US shale producers are seeking to deploy their expertise around hydraulic fracturing in international markets, in a marked departure from their recent strategy and one that is set to accelerate as domestic output slows.
Continental Resources — whose billionaire founder and executive chairman Harold Hamm was one of the driving forces behind the shale revolution after figuring out how to unlock the vast resources of North Dakota's Bakken basin with horizontal drilling — recently announced plans to explore for unconventional resources in Turkey. And EOG Resources aims to kick-start a drilling campaign in Bahrain.
Early successes could prompt a scramble by peers to follow suit, which would be a reversal of the trend seen in the early days of the shale boom when the industry largely retrenched from overseas investments to concentrate on exploiting domestic plays. And while decisions to venture abroad have been mainly based on individual company strategies up until now — and investors have been lukewarm at best — forecasts for shale to start plateauing in the coming years could lend them greater impetus. "Maybe, as they have success, that will draw others in," energy investment firm Bison Interests chief investment officer and founder Josh Young says. "It could be the start of something big."
The caveat is that a potential international push at scale is unlikely to happen overnight, and companies such as Murphy Oil and APA — which already have exploration campaigns under way from Vietnam to Ivory Coast and Suriname — have underperformed compared with their rivals. "You are not seeing that market acceptance or market credit for international projects," Young says.
That perception may shift if international exploration yields above-average returns for shareholders, boosting the case for producers to seek to build out their inventory further afield as growth in the shale patch slowly grinds to a halt.
International exploration may have its own risks, given shale's success story has largely been confined to the US and Argentina to date. But the "cost of entry is relatively low compared to a North American landscape with little room for exploration and high premiums for solid assets in the Permian", consultancy Rystad Energy vice-president for North America oil and gas Matthew Bernstein says.
Hamm, who took Continental private more than two years ago after tiring of public markets, recently warned that US shale is beginning to plateau. "What we really need to concentrate on is where we go as we crest right here in America, what the downside looks like," he told the CERAWeek by S&P Global conference in Houston. He also signalled a greater openness to drill outside North America.
Talking Turkey
Continental recently announced a joint venture with Turkey's national oil company and US-based TransAtlantic Petroleum to develop oil and gas resources in southeast and northwest Turkey. State-owned Turkish Petroleum has pegged initial estimates from the Diyarbakir basin in the southeast that could reach 6bn bl of oil and 12 trillion-20 trillion ft³ (340bn-570bn m³) of gas. The Thrace basin in northwest Turkey may hold up to 20 trillion-45 trillion ft³. "We see immense potential in Turkey's untapped resources," Continental's chief executive, Doug Lawler, says.
And in February, EOG Resources announced a tie-in with state-owned Bapco Energies to evaluate a gas prospect in Bahrain. EOG will take on the role of operator, and the venture is awaiting further government approvals. "The formation has previously been tested using horizontal technology, delivering positive results," EOG chief executive Ezra Yacob says. By deploying its existing skillset around horizontal drilling and completions, EOG is confident of achieving results that are competitive with projects in its domestic portfolio.
