More actual data?

The article was created in 2008 with said the field got 58 million barrels of oil reserves left, technology (horizontal drilling, maybe also fracking?) maybe made more ressources to reserves, but in 8 years no change?! 8 years are 2920 or 2922 days, so even only 5,000 barrels per day production (which is very low of course) would be almost 15 million barrels.

Hi, yes, I'm the one who wrote the article -- I used the statistics from the California State Department of Oil, Gas, and Geothermal Resources. They update every year and the statistics need to be updated. Chevron of course would have their own estimates they do not release to the public. Antandrus (talk) 22:19, 18 April 2016 (UTC)[reply]

The US EIA requires oil companies to submit reserve data annually, by field. I'll see if they have anything available on Coalinga. Plazak (talk) 23:54, 18 April 2016 (UTC)[reply]

The US EIA publishes the List of 100 largest oil fields, as of 12-31-2013, but unfortunately, holds back the exact proved reserves of each field, listing only the sum of reserves for each group of 10 fields. Coalinga is #76, the 11th largest in California, in a group of ten with an average proved reserves of 71.3 million each. The groups above and below bracket the Coalinga reserves between 65 and 82 million BO. I'm afraid that's all we know from US EIA. Plazak (talk) 01:42, 19 April 2016 (UTC)[reply]

Thanks Plazak. I remember looking through that data some time ago, and that explains why I never used it. I can look up the latest from DOGGR but they tend to run a few years behind. Antandrus (talk) 01:50, 19 April 2016 (UTC)[reply]

Preliminary report for 2014 is out, but contains no reserve figures, alas. I think they wait until they publish the full annual reports to include those, but it looks like they haven't published one since 2009. I'm guessing they're understaffed. Antandrus (talk) 01:55, 19 April 2016 (UTC)[reply]
