Calima Energy has declared its first drill campaign in the world-class Montney oil and gas play in Canada an outstanding success on the back of initial test results.
The company – which began first drilling campaign on its 72,000 acre position in British Columbia in January – has advised of successful testing results at Calima-2 and Calima-3 wells.
Our first drilling campaign in this world-class play has been an outstanding success,” Calima’s Managing Director Alan Stein said.
“The three wells provide unequivocal confirmation of the extension of the liquids-rich fairway through the Calima Lands in both the Upper and Middle Montney targets.
“We are extremely proud to have met all our drilling objectives on schedule and without any reportable HSE incidents.
“This has meant, despite the unseasonably warm weather, that the Company now has the necessary data to enable our reserve auditors to complete a new independent reserves and resources statement that should be available in May 2019.”
Continued production testing at Calima-2 resulted in further increases in the rate of liquid recovery.
During the final eight hours of production testing, the well achieved a condensate-gas-ratio (CGR) of 20.06 bbl/mmcf (plant recovery estimate 40.12 bbl/mmcf) with a peak hourly value of 22.15 bbl/mmcf (plant recovery estimate 44.30 bbl/mmcf) through a choke size of 38.1mm.
The measured CGR continued to increase until testing operations were ceased. Calima expects further enhancement to liquids ratios once both wells are brought into production and the water injected during stimulation operations is recovered.
Meanwhile, testing operations of Calima-3 well were halted by an unseasonal early spring melt resulting in the drill site requiring a full decommissioning over a short period of time.
However, Calima noted the well had performed as expected and was flaring gas in the early stage of unloading (recovery of water injected during stimulation) at rates in excess of 2.5mmcf/d.
“These rates are consistent with the early Calima-2 test rates and encouragingly were reached in a shorter period of time,” the company said.
“Management is confident that with additional testing time Calima-3 would have achieved similar maximum flow rates to Calima-2. This is confirmed by preliminary core and log data analysis which give an indication of the productive potential of both wells.
Calima is now undertaking further analysis of core and log data and the Company intends to release further information over the next 14 days.
