The company’s Canadian subsidiary Salt Bush Energy is expected to carry out the next phase of the program, beginning flowback and testing, within 48 hours of completing the program on Sunday.
A high-volume, submersible pump will be used to assist with the recovery of frac fluids and to optimise the oil recovery rate.
This is the same practice used by other operators in the area.
More than 1,000 tonnes of proppant placed
The 35-stage frac program at Rex-2 placed more than 1,000 tonnes of proppant into the Rex formation.
Rex-2 is the second horizontal well to be drilled in the multi-well development program for the Wizard Lake oil discovery.
It spudded on July 27 after the Precision Drilling Rig 186 arrived on site the previous day.
Interest increasing to 40%
Whitebark’s working interest in the Wizard Lake oil development will increase from 30% to 40% on tie-in of Rex-2 and 50% following the drilling and completion of Rex 35.
The Wizard Lake oil field was identified using well control and seismic together with geology in 2018 and a development program began with spudding of the horizontal Rex-1 well on November 24, 2018.
An interim production flow rate of 275 bbls oil per day was announced after 10 days clean up.
Production facilities and a pipeline were completed in early June 2019 and Rex-1 began pumping oil on June 5, 2019.
Wizard Lake has a potential field size of 11.2 million boe and up to 20 well locations.
