The oil ministry continues to negotiate short-term , no-bid contracts with several u.s. and european oil companies , including exxon mobil corp. , royal dutch shell , total sa , chevron corp. and bp .
Petrobras and petronas are most powerful as examples of national energy groups that have managed to pick up the know-how and become competitors to the likes of bp , royal dutch shell and chevron texaco around the world .
Late last year chevron , shell and exxon agreed to spend $ 37 billion to develop the gorgon field off australia , another potentially huge source of gas .
According to the opinion of chevron , the fire protection scheme will be adjusted later in reference to the relevant codes of chevron and in accordance with the requirements specified in the study report on fire blast in plant area , so as to meet a stricter fire protection requirement .
In short order , chevron convinced cnooc that the u. s. congress would oppose the sale and got it to drop its $ 19 billion bid .
在短期内,雪佛兰就使中海油确信美国国会将反对这项交易,并使之放弃了它190亿美元的竞价。
Unless maximum practical chevron surface area has been installed , no steam separation efficiency credit shall be allowed for the mesh added to the inlet of the chevrons .
