Calima readies another well for February fracking

Perth-based Calima Energy is setting itself up for a busy February after completing the drilling of the final Pisces well within budget at its Brooks project in Alberta, Canada.

A fracking crew is due on-site next month for a proposed multi-stage fracture stimulation and testing program across all three recently drilled Pisces wells as the company seeks to show that it can drill wells at will that regularly show acceptable returns.

Pointing to the efficiency of its drilling operations, Calima said Pisces 3, the third well targeting the Glauconitic formation, was spudded on the 2nd of January and drilled to a measured depth of about2,600 metres in seven days. The Glauconitic zone is a shallower, or younger target compared to Calima’s core Sunburst formation.

Pisces 1 and 2 were drilled in December and Calima said their multi-stage fracture stimulations were recently completed. They are presently being tied-in to existing infrastructure and facilities and the wells currently sit in their seven-day shut-in period prior to opening the frac ports and running pumping equipment.

The company said the Pisces 1 and 2 fracs have 10 – 15 tonnes of sand per stage in comparison to the Pisces 3 fracs which will be using 30 - 40 tonnes of sand per stage. Final modelling of the frac program is underway to fine tune and optimize the program based on reservoir thickness and quality.

After pumping each frac stage, a multi-cycle sliding sleeve is closed to allow the newly initiated fractures to “heal” around the frac sand proppant. Calima said this is a mitigating factor to ensure that the frac sand stays in the formation which minimises the need for future frac sand cleanouts, whilst increasing the general effectiveness of the process.

After the seven-day shut-in period, the multi-cycle sliding sleeve frac ports are opened, pumping equipment is installed and the well will begin the flow back period. Given that large amounts of frac fluids are being used, Calima estimates it will take between 30 and 45 days to recover sufficient frac fluid to determine reliable oil and gas flow rates from the Glauconitic Formation.

Full flow rates from the first two Pisces wells are expected late February or early March. Calima said Glauconitic wells are expected to have initial production rates of between 200 and 400 barrels of oil per day.

The Company has finished drilling its 3-well Pisces Brooks Alberta program. We are very pleased with the efficiency and expediency that the Calima Operations Team executed on this program.

The drill costs to date are on budget. The rig has been released from Pisces 3, and we are now preparing for the multi-stage frack of 3 in February 2022.

Calima’s March quarterly will no doubt be an interesting read as flow rates from the fracking program across all three Pisces wells are reported.
