8.6 We have investigated three scenarios. In all scenarios there is a build up of activity in the initial years as the number of drill rigs and fracturing kit increases, with some slowing down at the conclusion of the process as equipment is gradually redeployed to other locations. The lower end scenario sees 190 wells drilled at 20 pads over a period of 6 years. The higher end scenario sees just over 800 wells drilled at 80 pads over a period of 16 years.
