This document provides an overview of OilSim, a simulation for the oil and gas upstream value chain. It describes the learning objectives, challenges, and tasks involved in exploring for and developing oil and gas resources. The tasks include identifying sedimentary basins from surveys, bidding on exploration licenses, acquiring seismic data, drilling exploration and appraisal wells to evaluate discoveries, and developing field production plans to maximize resource recovery. The goal is to make economically viable decisions that consider costs, risks, environmental factors, and partnerships with other teams.

Editor's Notes
- #5 Hydrocarbons – surveys to help find them Licensing roundsFarm-in and PartnershipsDrilling rigs and Sub-contractorsWell planning – transportation capacitiesFacilities – Platforms, flowlines and pipelinesConstruction – activities and timelineOperations – Issues, maintenance and OPEX
- #8 The long and bumpy road for oil from the underground to your tank, is called the oil and gas industry value chain.The value chain is divided further into these parts:Upstream is about getting the hydrocarbons up from the ground, and comprises of activities related to exploration, field development, construction, production and abandonment. By its nature, the exploration phase is common for both oil and gas, but soon afterwards, the oil and gas value chain will segregate into two parallel value chains.Midstream is about transportation and storage, as well as oil refining and gas processing.Downstream is about distribution and retail sales of gas, fuels and lubricants, plastics and other hydrocarbon derivatives to industrial and consumer markets.OilSim Exploration is all about the exploration part of the oil and gas industry. Exploration is about finding the hydrocarbons and proving that they are in sufficient quantities to start producing. OilSim Production is about actually taking the oil or gas out of the subsurface.
- #27 Since the CRS show the probabilities of prospects in only one particular horizon or layer, it is necessary to purchase the CRS for all 3 layers so that you can determine which area within the licensing area contains the highest probability of containing oil and gas. So on the CRS maps shown here the area circled in black on the OilSim map and each of the CRS shows that the area in question is within the licensing area and is green on all three CRS layers, indicating high probability of oil and gas on all 3 layers within the same area or blocks. Potentially an area that requires further investigation for individual prospects.
- #31 Hear the area between the reservoir and the sealant rock has been shaded in to show you whether you still have a seal at the fault or a gap where leakage could occur.
- #44 When reviewing a farm-out offer you can either accept the amount or % the license owner requests, or amend the amounts to your own offer. Add a message to the seller explaining why they should choose your team and press “Send offer”
- #45 Financing – Is where a team is able to accept offers, and therefore receive money or “finance” for a % of their own blocks When a team receives a Farm-In offer it appears under financing on the right hand side of the homepage
- #47 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 blocksRemember you must have farmed-out 20% of your own block before you can drill.
- #49 Before you begin to drill you need to know the water depth so that you choose the right type of rig. You can find this information by clicking on your block and scrolling to the bottom of the screen where a map of the whole block’s water depths are shown. By scrolling over each cell you can see the water depth for each particular cell.
- #50 The next task is to choose which rig to use to drill the exploration well, but you will need to know how deep the water is in the area you wish to drill, so check out the water depths under your block information.There are three types of rigs: jack-up rigs for shallow waters, semi-submersible rigs for middle waters and drillships for the deepest waters. The rigs have different costs per day, and the drilling days depend on how deep you drill into the subsurface and which service providers you chooseFew: 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.
- #52 Before you choose where to drill you should buy an Environmental Impact Assessment (EIA) survey to get more knowledge about the area. The benefit of an EIA survey is that you will be prepared for any environmental challenges you might encounter when drilling. With an EIA survey you will have lesser probability for drilling problems, and the extra costs will be less. Also, in the EIA survey you can see which drilling locations you should avoid. Some areas in your block are challenging to drill in. This can be because of strong currents, adverse conditions on the seabed or other local conditions. When you drill in those locations your costs go up 20%. You can see these locations in the EIA survey. You only have to buy one EIA survey for each license that you operate. You can find the EIA surveys under Surveys.
- #54 As this figure illustrates, you can drill through all three horizons in one well.You can even drill a deviated well, so that the position is not exactly the same in all horizons.The deviation can be 1 cell for each horizon.
- #55 To determine how long it will probably take to complete drilling, check out the “drilling Information” tab.
- #56 Inputting estimated cost of drilling gives you credibility points. You need to add all the costs of the rig and the service providers together and multiply this by the number of days you think it will take you to drill. The oil spill control is voluntary but costs 5% of the drilling amount per day but will earn you more knowledge points and cost you less to clear an oil spill if it happens.The oil spill control acts as a gas blow-out preventer too.
- #59 Cost $100000
- #63 When you have drilled the first well, you only have a small sample of the new-found oil or gas field. This is evident by the wide ranges of the area, thickness, quality, and volume variables. These wide ranges tell you that you actually do not know much about the field.After drilling and testing, your next step therefore is to drill another well – and test it. This is called an appraisal well.Normally it takes at least three or four wells into a field before the license block becomes economically viable.Sometimes it takes much more, and therefore you should not give up if the first wells into a field do not give any license value.However, you should give up if the upper boundaries of the field become so low that there is no chance that it becomes economically viable. This is often the case in deep-water blocks, where the CAPEX are very high.
- #71 Maximum amount of multiphase fluid in one year
- #75 Submit a plan for each reservoir.
- #76 Adding more wells to the reservoir will decrease the average flow rate per wellBecause any additional well will be in a less favourable location than the previous oneshave a drainage area that overlaps with a previous wellIn OilSim, the reduction is 2% for each additional well
- #79 Your task is to maximize the value compared to the money you receive from the parent company This measurement is also known as ROI, or Return On Investment.Reservoirs are so close so we treat them as one big field. You are a field development team in charge of a license blockYou have been asked to plan the facilities to produce the oil and gas that has been found in the blockYou have a number of surveys to guide youin OilSim relate to both the flowlines which transports the fluids to the seabed and the risers which then transport it to the Platform.
- #80 Metocean surveys- Can be bought under the Survey tab.For each survey there is a legend showing the probability of the environmental hazard occurring in a particular block. On the Earthquake survey, a turquoise blue indicates 1- a low probability and a reddish brown colour indicates 10 – a high probability of one occurring.So if you own block 606 – you can see on the Earthquake map that the likelihood of earthquakes is MEDIUM risk.You need to look at each survey and determine the risks of each type of hazard for your block. So that you can then select a platform that can cope with these hazards.
- #82 For exampleCompare the applied discount factors in these scenarios. If you think that your projected cashflow is spot on with a project you could have a discount factor of 0% with an expected value of licence of 189M in total over 35 year periodIf you thought there were some unknown factors that you had to consider, applying a discount factor annually of 5% to the expected production would lead to a reduced value of 118M.And if you felt that there was still a large number of unknowns to be considered, then the compounding of the annual discount factor of 20% each year, would greatly reduce the value of the licence to 48M.
- #83 Next, find the average water depth of your block by clicking on the Reservoir tab,Clicking the magnifying glass for the reservoir Then under the reservoir information the Block water depth is shown. Again, you need to know this to determine which platform would be suitable within your block.
- #84 Need to consider what capacities your platform, flowlines and pipelines are going to deal with, so you will need to determine the maximum amount of oil (or condensate), gas and water that could be produced. Examine the detailed production profileOil, Gas, Condensate, WaterLooking for maximum amount of production per dayIn an oil field- you will have Oil, gas and waterIn a gas field-you will have gas, condensate and water
- #85 Click on Facilities TabChoose your platformScroll down to Settings-update platform requirements for your reservoirAmend number and size of flowlineSelect both a pipeline for the Oil storage tanks and Gas Processing PlantUpdate diameters for each pipelineEnter number of platforms required – this number might be more than 1- if the maximum capacities are lower than that needed to transport your oil or gas.
- #86 Estimated rate – bbl/dFlowline (acts as the flowline and riser size for the total multiphase fluid (all oil/gas/condensate and water).So you need to add the maximum amounts to be produced together to work out which flowline to use. Water – either goes out to sea after cleaning or used for injection into the well.In our scenario, we have a subsea template that collects all multiphase to travel to production facility. Then the pipelines are used for the oil, condensate and gas, so you need to consider the oil types and gas separately to work out which size should be used to take oil and condensate to the storage tanks and the gas to the Flowline: Metal pipe that connects the top of the wellbore to the mud surface-treating equipment that connects the wellhead to a manifold or to production facilities, such as heater-treaters and separators.Riser: A pipe that extends from the drilling platform down to the seafloor. Drilling mud and cuttings from the borehole are returned to the surface through the riser.
- #87 Choose whether you need oil terminal and gas storage Might be more than one available to choose from, so check out costs and distance to the facilities.
- #89 Red dots indicate that the fluids cannot flow through flowlines and pipelines which current planYellow dots indicate that there is flow but that there are some constraints in the existing planGreen dots indicate that the current plan will allow the fluid to flow freely – might not be optimal plan though
- #92 This chart shows the activities, tasks, processes that need to occur in order to reach first oil.Starting at the bottom of the chart, a number of activities need to take place before you can move onto the next activity.For those activities with a dotted line attaching them to another activity – you have a choice-choose one out of the 3 optional activities available.Where there is a full straight line, then the activity has to be completed before moving on to the next step/activity.Scrolling over a possible activity will show you the estimated time it takes to complete a task, the capital and operational expenses in completing each task.
- #93 Once you have chosen the activity you need to complete, you have to decide on which provider, taking into account the CAPEX and OPEX involved as this will affect your value. Also, consider the timeframe, bearing in mind, you are trying to reach First Oil within 21 periods of 90 days i.e.. 1890 days.Consider time v. costConsider the inclusion of local contentResource analysis and try and reach First oil or gas within 5 years (20 quarters)
- #94 After reviewing the activity hierarchy and the possible resources. Submit a financial summary of your construction plan with:The anticipated capexThe expected amount of contentWhich period you think you will reach first oilAnd press submit/updateUse your printed materials to help you plan the project
- #95 For each period select a provider for each step that it is possible to complete in one period, bearing in mind that some activities cannot start until others are completed.Only pick those that can be started in this period.
- #97 After each period passes, there is an activity update under the Construction tab
- #99 On the right-hand side you can see the timeline for the project and whether you are on track for reaching First Oil before the end of the 21 periods.Each period of time is 90days and after each period of time there is an update to your activities to advise what has been accomplished, remains outstanding
- #101 At the end of all the 10 periods you will be advised if you have succeeded in achieving first oil and whether or not your company has attracted performance bonuses for your target CAPEX, local content amount and finishing on time.
- #102 We will give an Activity Hierarchy survey to teams that have purchased the survey
- #104 In this task you are producing your oil and gas and have to consider 3 scenarios that will affect your company’s strategy during the lifetime of your asset.
- #105 In each of these scenarios during the lifetime of your asset, you need to consider your company’s strategy and the market conditions presented in each scenario and decide which option would optimise your sales value.
