Hey onco, the reporting, tracking, listing, selling, etc. of oil is not a simple process or even remotely straightforward. You would think it would be but it is not. It is difficult to explain and I'm not familiar with it enough to be able to explain it "logically" so to speak. LOL
Just as an example, that site shows 585 production for three months yet take a look Hemi's Feb 27th PR they state right there they produced 669 bbls in just January!
Basically though, the numbers listed aren't a true reflection of the production of any small oil company listed on there. Even their footnote indicates such "*2008 data incomplete at this time. Data from previous years may still change." Heck, we are over 1/2 way through 2008 and they even indicate that data from previous years may change. LOL
And to answer your question in another way. They are able to stay cash flow positive from the production of oil, even if not stellar, by...
1) Keeping expenses low.
2) No shifty toxic type financing deals with 2nd, 3rd, or even 4th parties as so many small oil companies do.
3) 100% working interest in their leases (another indication of no financing deals that might be considered detrimental to the investor)
4) 80% or better royalty interest.
5) No massive interest payments due to large debt as is the case with many small oil companies.
So, by building the business the way Keith did, even with lower production numbers, Hemi is actually better off than other oil companies with ten times the production. The beauty of this entire "thing" is that very good production is right around the corner but Hemi won't have all the "crap" that normally goes with good production from a small oil company.
