Around this time last year, after a number of requests, I posted the top ten questions I asked when looking at an oil and gas company.  But earlier in the year, I was asked if I would post up a more comprehensive list.  Therefore here is the full list for the questions I normally ask when looking at an oil and gas company.  Just to note, I use these on all resource companies, I just change the oil/gas to the relevant resource.  Taking diamonds for example (measured in carats per tonne):  P90 = Reserves/Probable, P50 = Indicated Resources, and P10 = Inferred Resources.  You also have to take into account JORC compliant, and non-JORC compliant; Russian C1, C2, etc, and others.  But that is not for this article.  Getting back on track, here are the main questions I ask:

1) Do they have reserves, resources or a mixture of both?  Reserves are the most valuable, Contingent the second most, and Prospective the least.  If they have reserves:

a) How many 1P/P90 and 2P/P50 do they have?

b) Do they have any 3P/P10?

If they have resources:

a) What is the low estimate, median estimate, and high estimate of the recoverable resources, or the OIP/GIP (Oil/Gas in place) numbers?

2) What is their exploration upside?  And what are the odds of success?

3) Is the prospect conventional or unconventional? Conventional is lower cost and less risk.

4) What is the oils API rating? This is imperative when working out the worth of an oil field as it dictates the likely sale price that they will be able to attain for the oil. An API of <10 is extra heavy, 10-25 is heavy, 25-30 is medium heavy, 30-40 is intermediate, 40-50 is light, and anything above 50 is extra light. Most oil fields are intermediate (though some like to call their crude light anyway like Saudi Arabia), with the two bench mark oil prices -- Brent Crude and Western Texas Intermediate (WTI) -- being intermediate. This means that anything lower than a 30 API will require a discount from the oil price. For an API of 14, discounts can start high as 20-25% before dropping down, whilst some can be as low as 5-7%.  It is totally dependent on how the refineries rate the quality of the oil, also, how strong the demand for oil is at current.
