Investopedia defines “Barrel of Oil Equivalent (BOE) as the amount of energy that is equivalent to the amount of energy found in a barrel of crude oil. There are 42 gallons in one barrel of oil, which will contain approximately 5.8 million British Thermal Units (MBtus) or 1,700 kilowatt hours (kWh). (The use of BBOE is the same with the double “B” indicating the plural of barrel.)
So when I read a pronouncement that a company has wells that are capable of making 1 MMBOE, what does that mean? It means they say the well will make 1,000,000 barrels of oil…equivalent.
So what is equivalency? Equal to what? It means that the combined oil and gas in the well should be equal to the energy in 1,000,000 barrels of oil. The key word is “should”. In fact, the well might not produce a shingle barrel of oil. We could convert all the natural gas and natural gas liquids into “oil” metrics.
Natural gas contains about the same amount of energy in a 5,800 – 6,000 CFG (cubic feet of gas) as one barrel of oil. It actually varies according to gas quality. And “liquids” (ethane, propane, etc.) generally enhance the energy levels. So a typical metric suggests using 5,800. So you can see that a well of pure natural gas has the same energy as if the well produced about 172,000 barrels of oil.
So when a company claims that they have a 1 MMBOE well, it is going to be partly oil, partly gas, And if it was 100% methane, then it is the same as saying the well will make 5.8 BCF (billion cubic feet) of gas. Gas is sold in 1,000 cu. ft. (MCF) units. Currently a lot of gas is sold for under $2, but for argument sake let’s say $2. And oil (as bad as it seems) is selling for ~$35 a barrel.
There is something wrong with that picture. Do you see it? The ratio by energy or BTU content between oil and gas is 5.8 , let’s say 6. 6 MCF = 1 BO. But if we multiply $2 by 6 we get only $12. Oil should sell for $12 a barrel…a third its actual price. Natural gas is badly undervalued and has been for the past decade with the advent of horizontal drilling.
So you think your 1 MMBOE well is worth $35/bbl x 1,000,000 or $35,000,000. But if the well is 50% gas and 50% oil, think again. Yes, 500,000 oil barrels are valued at $17,500,000 but the gas equivalency is 500,000 barrels of oil, and 500,000 x 6,000 or 3 BCF, and that is $2 x 3,000,000 or $6,000,000.
The duplicity is in the disconnect between the ratio of prices for oil and gas, and the actual percentage of oil and gas in a given well. Your $35,000,000 well may be only $23,500,000 if 50% of the production is gas, and if all gas, it would be a mere $12,000,000…which is less than the find cost, drilling cost, and production cost of a well in most of the deeper basins. One more hint. Most wells in these shale plays are making less than 50% oil but are often called “oil wells” when they are producing both gas and oil.
Perhaps next time we will talk about the cost of disposing of waste water from wells, the giant elephant in the Shale room.
