On 27 August 2007, Chad's Prime Minister M. Nouradine Delwa KassirÃ© Comakye announced that the country had promulgated legal texts and implemented mechanisms relating to the specific management of its oil incomes in order to adhere to the Extractive Industries Transparency Initiative (EITI). The Government solemnly declared that the principles of this initiative from that moment on would be applied to Chad and the incomes drawn from the extractive industries would be declared and used in total transparency.  The Al Kufra Basin is better known as Erdis Basin in Chad.   The south extension in Niger and Chad of the Murzuq Basin is called Djado Basin (or Jadu Basin) and has seen no hydrocarbon exploration in the past.  The Faya-Largeau area is poorly explored, with only a few low-quality seismic lines acquired in the 1980s.   The Lake Chad area was one of the first regions to be explored in Chad, but unlike the Doba Trough, it has not been intensively explored. Three discoveries have been made: Kanem-1 in 1974, Sedigi in 1975 and Kumia-1 in 1976.
