The company, which already holds interests in blocks in Kenya, Republic of Guinea and is waiting to finalise a PSC for Block 3 in Mali, signed contract on the three blocks, Monday.
Simba also has applications pending for blocks in Liberia and Ghana.
Hassan Hassan, the company’s managing director in charge of operations, said Simba will hold 100% stakes in the three concessions in Chad, each of which could be “a company-maker in its own right”.
Two of the blocks, Chari Sud Block I and Chari Sud Block II, cover a total area of more than 10,000 square kilometres and are located south of the Mangara and Badila oilfields being developed by Griffiths Energy and Glencore International.
The pair of concessions, located in the southern margins of the Doba and Doseo basins, are believed to have structural similarities to the producing fields, while pipeline infrastructure is located in the vicinity of Chari Sud Block I.
The third concession, Erdis Block III, spans 15,700 square kilometres in the Erdis basin where numerous oil discoveries have been made to the north in Libya, where it is called the Kufra basin.
