摘要：
A wellhead is formed by extruding a plurality of tubular liners off of a mandrel into contact with an outer casing. The first tubular liner and mandrel are positioned within the wellbore with the tubular liner in an overlapping relationship with the outer casing. At least a portion of the tubular liner is extruded off of the mandrel into contact with the interior surface of the outer casing. The first tubular liner is extruded off of the mandrel by pressurizing an interior portion of the first tubular liner. Subsequent tubular liners are positioned in concentric overlapping relation and similarly extruded off of a mandrel into at least partial contact with the interior surface of the outer casing.
