Are these two oil stocks the best way to play the US shale revolution?

I always suspected that last year's OPEC and non-OPEC production cuts wouldn't lift the oil price for long. Why? Because even a small increase in the price of crude was likely to open the floodgates to the second wave of the US shale oil revolution, and so it has come to pass.

Beyond the shale

The US isn't bound by any production agreement so can carry on fracking and pumping at will, and with Donald Trump in the White House, that is exactly what it is going to do. Producers in the vast Texas Permian Basin reckon they can break even at prices as low as $30 a barrel, which makes me sceptical about investing in low-margin producers in other oil sectors and regions. I have been looking for a domestic way to play shale and I wondered whether these two companies might fight the bill.

London listed engineers Amec Foster Wheeler(LSE: AMFW) and Wood Group(LSE: WG), which agreed a £2.225bn merger last week, have both made acquisitions, giving them exposure to unconventional oil and gas markets in the US. Amec paid £1.9bn for petrochemicals engineering company Foster Wheeler in 2014, while Wood Group bought PSN in 2010 for around £600m. Wood Group has also said it would support UK shale companies if fracking is allowed here, although that could take time.

Aberdeen Anguish

The two Aberdeen-based companies have been squeezed in the wider oil sector crunch. Amec Foster Wheeler has seen its share price almost halve in the past two years. Last week's update showed trading profits down from £374m to £318m, with like-for-like revenues down 8% to £5.44bn, as continuing weakness in the oil and gas market offset a strong performance in its solar division. Trading margins fell 110 basis points to 5.8%.

Wood Group has also floundered, with total revenues shrinking 15.7% in 2016 to $4.93bn, while operating profits fell 22.8% in EBITDA terms. However, its £2.2bn all-share takeover gave its shares a lift, with the new entity anticipating sustainable cost synergies of at least £110m, plus diversification benefits. Let's hope this link-up, assuming it completes, goes better than Amec's merger with Foster Wheeler, which brought shale exposure and global diversification but saddled the company with £1bn in debt.

Power down

Amec Foster Wheeler has some diversification through its engineering and installation capabilities, while Wood Group also operates in the power plant, industrial and key energy sectors. However, oil and gas remains a tough sector to be in, and I cannot see that changing.

Although both companies now have access to US shale, their exposure simply isn't enough to be a game-changer. Shale also has challenges, as salaries and costs are starting to climb as the boom gets back into gear, pushing up costs and cutting margins. Also, shale is likely to turn into a global revolution, with new production popping up everywhere, including a massive new basin in Mexico.

Boom or bust

If the merger goes through, the new entity will hold a combined 60% share of the North Sea oil services market, which is where their major interests lie. Their exposure to shale is relatively small. In fact, the shale boom, if it continues, is likely to inflict more harm than good on their wider energy interests.
