Whitebark Energy Limited (ASX:WBE) has continued with oil production through an extreme cold period as temperatures fell to minus 42˚ Celsius (-55˚C with wind chill) at Wizard Lake Oilfield in the province of Alberta, Canada.
The average temperature range during this time of year is usually between minus 10 to minus 20˚ Celsius.
Mild conditions are forecast for the next seven days with above-average temperatures which will enable normal field operations to re-start.
Good test for new facilities
Managing director David Messina said, “The continued operations of the field during the extremely cold weather was a good early test for our new facilities.
“The health and safety of operators is a key concern during these extreme events, and we were extremely pleased to have no incidents and we can now look forward to increasing the production rates again.”
The production from the field will continue in a manner that will facilitate the well clean-up process and optimise production rates and uptime for the long term.
As with other nearby fields producing from similar reservoirs, the present three wells of the Wizard Lake Oilfield are expected to require up to 90 days to attain their maximum flow rates.
New facilities and pipelines commissioned
The company recently commissioned new facilities and pipelines at Wizard Lake which separate the gas from the liquids for sale through the Petrus gas processing facilities.
Gas throughput has been held at 2 – 2.5 mmcfd (million cubic feet per day) while the wells continue to clean-up and stabilise.
Well operations have also focused on re-establishing full flow from the wells.
The Wizard Lake Oilfield was identified using geological information obtained from wells drilled mainly in the 1950s and has the potential to contain more than 24 wells targeting 11mmboe.
An upgrade to production facilities was commenced in November 2019 and included a 3-kilometre gas pipeline to connect to local gas networks to ensure high gas and oil production rates can be managed.
These facilities were completed in late December 2019 and production began.
Following the close of Stage-1 of the Wizard Lake acquisition, White Bark now owns a 60% working interest in the field.
After the completion of Stage-2, the company will own 100% in the field and 90% in the Rex 1 and Rex 2 wells.
Once Stage 3 closes in December 2020, Whitebark will own 100% of all assets in the Wizard Lake field.
