Correction to: Journal of Petroleum Exploration and Production Technology https://doi.org/10.1007/s13202-018-0577-6

In the original publication, article title has been incorrectly published as “Aptian–Albian oil shale unconventional system as registration of Cretaceous oceanic anoxic sub-events in the southern Tethys (Bir M’Cherga basin, Tunisia)” instead of Aptian–Albian shale oil unconventional system as registration of Cretaceous oceanic anoxic sub-events in the southern Tethys (Bir M’Cherga basin, Tunisia). Also the part of Fig. 3 caption has been incorrectly added to Fig. 4 caption. The corrected figures captions are given here.
