Spudded on Wednesday, the Riddle-13 well encountered the oil at the top of the Stones River formation directly below the Pencil Cave formation.

“The well could not be drilled any further due to the oil flow and the well was secured as a producer,” Westralian said.

This well was aimed at testing the western area on the lease, which until now has been left unexplored.

Located in a structurally separate block from those previously drilled, this well greatly enhances the lease’s prospectivity.

Before Riddle-13, the company drilled the Riddle-14 well, which has also been confirmed as a future oil production well.

Riddle-14 was designed to test the Sunnybrook and Stones River formations, which are both good oil producers on Westralian’s lease and nearby acreage.
