Organic geochemical and basin modeling methods were used to investigate the potential of thermogenic gas
generation from the source rock of the Miocene Salif Formation. The analyzed Salif shales were collected close to
the intrusive volcanic rocks intersected by the Kathib-01 well in the offshore Tihamah Basin, Yemeni Red Sea.
Generally, the analyzed Salif shale samples have total organic matter (TOC) values up to 3.4 wt %, overall,
indicating organic matter richness capable of generating hydrocarbons. The analyzed Salif shale samples have
low hydrogen index (HI) values of 1.35% Ro) with a transformation
ratio (TR) above 99%. The prediction of a significant charge of thermogenic gas generation from the
Salif Formation in the studied Kathib-01 well is due to the presence of the volcanic intrusive rocks extruded
during the late Pliocene to present day time
