Magister Scientiae - MSc (Earth Science) / The Orange basin is relatively underexplored with 1 well per every 4000km2 with only the
Ububhesi gas field discovery. Block 1 is largely underexplored with only 3 wells drilled in the
entire block and only well A?F1 inside the 1500km2 3?D seismic data cube, acquired in 2009.
This study is a reservoir characterization of well A?F1, utilising the acquired 3?D seismic data
and re?analysing and up scaling the well logs to create a static model to display
petrophysical properties essential for reservoir characterization.
For horizon 14Ht1, four reservoir zones were identified, petro?physically characterized and
modelled using the up scaled logs. The overall reservoir displayed average volume of shale
at 24%, good porosity values between 9.8% to 15.3% and permeability between 2.3mD to
9.5mD. However, high water saturation overall which exceeds 50% as per the water
saturation model, results in water saturated sandstones with minor hydrocarbon shows and
an uneconomical reservoir.
