Casing is currently being run across the hydrocarbon zones prior to suspending the Mawar-1 well.
Mawar-1 has reached its total depth of 1,292m and wireline logging, pressure and fluid sampling has now been completed.
Preliminary analysis of these data indicate that the well encountered gas in the primary objective (Ridan Sandstone) and preliminary log analysis suggests Mawar-1 has encountered up to 25m of Ridan reservoir at a depth of 1,005m.
The presence of gas in this interval is indicated by pressure analysis and sampling.
A deeper secondary objective (Rampayoh Series) also has good hydrocarbon indications in cuttings and sidewall cores in an inter-bedded sand-shale sequence.
Fluid samples have been taken from two depths within this zone.
The samples remain sealed for laboratory analysis but indications are that they contain oil.
Reservoir quality in the upper part of the Rampayoh Series is unclear and will only be confirmed with further analysis of the well data.
The Mawar-1 well will be suspended and the rig will move to the nearby Markisa-1 location which will test the oil potential of a younger reservoir in a separate fault compartment of the Belait Anticline.
