Time for the (belated) year-end review.
2012 Year-End Review------------------------------------
------------------------------------
Discovery With Oil-In-Place Amounts------------------------------------
------------------------------------
In 2009 and 2010 I cataloged a total of 2.7 - 5.7 billion barrels OIP in this one. It's now up to 12.4 - 15 billion barrels OIP. So I'll add 9.3 - 9.7 billion barrels OIP to this year's catalog.

Last year I cataloged two seperate entries of 150 million and 545 million barrels in this formation. New out today is that YPF/Repsol's evaluation is up to a total of almost 23 billion boe. Parsing the press release, it looks like a lot of that is gas, and Repsol/YPF don't have leaseholds in the entire area, so the oil-only net-to-Repsol total is considerably less. There are 6 different categories of reserves in the press release, and as often noted in this thread I'm not here to catalog P1 - P3 reserves (unless that's the only thing I can get). The category here which seem most appropriate for "discovery" status seems to be "Contingent Resources," whose definition can be found
here (PDF) and in the narrative to the press release (last page) which, indeed, are potentially recoverable reserves from discovered (known) resources:
Contingent Resource.
Contingent Resources are those quantities of petroleum which are estimated, on a given date, to be potentially recoverable from known accumulations, but which are not currently considered to be commercially recoverable ...
Since I only catalog discovered accumulations in ownership of a company, the contingent resource would be the one net to Respol/YPF. The oil-only number for that is 883 million barrels. Subtracting last year's entries leaves us 188 million barrels.
Size of discovery:
188 million barrels recoverableDate: February 8, 2012
Company(s): Repsol YPF

In April 2010 I cataloged 690 million barrels of this. They've since added to it. Page 20 of the link (PDF) says they're now at 1.136 billion barrels (oil only). So 1136 - 690 = 446 million barrels for this entry.

This one says 600+ million BOE on pg. 25 of the link, and it says the liquids composition is 65%. Doesn't say how much of that is oil, condensate and NGL's, but at least it eliminates the dry gas portion of the BOE

Company(s): Anadarko Petroleum Corp.
Name: Anadarko Eagle Ford Shale acreage

Estimated production startup date: Ongoing production startup
LINK (PDF, pg 25)
------------------------------------
On page 35 of the link we've got Anadarko's Permian Basin holdings categorized into 2 zones:
Avalon: 400 million BOE is 15% oil = 60 million barrels oil only
Bone Spring: 400 million BOE is 70% oil = 280 million barrels oil only
-----------
Total is 340 million barrels
Size of discovery:
340 million barrels recoverable oilDate: March 13, 2012
Company(s): Anadarko Petroleum Corporation
Name: Anadarko Permian Basin acreage (Avalon and Bone Spring)
Location: West Texas
API: light oil
Flow rate of test well(s): few hundred bpd to over 1,000 bpd
Estimated production startup date: Ongoing production startup
LINK (PDF, pg 35)
------------------------------------
On pages 43 & 49 of the link we've got Anadarko's Wattenburg/Niobrara Shale acreages. Page 43 says the total net resources is 500 million - 1.5 billion barrels. Page 49 says the typical well in the play will produce 60% oil.
So this gives us a range of 300-900 million barrels of oil-only.

In June 2010 I cataloged 242 million barrels for this one. Now they're giving a middle estimate of 355.6 million barrels (rounded up to 356). Subtract 242 from that and this year we get an addition of 144 million barrels.

Here's more of the weird Iranian announcements. Not much detail, but the link says:
The official added that the actual amount of oil and condensate discovered last year exceeds 2.87 billion barrels ...
Given my policy for adding to the catalog in the year they're announced, they're going in this year rather than last year.
Last year I *did* catalog one named Iranian discovery named "Khayyam" which was 170 million barrels, so just in case their total announced today includes that, I'll subtract it from the amount announced today.
Since these are being called "reserves" I presume they're recoverable amounts.
