Study of heterogeneity of reservoir properties in the assessment of the geological structure and reserves calculation of fields of Vietsovpetro JV

Vietsovpetro JV conducts exploration and development of hydrocarbon fields on the continental shelf of Vietnam. The following fields were put into development at block 09-1: White Tiger, Dragon, White Bear, White Hare and Southern Dragon-Sea Turtle. During production a detailed study of the geologic...

The following fields were put into development at block 09-1: White Tiger, Dragon, White Bear, White Hare and Southern Dragon-Sea Turtle.
