Last month, David Rubenstein, a founder of private-equity firm Carlyle Group, said he anticipates “maybe the greatest energy investing opportunities we’ve ever seen.” Marc Lasry, founder of hedge fund Avenue Capital, has described energy as a “once-in-a-lifetime opportunity.”

Eni has already developed phases 4 and 5 of the South Pars gas field as well as two phases of Darkhovin oilfield. It has shown interest in developing Iran’s North Pars gas field and also the third phase of Darkhovin oilfield.

The Canadian Association of Petroleum Producers, which represents the industry, forecast that it would invest C$42bn (US$29.5bn) this year, 13 per cent less than last year and 48 per cent less than in 2014. That is a steeper decline than investment in oil and gas production worldwide, which is expected to drop by 40 per cent over 2014-16, according to Wood Mackenzie, the energy research company.

Investors have pulled billions from US stock funds for the third straight week amid sharp market gyrations, which have frayed investor nerves as global equity bourses slid deeper into correction territory.

“Companies have to be prudent in the face of what’s happening,” says Daniel Yergin, vice-chairman of consultancy IHS. “It’s a wrenching period for the industry.”

Iran needs $20bn to develop the remaining phases of the South Pars gas field, energy minister Bijan Namdar Zanganeh said

The IPO proposal is consistent with the broader direction of economic reform in the kingdom, including state asset sales and market deregulation, Aramco said. Bringing in investors would also strengthen the company’s focus on long-term growth and the prudent management of its reserves, according to the statement.

Even if E&P clients are able to negotiate more favorable terms for their debt, the industry’s overextended balance sheets will put a cap on activity — even if oil prices rise. On the producer side, companies will most likely de-lever before they drill should some extra cash come in the door. For OFS, building all the new equipment such as walking rigs and big frac spreads to meet strong client demand has some players in this sector significantly over-levered.

West Texas Intermediate crude for February delivery declined to $36.58 a barrel on the New York Mercantile Exchange, after falling 0.8 percent Monday. U.S. crude inventories are forecast to keep supplies more than 130 million barrels above the five-year seasonal average, according to a Bloomberg survey before government data Wednesday.

While tens of thousands of jobs have already been cut in 2015, more redundancies are expected this year as companies narrow their focus.

Moody’s last month also projected average prices of West Texas Intermediate crude at $40/bbl in 2016, $45/bbl in 2017, and $50/bbl in 2018. The 2016 price is down $8/bbl from the firm’s earlier forecast.

With no growth and no profits, the US exploration and production industry is facing a gruelling year. The gap between strong and weak companies is likely to widen. Those that have lower-cost production and healthier balance sheets should be able to stay in business. Those that have good assets but big debts may have to sell their most valuable properties. Those that have neither attractive assets nor strong finances will be heading for bankruptcy.

Iran needs $100 billion to rebuild its gas industry and has met with European energy giants, Azizollah Ramezani, International Affairs director at NIGC said in June.

Modi and Putin hailed what they termed a “strategic partnership” at their Kremlin meeting on Thursday and pledged to boost business ties, with the Indian leader signaling progress on defense projects to ensure his country upgrades its weapons capability.

Shell has already taken action to cut costs and reduce spending this year by $12 billion, but Tuesday’s announcement of a $33 billion target for next year is $2 billion below the company’s previous guidance.
