with the Abu Ruweis Formation in northern Jordan.
The main reservoir in Meged is the Mohilla
‘A’ member, which consists of a porous carbonate
grainstone facies with porosities ranging between
3% to 12% and permeabilities ranging between 0.5 to
5mD. This is encountered below 4,000m in the Meged
closure and covers an area of around 180 km 2 . The
overlying anhydritic mudstones of the Mohilla ‘B’ and
‘C’ members provide the top seal over the structure.
Hydrocarbons in the Meged oil field are sourced from
the regionally present Silurian shales, as typed by oil
recovered from the Meged-2 and 4 wells.
Carbonate Build-Up Anomaly
Could there be carbonate reef play in the Triassic of
Jordan similar to that in Ma’anit in Israel? A number
of anomalous seismic features were noted within the
Triassic interval on several seismic lines during a study
undertaken for Petrel Resources in 2005. Although
there appeared to be some type of build-up within
the section against which beds at the same level abut,
it was also possible that they were merely seismic
artifacts. However, re-processing of all the seismic
lines has shown that the features are actually real.
When all examples of these features were plotted
(both ‘possible’ and ‘relatively certain’), they were
seen to fall within the central part of the Triassic
Basin, where salt is developed within the Abu
Upper Triassic carbonate build-ups map in the Safawi Block, Jordan. Red line indicates
