American oil and gas giants ExxonMobil and Chevron canceled trips for their executives to the ADIPEC conference in Abu Dhabi in early November. The reason is growing security concerns in the Middle East, where the risk of a new military escalation remains. ExxonMobil CEO Darren Woods and Chevron Mining CEO Clay Neff were expected at the event. Now their participation has been canceled, although the forum brings together oil producing companies and investors. Both corporations refused to publicly explain the decision. The conference itself has not been canceled yet. The tension stems from the possibility of new US strikes in Iran and retaliation by Tehran. Security threats are already changing the plans of the major players in the energy market. Business contacts, negotiations and the personal presence of leaders become dependent on the military situation. The travel cancellations show how the regional conflict is disrupting the normal operations of the global oil industry.
