Intervention, Not Exploration: How Jack-ups Help Unlock Value

Talking about untapped value in offshore energy typically brings exploration, new wells and new developments to mind. But in today’s mature basins, the greatest source of opportunity is often neither new nor undiscovered.

Many offshore regions are defined less by exploration potential and more by declining production and ageing infrastructure. APAC is one clear example where, according to Offshore Network, the region is experiencing annual recovery declines of around 10%, with approximately 80% of basin fields now in the brownfield phase and an estimated 40–50% of well stock currently shut in, representing a striking degree of unrealised potential.

This picture has many similarities with the UK North Sea, where ageing infrastructure, rising operating costs and complex late-life economics have steadily pushed more wells into shut in status. The proportion of non-producing wells now exceeds the North Sea Transition Authority’s (NSTA) 10% target, while Wood Mackenzie estimates that around £10 billion of pre-tax value remains locked within existing wells.

Staging an Intervention

Against this backdrop, well intervention offers the fastest and lowest-cost route to restoring production from existing wells. Where production cannot be recovered, intervention also provides the only practical means of delivering permanent abandonment and removing
