Syrias proven Natural Gas reserves are estimated at 8.5 trillion cubic feet (Tcf). Most (around three quarters) of these reserves are owned by SPC, including about 3.6 Tcf in the Palmyra area, 1.6 Tcf at the al-Furat fields, 1.2 Tcf at Suwaidiyah, 0.8 Tcf at Jibsah, 0.7 Tcf at Deir ez-Zour, and the remainder at al-Hol, al-Ghona, and Marqada. About half of Syrias gas is non-associated, with the rest either associated (with Oil) or "cap" gas. In June 1999, a new natural gas field, called North al-Faydh, reportedly was discovered by SPC. The field reportedly has production potential of 35 million cubic feet per day (Mmcf/d).
