Abstract

A well insert for insertion into a foundation of a well is provided. The insert comprises a channel therethrough for the well; and the well insert is arranged so that when the well insert is inserted into the foundation of the well, the channel of the insert can be adjusted relative to vertical. A well assembly comprising the well insert and a well foundation is also provided as is a method of inserting a well insert and a method of controlling the orientation of a well using a well insert.

First claim

1 . A method of controlling the orientation of a well, the method comprising:
installing a well foundation, the foundation having a channel therethrough; measuring the angle of the foundation relative to vertical; providing a well insert, the well insert comprising a channel therethrough for a well; and inserting the well insert into a channel in the installed well foundation, wherein the well insert corrects for a misalignment of the channel in the well foundation from vertical after the foundation has been installed.

2 . A method according to claim 1 , wherein the method comprises determining the offset between the channel of the well foundation and vertical.

3 . A method according to claim 1 , wherein based on the measurement of the angle of the foundation relative to vertical it is determined what is the appropriate angle between the channel of the insert and an outer surface of the insert.

4 . A method according to claim 1 , wherein the method comprises:
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 inset into the channel in the installed well foundation.

5 . A method according to claim 4 , wherein the well inserts of the plurality of well inserts each have angle between the channel of the insert and the outer surface of the insert that differs by at least 0.5 degrees from the other well inserts of the plurality of well inserts.

6 . A method according to claim 1 , wherein once the desired angle of the channel relative to the engagement surface is determined, the method comprises making an appropriate well insert.

7 . A method according to claim 1 , wherein the angle of the channel of the well insert relative to the channel of the well foundation is adjusted based on the measured angle of the foundation.

8 . A method according to claim 1 , wherein whilst installing the well foundation the orientation of the foundation is not controlled

9 . A method according to claim 1 , wherein if it is determined that there is no offset between the channel of the well foundation and vertical, the method comprises providing and inserting a well insert which has a channel that is parallel to the channel of the well foundation.
