Sept. 28, 1992

Anne K. Rhodes Refining/Petrochemical Editor Updated assays are now available for two crudes from Saudi Arabia: Arabian Medium - Offshore, Zuluf/Marjan and Arabian Medium - Khursaniyah/Abu Safah. The new assays show lower API gravities than previously published (OGJ, Apr. 11, 1983, p. 71). Both crudes have decreased in gravity by 2.3 API: the Zuluf/Marjan variety from 31.1 to 28.8, and Khursaniyah/Abu Safah, from 30.8 to 28.5.

Updated assays are now available for two crudes from Saudi Arabia: Arabian Medium - Offshore, Zuluf/Marjan and Arabian Medium - Khursaniyah/Abu Safah.

The new assays show lower API gravities than previously published (OGJ, Apr. 11, 1983, p. 71). Both crudes have decreased in gravity by 2.3 API: the Zuluf/Marjan variety from 31.1 to 28.8, and Khursaniyah/Abu Safah, from 30.8 to 28.5.

In addition, the sulfur content of Khursaniyah/Abu Safah has increased from 2.40 wt % to 2.85 wt %, while that of the offshore crude has remained essentially unchanged.

These latest assays were performed in 3rd Quarter 1991 for Arab Medium - Offshore, Zuluf/Marjan, and in 3rd Quarter 1988 for Arab Medium-Khursaniyah/Abu Safah.
