It hopes the first of the new wells will be under way by the end of 2015.
Matthew Idiens, chief executive, said: "The results to date from the Mancos Shale core analysis are in line with our expectations and re-emphasise the prospectivity of this exciting opportunity.
"Our detailed geological and engineering assessment suggests that targeting the Mancos in the Cisco Dome field will deliver the best results going forward for our shareholders and, given that we would need to re-permit a horizontal well at the State 1-34 location, we plan to target the new location with better well control and excellent surface infrastructure with the gathering system and processing plant nearby.”
Rose said last month that it had halted State 1-34’s attempts to tap into deeper conventional resources.
Today it added that it can no longer use the 1-34 vertical well for the horizontal leg as it would be required to permit a whole new location stepping away and drilling laterally towards the existing well location.
Now that it has data for the Cisco Dome field, Rose believes that the proposed well location in that area has much stronger success potential.
Core analysis from 1-34 will be combined with log data and mud log data for a comprehensive analysis of the Mancos.
Rose added that it had been made progress on the permits for the six new wells with no red flags from the internal site evaluations.
