The top of the Barrow sandstone in Scalybutt-1 was intersected seven metres above the field wide oil/water contact. Core and log analysis has determined that the upper two metres are of reasonable reservoir quality and contain oil pay, however the reservoir quality of the lower five metres is still to be determined.

The Scalybutt-1 well designed to evaluate the possibility of hydrocarbons to the west of the Woollybutt Oil Field.

A computer simulation model for the field will be constructed on receipt of the final interpreted log and core data. Further, the structural mapping of the seismic data over both the northern and southern lobes will be revised and the depositional model for the sandstone reservoirs updated.

The above work will assist the Joint Venture in determining if the Scalybutt-1 well should be completed as an additional production well (and if so, in which direction) and whether to drill an appraisal well in the southern lobe, west of Woollybutt-3 where a five metre oil column was intersected.

“The results of the Scalybutt-1 well in respect of additional recoverable volumes of oil in the northern lobe and the forward plan will be dependent upon the updated geological model for the area which is expected to be available in around six weeks time,” said Tap Oil.

“The velocity gradient data acquired in Scalybutt-1 enhances the prospectivity of the southern lobe and the drilling of a step-out well is being considered.”
