Shale to emerge leaner from M&A boom

The recent flurry of deals in the US shale patch is poised to deliver significant productivity gains, potentially offsetting a drilling slowdown and suggesting that it might well be a mistake to bet against the sector any time soon.

Ownership of top shale basins, such as the Permian in west Texas and New Mexico, is increasingly falling into the hands of fewer but larger operators, with the necessary resources to chase technology breakthroughs and drive economies of scale that could support further output growth. The flood of deal-making comes as shale growth is likely to slow after defying all expectations last year.

Even as acquirers look to fine-tune their combined portfolios and slow activity in favour of shareholder returns, they will still be targeting ever longer lateral wells that reduce the need for more rigs and hydraulic fracturing (fracking) crews. Fracking multiple wells at the same time and shifting to electric fleets will also help them become more efficient. All in all, shale could continue to be a thorn in Opec's side for years to come. Underestimate US shale at your peril was the title of a recent report from analysts at bank HSBC. "We expect the mergers and acquisitions to result in substantial capital efficiencies," they wrote.

Concentrated operations have reduced inefficiencies in the supply chain, and the elimination of downtime has also helped producers become leaner, according to consultancy Wood Mackenzie. But costs remain 15-30pc higher than 2020-21 levels, suggesting scope for further improvements. And while efficiency gains will inevitably become exhausted at some point, opportunities to tackle unproductive processes might still crop up. "The will and the technology are there for some operators, who should be able to keep cutting capex while modestly growing and maintaining shareholder distributions for a while to come," Wood Mackenzie research director for the Lower 48 Maria Peacock says.

ExxonMobil flagged $2bn in annual savings from its $64.5bn takeover of shale giant Pioneer, with two-thirds to come from improved resource recovery and the rest from efficiencies. Leading US independent ConocoPhillips says improved technology will help it extend its inventory of top-quality drilling locations in both the Eagle Ford and Bakken basins after its $22.5bn tie-up with Marathon Oil.

Return to spender

Productivity gains are hardly the preserve of firms that have been active participants in the $200bn of shale deals seen over the past year. For example, US independent EOG, which has sat out the mergers and acquisitions (M&A) boom so far, plans to deliver the same level of growth for this year as seen in 2023 with four fewer rigs and two fewer fracking fleets. "Technology has evolved so much that you can go and drill horizontal wells in these and exploit that technology and you can get just absolutely outstanding returns," chief operating officer Jeff Leitzell says.

Still, almost half of oil and gas executives recently polled by the Dallas Federal Reserve think that US oil output will be "slightly lower" if consolidation continues over the next five years. But the answer differed by company size. All executives from E&P firms that produce 100,000 b/d or more envisaged "no impact".

Service company executives are more concerned: "Consolidation by E&P firms has curtailed investment in exploration," one said. "Our hope is that it's a temporary situation that will work itself out as the integration is completed."

And even though the prolific Permian basin is due to peak before the end of the decade, analysts forecast robust growth in the intervening years. Relatively high oil prices that remain above breakeven costs and efficiency gains — which will shift the mix of wells to newer and more productive ones — will be the main drivers, according to bank Goldman Sachs.
