Drilling sample thin sections of the Asmari Formation sandstone zones in Mansouri field include (a) without cement sandstone due to migrating hydrocarbons before cementing (loose quartz grain/medium-coarse grain sub-rounded-rounded (XPL)), (b) dissolution in sandstones (quartz/ medium-coarse grain, subangular), (c) dolomite cement in sandstones (unmatured quartz/ fine grain-coarse grain/sub-rounded-subangular), (d) dolomite dissolution in sandstones (quartz grain/ medium-coarse grain, subrounded).
