AUREP is the Department responsible for the promotion of petroleum exploration under the MinistÃ¨re des Mines of Mali. As of March 2016, AUREP had finalized a new division of the country in exploration acreage blocks. The old open block limits and denominations are not valid any more. The release of the new block limits was contingent on the new petroleum bill to be passed into law. The list of new acreage blocks became available in late-November 2016, it is presented below.  In the west of the country, the new blocks are smaller than the previous ones. In fact the old blocks were divided in two in this area. The amount of available seismic data has doubled between 2004 and 2014, this has translated into a better understanding of the geology of the various sedimentary basins in the country. Therefore it was possible to design new block limits that take into account the improved basin definition. A new block, NÂ° 29, was added in the far south of the country.  AUREP stands for AUtorite pour la REcherche Petroliere.

There are thirty-eight open blocks.  There were no changes from the previous list.  Total open acreage amounts to 823,822 sq km all onshore.
