There are around 12 crude oil qualities  which can be marketed by the Oil and Gas Marketing Team.

Shell Frontier Oil and Gas's Oil and Gas  marketing team is based in Texas and is responsible for overseeing crude marketing for the group. Crude oil volumes available for Shell Frontier Oil and Gas to market are around 160,000 bopd or 60 million bbl per year.

The team regularly issues tenders either for SPOT sales (e.g. Wytch Farm, Yombo, Vasconia, Kole) or 6 month to one year TERM sales (e.g. Coco, Oguendjo, Zarzaitine, Lucina, Xan Coban). Some other crudes are sold through long term sales agreements.

Note that Vietnamese Rang Dong and Su Tu Den crudes are marketed by PVoil through independent tenders.
