Cynic,
That reminds me that I wanted to mention to you the difference between resources and reserves (since you raised an issue related thereto a few weeks back).
As I understand it, resources are the expected volumes of hydrocarbons in a prospect. Resources are an estimate based on seismic and other data.
Resources are converted into reserves when the company has confirmed that hydrocarbons are in place and that they are accessible in such a fashion as to be commercially viable. This means that drilling is required to prove that the stuff is there in the first place. It is also dependent upon the oil price, as obviously a lot more oil is commercially viable if oil goes to $100 than if it slumps back to $25. For this reason, companies will occasionally release a reserves upgrade based on a sustained change in the oil price, as NOP did a couple of weeks ago.
Neither resources nor reserves appear to me to indicate the true amount of hydrocarbons present in the ground, which obviously nobody can ever really know.
VOG has strong resources - i.e. a lot of prospective territory which, according to seismic could, possibly, hopefully, maybe, yield 1 bln bboe.
However, its reserves at West Med are presently nothing much, because reserves depend upon the company successfully locating commercial hydrocarbons, which they obviously did not do at Danniella. VOG has a lot more drilling to do! If the whole area turns out to be uncommercial (perish the thought!), then reserves will be nil, even though a proven resource is in plce which may one day turn out to be commercially viable if prices continue to increase.
Don't be misled by some articles which use the vocabulary interchangeably.
I tried to confirm the difference using the very useful OSHA Glossary of Petroleum Industry Terms
GO THERE
but they only had the definition of reserves.
reserves n pl: the unproduced but recoverable oil or gas in a formation that has been proved by production.
Hope this helps. Any experts out there are welcome to correct me if I've got this wrong.
