Annual Reserve Revisions Part III: Larger Independents

The story here is of a gradual decline in the size and importance of most of these (once) large independents. Their combined reserves and production is not sizeable compared to the super majors and majors but their history may be indicative of what is coming the way of the larger companies. All but one of these companies is American owned. Most have or had holdings in shale or oil sands but many have sold off most of these and chosen to concentrate on a shrinking core business. There is probably a fuller picture to see if their financial performances, such as debt loads or share buy back schemes, were also considered but that’s a bigger job than I’m prepared for or capable of.

Annual Reserve Revisions Part II: International Major IOCs

There’s not much revelatory here, more a completist’s list showing reserve changes for seven IOCs, with more to come over the next months, but it gives me an excuse for a rant at the end.

There are a few general trends but exceptions to each one. As discoveries have dropped production has been maintained, presumably through in-fill drilling and other brownfield activities – this can’t be construed from the data shown, although deeper analysis of the annual reports such as looking at drilling activities and financial details might be able to give further insight. Therefore remaining reserves have fallen as have reserve to production (R/P) ratios. Replacement ratios have been at or just below 100% and seem to be dropping faster – i.e. depletion is accelerating and actually seems to be particularly pronounced in recent years (acceleration of acceleration is called jerk or jounce I think). Looking at individual companies doesn’t give the full picture because of purchases and sales, but there is less of that than I expected for the companies shown here. A fuller picture might come when combining all the larger companies but even then it will not be complete. The recovery ratios are show for the organic numbers (i.e. without the net trades) as solid lines and trend lines with overall ratios shown as marker points.
