Central Petroleum encounters continuous oil shows in Surprise-1

Central Petroleum (ASX:CTP) finished the year on a high encountering continuous oil shows in sandstone while drilling the Surprise-1 Re-entry H well. 

The company reported on several trips oil has collected in the possum belly and over the shakers and continuous “breakouts” of oil droplets are apparent in the lightweight brine mud system.

Visual observation of oil in the drilling fluid in the possum belly and over the shakers indicates that the quantity is increasing on circulation to the surface following connections.

Central said that as the oil is floating on the surface of the drilling fluid and dispersed in droplets throughout, no quantification of oil volumes can be given

At last report Surprise was drilling ahead horizontally at approximately 10 metres/hour at a Measured Depth of 2,630m and a True  Vertical Depth (TVD) of 2,543 metres.

Approximately 75 metres of horizontal well bore has been drilled.

On the most recent trip back in to the well to a TVD of 2,542 metres, trip gas with a peak reading of 1,000 units was also recorded.  Connection gas was reported to have increased to 200 units over a background of approximately 80 units with a similar composition to the trip gas.
