How far can well point locations move before an amendment is required?

A well permit amendment is required when there is a change to the surface wellhead coordinates that results in a change to the legal surface location (NTS or DLS coordinates).  For example, if the well is located in a boundary and a proposed change causes the legal surface location to change from 1-3 to 3-3. An amendment is not required when changing the wellhead location if there is no change to the wellhead surface location (NTS or DLS coordinates).  However, if the wellhead location changes where an amendment is not required, the new well center coordinates must be submitted through eSubmission in the Drilling Section, Summary Report. The permitted well coordinates can then be changed to the new wellhead location.
