Tamaska participated in the drilling of the West Klondike discovery well in late 2012. The well commenced producing gas from the lower Nod Blan on 4 September 2014. The lower gas zones were depleted and the remaining unproduced zone is the Lario oil sand.
During the FY17 year Oleum Operating LLC purchased an interest of 76.7%, and assumed Operatorship. Oleum focussed on the oil zone in the Lario, re-entering and recompleting the well before performing a small hydraulic frac. Initial workover results were encouraging with over 100bopd in short term testing. Following the work over Oleum installed a jet pump on location to assist with oil lift. The well was placed back on production on 17 April 2017.
In July 2018, the Operator ran a pressure survey on the well and the reservoir appears to be close to initial pressure, indicating the flow into the well is constrained, potentially due to frac sand over the completion. The Operator is currently assessing plans to treat the well and improve production.
The field is potentially large enough for another production well, but the decision to drill is contingent on improved production performance from the Lario.
