Well insert
A method of controlling the orientation of a well 8 comprises installing a well foundation 4 having a channel 10 therethrough; measuring the angle of the foundation relative to vertical; providing a well insert 2 having a channel 6 therethrough for the well; inserting the well insert into the channel in the installed well foundation; and wherein the well insert corrects for a misalignment of the channel in the well foundation from vertical after the foundation has been installed. The method may comprise providing a plurality of well inserts, wherein each of the well inserts has a different angle between channel of the insert and the outer surface of the insert; and wherein the method comprises selecting an appropriate well insert from the plurality of well inserts and inserting the selected well insert into the channel in the installed well foundation. An appropriate well insert is made once the desired angle of the channel of the insert relative to the outer surface of the insert is determined. The angle of the channel of the well insert relative to the channel of the well foundation may be adjusted based on the measured angle of the foundation.
