'Upon closing of the transaction Jacka will join
the Joint venture consisting of YFP (Operator), Chevron (Technical Advisor), Vitol and Panoro Energy.'
according to JKA announ. (see above) YFP (the indigenous Nigerian company) are already the operator not Chevron. I would think that Chevron's technical skills will be missed though and they were probably a 'defacto' operator. sounds like there have been a few tensions between the JV partners
