Varying Access Points for Tubing and Casing Monitoring and Casing Annulus Remediation Systems

A method for connecting a casing annulus remediation system to a wellhead with a longitudinal axis, a lateral port which is substantially perpendicular to the axis, and at least one string of casing supported in the wellhead and extending past the lateral port into the well, defining an annulus, the method comprising:

• (a) providing an adapter with a body having first and second ends, the first end having a planar surface, the second end having a planar surface positioned at an angle greater than 0 degrees and up to 90 degrees relative to the first end;
• (b) sealing the annulus from the atmosphere by inserting a plug into the lateral port;
• (c) connecting the first end of the adapter to the wellhead such that the planar surface of the first end substantially covers the lateral port and the plug;
• (d) connecting a valve to the planar surface on the second end of the adapter body;
• (e) after the valve is connected, removing the plug;
• and
• (f) connecting the remainder of the casing annulus remediation system to the valve.
