The well intersected a continuous reservoir section from the casing shoe at 1,572 metres measured depth (MD) to the true depth (TD) of the well at 3,033 metres, with a high quality reservoir accompanied by excellent oil shows (fluorescence and cut) and elevated gas readings.
Increased oil production rates
Whitebark Energy managing director David Messina said the company was pleased with its Rex-2 progress and with the broader success of the drill program in the Rex play.
He said: “We are looking forward to a successful fracture stimulation program followed by significantly increased oil production rates due to the better-quality reservoir we have seen while drilling Rex 2.”
Completion anticipated within 7 days
Due to the reservoir’s continuous nature in the horizontal section, the frac stages have been evenly spaced along the well bore at about 41 metres.
Each stage will emplace about 35 tonnes of proppant, using a crossed linked gel to achieve high proppant concentrations at low pump rates.
Frac work is expected to be complete within seven days and will be followed by normal clean-up flows.
Production rates exceed initial estimates
Whitebark’s development program at Wizard Lake, an oil field potentially hosting more than 20 wells, began with the spudding of the horizontal Rex-1 well on November 24 last year.
Initial flow testing of Rex-1 recorded rates of more than 300 barrels of oil per day and the total oil produced from a 16-day flow test was 2,845 barrels – a 55% increase on initial estimates.
An interim production flow rate of 275 barrels of oil a day was set after ten days clean up and production facilities including a pipeline were completed in June this year, with Rex-1 beginning to pump fluids on June 5, 2019.
