Brazil: natural gas production 2014-2019, by layer

The natural gas production from pre-salt in Brazil has more than quadrupled between 2014 and 2019, reaching nearly 26 billion cubic meters in 2019. Meanwhile, production in the post-salt layer saw a continual decrease in the indicated period.The pre-salt layer is a series of geological formations formed by the separation of what are currently the American and African continents. Pre-salt fuel reserves are normally located in deep-sea areas, under thick layers of salt. In Brazil, the exploration of pre-salt reserves started in 2006.

巴西盐层以下天然气产量在2014年至2019年间增长超过四倍，至2019年接近260亿立方米。与此同时，在盐层以上的产量在同期内持续下降。盐层以下地层是一系列由美洲和非洲大陆分离形成的地质构造。盐层以下燃料储备通常位于深海区域，深埋于厚厚的盐层之下。在巴西，盐层以下储备的勘探始于2006年。
