Technical Examples

A method of extending an insulated wire through a wellhead opening of a well that includes casing having a top. The method makes use of an annular cap sized to engage and be retained by the top of the casing, the annular cap having smooth top and radially inward surfaces and defining an aperture. The annular cap is placed onto the top of the casing and the insulated wire is passed through the aperture, wherein should the insulated wire touch the annular cap the insulated wire will remain undamaged by the smooth top and radially inward surfaces.
