Where can I find, what oil and gas is worth when it comes out of a well head? Where can I research how much oil and gas has been removed from a well head?
What oil and gas is worth at a well head is a pretty complex question. Quality of the oil/gas as well as how it has to be transported affects what its worth. For example, gas with no pipeline is essentially worthless.
In Texas, the RRC Production Data Query is the simplest free tool to use to see what has been withdrawn from a lease or unit: http://webapps2.rrc.state.tx.us/EWA/ewaPdqMain.do Its not the greatest tool when there are multiple wells on a lease, but its a start.
Can multiple grades of oil come out of the same well head each month?
In regard to multiple grades out of the same wellhead, not that I'm aware of. Trying to determine a wellhead price is like tilting at windmills. Depends on the location of the wellhead. Depends on the API gravity of the crude. The amount of H2S and other impurities that cost to remove. Depends on how much it cost to get it to a sales point - available pipeline capacity or tanker truck. Depends on whether you want the hedged price or the un-hedged price (spot or monthly settlement price). The variable are not endless but many.
True Texan -
A slightly different take on Skip's response. In general, a well will only produce a single grade of "oil" in a given month. There are certain circumstances with with down hole commingling, that might allow a well to produce grades of oil that differ, but its coming up a single pipe. I'm not a revenue/production accountant, so I'm not sure how that would look. In addition to "oil" wells can also produce natural gas liquids which would require (generally) off-site chilling and handling to capture/sell. Again, how that is handled on a pay stub is not within my pay grade.
shelby, did you inadvertently post your reply twice? I ask because the site seems to be experiencing some glitches today.
