bluesafari,
Maybe an indigenous (not a real word by the way !) oil company ? I haven't heard of any multinationals changing loyalties apart from a possible move by Chevron. Glory are definitely new to the game, along with Genesis.
The OAS/ADA AW139 is doing ad hoc work and some bits and bobs for indigenous companies. As I recall Total don't like their eggs in one basket and always spread the love (or hassle, stress and unreasonable demands) between companies; maybe they're using it when their other resources are stretched/unserviceable etc ?
Possible changes in the pipeline at a very senior level in BHNL; can't confirm.
All this is why I miss Nigeria; anything and everything is possible, even the improbable and implausible !
Cheers,
NEO
