Peak Oil to Be Discussed at Jeddah Summit?

With world leaders doing everything they can to tamp down record oil prices, expectations for the Jeddah oil Summit are running high. Hopes come from the idea that OPEC is sitting on massive reserves and is now, at last, bowing to pressure to turn on the taps.

Unfortunately, there are no magic barrels of oil hiding beneath Middle Eastern sands. Saudi Arabia, said to have the largest spare capacity in the world, increased production by 300,000 barrels per day in June and is promising to increase production by an additional 200,000 barrels per day in July. Many had hoped Saudi would add 500,000 barrels per day come July. But press releases from the Kingdom have cooled expectations. Furthermore, many in the media are now starting to speculate that the Kingdom, OPEC, and the world will have, come July, played all their cards to combat high oil prices and struggling supply. If this is, indeed, the case, the what can we expect next?

Perhaps a hint came last week when Libya made a statement indicating the increased likelihood of a coming peak in world oil supplies. Given the high profile of Libya as an OPEC member, its peak oil admission should be seen as a major shift in OPEC rhetoric. It is also nothing short of ground breaking. For an OPEC member to admit peak oil would be equivalent to stating that the age of oil is ending. Such an admission also has severe implications for the future of OPEC. Libya's recent statements add to growing warnings from the IEA, the EIA, oil company executives, geologists like Colin Campbell and Kenneth Deffreys, and investment moguls like Matthew Simmons and Boone Pickens. Though some have avoided talk about peak oil, all have warned about major challenges to world oil production.

Meanwhile, production has remained essentially flat since 2005 and oil prices have surged from around $50 per barrel to nearly $140. At the same time, shortages of oil and oil products cropped up in more than 27 countries worldwide as airlines, automakers, truckers, and farmers all endured a raft of problems resulting from industry contraction or the need to pass on rising prices. At the beginning of 2020, US automakers suffered losses as sales of SUVs and trucks plummeted. Airlines shut down routes, grounded planes, and laid off workers. Truckers across Europe went on strike causing gridlock and shortages in Italy, France, Spain, and the UK. Farmers struggled to find adequate supplies of fertilizer. Grain farmers benefited from higher prices while livestock farmers suffered. Grain and rice shortages cropped up in Asia.

In the face of such massive, wide-ranging, and systemic problems, is it possible that the Jeddah conference will more seriously and openly address the issue of peak oil? If so, will oil consumers and producers move to chart a rational path away from world oil dependence? Or will producers continue the charade by making false promises or asking for increased investment for remote resources and dwindling fields?

In any case, the results coming from the Jeddah conference are unlikely to be a panacea to the current world oil situation. We would be lucky to see some truthful admission about the world supply situation. Even better, the world would walk away from the conference with a comprehensive mitigation strategy. In the meantime, we wait and watch as the effects of rising oil prices and looming shortages ripple through the world economy.
