Following on from its successful maiden drilling activity in the Montney basin in British Columbia Canada, Calima Energy is wasting no time to get on with the next stage of production testing, with well stimulation already commenced.
Calima is stimulating both its two horizontal wells, which were spudded in January this year and have delivered outstanding core and wireline log data results.
The wells run for a length of length of approximately 2,500m and stimulation work is being conducted in 92 separate stages.
The 92 sections of the well are almost equally divided, with each section hydraulically isolated from the other stages production in the well bore.
An injection of predominantly water and sand at high pressure is used to fracture the rocks and allow hydrocarbons and formation fluids to flow into the well-bore.
Calima reports that most of the water injected into the reservoir will flow back to the surface and will be collected in storage tanks to be recycled for future use, with the water to be eventually replaced by hydrocarbons.
The stimulation process is tipped to take between 5-6 days for each well, with production testing to commence immediately after.
Commenting on the progress made, Calima Energy Managing Director Alan Stein said:
We continue to be delighted with the operational progress being delivered by the team in Canada and we are excited to be approaching the testing phase of the project which will commence in the next week or so.
“The production tests will be a major milestone for the Company and for the Montney in northeast British Colombia,” he said.
The natural gas produced during well stimulation will be flared while the liquid hydrocarbons will be collected and sold locally, providing Calima with initial remuneration from its wells as well as confidence in securing future commercial production.
The company has a permit to flare approximately 105 mmcf of gas from each well.
The Calima well pad is located in the northern extension of the Montney basin, with the company acquiring 72,000 acres of drilling rights in the region.
