Aramco adds volumes to proven gas and condensate reserves at Jafurah field

Saudi Aramco has added volumes to the proven gas and condensate reserves at Jafurah unconventional onshore natural gas field in the Kingdom of Saudi Arabia.

The company has booked 15 tcf of raw gas and 2 bbl stb of condensate as proven reserves at the field. Aramco now estimates that Jafurah contains a total resource of 229 tcf of raw gas, alongside an estimated 75 bbl stb of condensate.

In a release Feb. 27, the company said the new estimates were calculated “using a novel approach to shale reserves booking, which was applied to unconventional resources for the first time in the industry and has potential to be deployed at scale.”

Further, Aramco said the reserve booking practices “were assessed through establishing continuity of resources and consistency of performance,” and that the new estimates were technically validated by industry reserves certification consultancy DeGolyer and MacNaughton, “which reviewed the statistical booking mechanism and provided a fully independent assessment.”

Work is currently under way to deliver production at Jafurah, with plans to ramp up to reach a sustainable sales gas rate of 2 bbl scfd by 2030, in addition to ‘significant’ volumes of ethane, natural gas liquids, and condensate, the company said (OGJ Online, Dec. 1, 2021).
