Simpler World Refining Page 1 In this simpler world there are only two types of crude oil and two types of refinery. Crude "A" is light and sweet. Crude "B" is heavy and sour. In Year 1 the prices of the two crudes were about equal in dollars per barrel but by Year 4 the prices of each have increased rapidly and a gap has developed between the two as shown in the tables below: Crude Prices, $/bbl Year 1 Year 2 Year 3 Year 4 Crude A 24.30 29.60 39.60 50.30 Crude B 24.10 28.20 36.30 41.60 Crude Prices, $/tonne Year 1 Year 2 Year 3 Year 4 Crude A 185 225 301 382 Crude B 173 202 260 298 Demand for refined products is growing. From Year 1 to Year 3 total demand grew by 2.8% per year (from 3.41 billion tonnes to 3.61 billion tonnes). In Year 4, however, demand growth has been constrained, especially for diesel oil, due to tight supplies. Total demand grew about 2% in Year 4, to 3.68 billion tonnes. Market experts have estimated that demand for gasoline and diesel oil would have been 5 million tonnes and 23 million tonnes higher, respectively, in Year 4 if it weren't for the tight supply situation. Gasoline prices over the period increased substantially, from 35 $/bbl to 64 $/bbl. Diesel oil prices increased even more, from 30 $/bbl to 65 $/bbl. Crude oil supplies also increased over the period, by 2.5% per year (from 3.62 billion tonnes to 3.90 billion tonnes). Refinery capacity grew somewhat slower but is still equal to crude oil supply. New refining capacity has been built in oil producing regions. In this simpler world there are two types of refinery: Type A (simple "hydroskimming" refineries) and Type AB (complex high conversion refineries). In Year 1 the operators of the Type A refineries had a gross refining margin (not including operating cost) of 13 $/tonne running Crude A. In Year 4, in spite of higher prices, these refiners saw their margin drop to 5 $/tonne. Margins running Crude B were negative both years. For the Type AB refinery operators the situation was different. Gross margins in Year 1 had been 33 $/tonne running Crude A and 57 $/tonne running Crude B. In Year 4 their margins had increased to 58 $/tonne with Crude A and 164 $/tonne with Crude B. The tables on the following page provide information about crude supply, refining capacity, demand for gasoline and diesel oils, plus yields and Simpler World Refining Page 2 production data for each refinery/crude combination. (For purposes of this exercise we will ignore the situation for all the refinery products other than gasoline and diesel oils.) Your task is to 1) explain what has caused prices to increase so much even though there is still spare crude and refining capacity, and 2) explain what actions the refining industry could have taken prior to Year 4 that might have avoided the large price increases.
