The U.S. shale resurgence has been one of the main themes in oil markets this year, while OPEC’s production cut deal to deplete the oil overhang and boost oil prices has been the other key development in 2017.
U.S. shale production is expected to grow over the next few years as the companies that survived the worst of the downturn showed resilience in the face of the lower-for-longer oil prices. But three years of low oil prices also led to the global oil industry slashing investments in conventional oil exploration, and deferring or revisiting development plans.
This has led to the lowest ever volumes of oil discoveries in 2017, Rystad Energy said last week. While the low level of discoveries is not an immediate threat to global oil supply, it could become such ten years down the road, according to Rystad Energy.
In ten years’ time, U.S. shale production may have peaked, at least according to OPEC that sees shale peaking after 2025, although the cartel has conceded that U.S. tight oil has defied previous forecasts and has increased production more than initially expected and will continue to do so in the short term.
This year has seen less than 7 billion barrels of oil equivalent discovered globally, a volume as low as last seen in the 1940s, Rystad Energy has estimated. What worries analysts the most is the fact that this year the reserve replacement ratio—the amount of discovered resources relative to the amount of production—was a mere 11 percent, compared to 50 percent in 2012, Sonia Mladá Passos, Senior Analyst at Rystad Energy, said.
Another point of concern is that the resources discovered per field also dropped, and this could affect the commercial viability of new discoveries.
