In 2004 the National Tresury Secretary received approximately R$ 11,1 billion under the designation of oil public revenues, classified according to the legislation in force as governmental participation (PGs) in the final economic results of oil and gas exploratory and production activities. In order to better understand the significance of these economic resources it's worth noting that that figure was higher than the federal government's investments in 2004, which summed up R$ 10,87 billion. That ammount was ditributed in the following way: 38,7% to federal government, 32,9% to provincial governments and 28,4% to local administrations.The magnitude of such revenues per si would justify an assessment of how they have been distributed and apllied thoughtout the years. Its limited sources turn its assessment even more urgent. The present study has two aims: i) to show that it's been created an artificial atmosphere that favours overinvestment and spacial concentration of public revenues in regions oil production due to a strong physical determinism of the rules used to guide the income distribution (such determinism, it ought to be said, is based on the oil fields proximity to states and cities); ii) to offer tools with which an alternative distribution and apllication regime could be designed, so that inequalities regarding the income spacial distribution as well as the inappropriate use of these valuable public funds could be minimized.
