I'm looking for international oil companies with hydrocarbon gas injection experiences in oilfields.
BP (ARCO) (Alaska), Statoil (North Sea), ConocoPhillips, Shell, Texaco (now Chevron), ARAMCO, PDVSA, AbuDabi, Co. You can also check www.OnePetro.com for more information. There are plenty of SPE and IPTC papers related to this subject
All major companies (including Total) and more than a few lower sized companies will qualify. In screening fields pay attention to the fact that nowadays gas is sometimes re-injected primarily in order to avoir flaring rather than for improving recovery. It was not/substantially less the case before, I would say, end 90s early 2000s.
@Pierre Bergey
I agree with you in that nowadays regulations limit flaring level for environmental purposes, that's why the companies re-inject some quantity of produced gas to comply with those regulation and avoid paying penalties.
I just want say that this technique isn't used in gas fields but it is used in oil fields that have a big GOR.
The reason is that most oil fields are not equipped with adequate gas treatment facilities, and nearly all of them are not linked to the main gas pipelines.
@Hadi Bagherzadeh
Just make a search in SPE, IEEE, Elsevier and Springer. I'm sure you are going to find lot of case studies.
One thing to know is that most oil fields use water injection as secondary EOR technique.
