Tengiz field

The $48.5-billion investment aims to keep the 30-year-old project in western Kazakhstan flowing for years to come.

The objective of this study was to establish an efficient optimization work flow to improve vertical and areal sweep in a sour-gas injection operation, thereby maximizing recovery under operation constraints.

Chevron said it is returning production to normal after a week of antigovernment protests caused logistics disruptions in Kazakhstan’s principal oil-producing region, Mangastau, which borders the Caspian Sea.

This work presents a methodology to construct a sector model for the Tengiz field that covers one-sixth of the field area to evaluate improved-/enhanced-oil-recovery (IOR/EOR) processes to increase oil recovery through the life of the field.
