RIO DE JANEIRO - Brazil’s national oil-industry association, IBP, released a list of suggestions for regulatory changes on Monday that it hopes will boost exploration activity in the wake of falling oil prices, high costs, delays and a graft scandal at state-run oil company Petrobras. IBP President Jose Camargo told reporters he hopes the changes can be written into rules in time for an auction of oil concessions planned for October. The proposals focus on Brazil’s national-content regulations, which the government has strengthened in recent years in an attempt to use new oil development to create high-paying industrial jobs. Many companies, including Petroleo Brasileiro SA , as Petrobras is formally known, have blamed the Brazil-content rules for soaring costs, project delays and bureaucratic rigidity that makes compliance difficult. “We need to restart investment,” IBP Executive Secretary Antonio Guimarães told reporters at an event in Rio de Janeiro. “We’ve all seen the paralysis that we have today.” Among the IBP’s recommendations is that the government set fixed national-content levels in the contracts of winning bidders, but allow those levels to be adjusted when field development plans are submitted. This would allow flexibility in cases where certain types of equipment are not available in Brazil, IBP said. It also called on Brazil’s oil regulator, ANP, to finish writing long-expected rules on waivers from Brazil-content rules. At present companies eligible for them can’t get them, even when local suppliers are not available. ANP board member Florival Carvalho told reporters at the event that the agency is considering some improvements for the October auction, but that there would probably not be any major changes to existing rules at that time. IBP also asked for regulations that would allow oil companies to rebalance the percentage of locally sourced goods and services during the up to 15 years it takes to find and develop oil to account for changing technology and market prices. It is also seeking a way to adjust commitments for exchange rate moves. “If the exchange rate strengthens the value of local content rises if it weakens it falls,” Guimarães said.
