and R105C50R100C60R110
Centre Midpoint calculation3 centres – one Centre midpoint for each basinExample: C55, R105Solve before deadline. All submissions are evaluated after the deadline (and not before).You may get 0-100 KPs. All three centres must be located to get full knowledge points.

Task 2 license roundThe government has decided to put the blocks in one of the basins on offer.Challenge: Identify the 3 most promising blocks and offer an amount for each of them.Licensing area

Environmentally Sensitive areasRed areasYou will not be awarded blocks that contain any red spots (spawning grounds)Blue areasBlocks in area may be awarded
Common Risk SegmentCRS. Common Risk Segment surveys tell you about the probability of a structure in the block/cell containing oil or gasSurfaceLayer 3 Eocene1500m below the seabedLayer 2 Paleocene2500m below the seabedLayer 1 Cretaceous3500m below the seabed
2D Seismic surveysTraps can be found with seismic surveys and sound waves bouncing off structures 2D seismic survey is a vertical cross section of the geological layers along either a column or a row

You will only getawarded one block – and only pay for one
Highest bid wins
If equal, then team with highest KP winsRecap on Task 2Environmentally sensitive areas – blocks to avoid Common Risk Segment surveys – areas of higher probability of prospects 2D seismic – blocks with most structures Final tip - Check water depth - shallow water blocks
Task 2 solvedMessage sent to all Results and KPsOne license per team
Task 3 Exploration DrillingThe headquarters of your company has evaluated the license that you were awarded.Although the possibility of finding oil is fair, the costs involved are large. Thus the headquarters want you to spread the risk. Challenge: You shall farm-out minimum 20% from your license – and farm-in as much as you can in other good licenses.
Task 3a PartnershipsAcquire 3D Seismic interpretations for the block you operate, and study the results from the licensing roundFarm-out: Get others to invest 20% or more in your license – you can send them surveysFarm-in: Send offers to other teams to buy shares in their viable licenses. Submit an offer for each viable license, with amount offered and share wanted in whole %.

PartnershipsSpread 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.

Farm-inlicense OWNER decides whether to ACCEPT or REJECT the offerPartnerships established every time a license owner accepts an offer.Overview: On the main page, you can see all licenses. 1) licenses you operate, 2) licenses you have invested in, and other licenses.
Farm-inAll 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
PartnershipsPartners pay a proportional share of all future costs incurred by the partnershipPartners receive a proportional share of the net proceedings from any oil or gas found on the license. The operator team makes all decisions regarding acquiring 3D seismics, drilling of wells and testing of wells. Information: partners in a block can access info about drilled wells and discovered oil and gas fields.
Water depthBefore choosing a rig, you need to check your water depth Find this at the bottom of the BLOCK page
Choose RigChoose the right rigs for your water depthsJack-up rigs for shallow watersSemi-submersible rigs for middle watersDrillships for the deepest waters Rig cost = drilling days * day rate
RigsFew: limited number of rigs available.If you get one: start using it within 20 minutes.If you don’t: wait in a queue, if another team is using the rig.Price can change: rig day rates are dynamic.
Drilling Days
Service ProvidersUpto 9 Star quality-Good: normally costs moreBad: cheaper,      but reliability is low, so you risk extra drilling time and extra costs
Environmental Impact AssessmentEIA survey: more knowledge about the area.Less probability for drilling problems.Less severe consequences if you run into problems.
Drill PositionEIA: enviromental impact analysis shows where not to drill.Place your mouse where  to drill
Penalties & FinesCertain problems can occur if Service Provider Selection is poor qualityOther penalties can occur if you drill in areas indicated as problematic in the Environmental Impact AssessmentAs in real life, problems can occur randomly and these are also applied with fines levied accordingly.
