oa The Upper Triassic Minjur Formation: A New Bio- and Sequence Stratigraphic Framework and Its Implications for Hydrocarbon Prospectivity

The Upper Triassic (Norian to Rhaetian) Minjur Formation is a siliciclastic succession present at surface<br>and also in the subsurface across large parts of central and southern Saudi Arabia. Until recently its<br>stratigraphy and sedimentology have been poorly understood and it has largely been ignored as a<br>target for hydrocarbon exploration. A recent study by the Area Exploration Department of Saudi<br>Aramco built a regional bio- and sequence stratigraphic framework to support regional exploration<br>efforts in Central Arabia and better understand its prospectivity. This study utilizes core and cuttings<br>data from 26 wells, combined with wireline logs from an additional 100 wells. It should be noted that<br>all 600 ft of available Minjur Formation core in Saudi Arabia was studied.
