Following the first phase of the Dubhe-1 well programme, Pantheon Resources has successfully drilled, logged and cored the Dubhe-1 pilot hole to a total measured depth of 12,833 ft, equivalent to 8,699 ft true vertical depth.
A deviated pilot hole had to be tackled to gather cores and logs to select the optimum landing zone for a subsequent lateral sidetrack in the primary SMD-B zone. The well successfully reached the planned true vertical depth and achieved all planned target reservoir penetrations -- both primary and exploration objectives.
The primary target of Dubhe-1 was the topset horizon (SMD-B), appraising the already discovered resource. Additionally, the well was designed to encounter three further exploration horizons (Prince Creek, SMD-C and the Slope Fan System), none of which have previously had any resource estimate attributed to them. Logs confirm additional prospective resource upside in these horizons.
Post analysis of the thickness and quality of the primary target topset, the company has confirmed that the SMD-B has exceeded the upside pre-drill expectations. The gross thickness of the hydrocarbon column in this interval was measured at 565 ft true vertical thickness; exceeding pre-drill expectations by 26%.
Following this, the company plans to drill, and subsequently flow test the planned sidetrack lateral in the SMD-B horizon to refine the production well type curve.
Dubhe-1 has confirmed a gross 565 ft TVT hydrocarbon bearing column in the SMD-B primary target horizon. The hydrocarbon mix between oil, NGLs and gas will be determined after flow testing.
Erich Krumanocker, chief development officer, said, "We are delighted to announce the Dubhe-1 pilot hole results as a success. The well confirms the presence and quality of the oil and gas reservoirs in the Ahpun field, exceeding our pre-drill expectations. We are now transitioning toward field development planning in support of capital efficient commercial production. The upside presented by the SMD-C and Slope Fan zones highlights the enormous potential in our portfolio."
