Reservoir zonation sequences of the Asmari Formation according to lithological alteration in the studied well-A employing core, cutting, and log data. Out of the total of 5 investigated zones, in zones 2 (3560–3444.5 m) and 4 (3585–35,705 m), it was not possible to coring because of the lost circulation, and only the data of the drilling cuttings, and log were used. Zone 1 includes anhydrite (pink color), dolomite (purple color), and limestone (blue color), Zone 2 includes dolomite and sandstone (yellow color), Zone 3 mainly includes sandstone, shale and limestone, Zone 4 includes limestone and Ahwaz sandstone, and finally, zone 5 contains mainly sandstone and limestone..
