Sleipner Vest is a large gas-condensate field which is produced by pressure depletion. Currently (January 2018) the best production well is B-1. B-1 is placed in a segment with very strong pressure support from aquifer. In summer 2016, it was about to water out. A straddle operation was planned and executed.

The straddle operation was very successful. More than a year later, B-1 still produced more than twice as much as any other Sleipner well. However, the water is eventually expected to come back in the remaining perforations. Concepts for crossflowing the gas and water production from the well into another reservoir has been investigated.
