Another thing to take into account is the TVD of the wellbores. As MK-2ST1 is vertical it has drilled deeper on a TVD basis related to MK-2 for comparable measured depths.... Based upon my calcs they likely drilled past the interval where they did the first MDT attempt in MK-2. So, it is strange that if this was the priority target in the first wellbore, why not targeted in the sidetrack. But on a lateral displacement at that interval the wellbores were about 200m apart, so this probably shows the variability of the reservoirs. Each of the sidetracks will provide some useful information when comparing data with the primary wellbore.
