Case Study: Oil Production Increases by 238% in Chevron’s Tengiz Field

VDA system improves zonal coverage of stimulation treatments in large carbonate reservoir

Challenge: Create long-term isolation in underground gas storage (UGS) wells in area with strict environmental regulations and where surface leaks are common occurrences.

Solution: An integrated solution that included the FUTUR active set-cement technology to protect against the loss of well integrity.

Result: No surface leaks detected after completion and an excellent cement bond across the gas injection interval that is expected to last for the life of the well.
