Abstract: The Damintun (大民屯) depression, a small (about 800 km2 in area) subunit in the Bohai (渤海) Bay basin, hosts nearly 2?108 t of high-wax oils with wax contents up to 60%. The high-wax oils have high consolidation temperatures and viscosities. The high-wax oils were generated from the fourth member of the Shahejie Formation (Es4), which is also important source rocks for oils in other subunits of the Bohai Bay basin. Yet high-wax oils have not been found in significant volumes elsewhere in the Bohai Bay basin...
