ABSTRACT:
A casing mandrel for an independent screwed wellhead includes a pin thread adapted for engagement with a box thread of a well stimulation tool lockdown nut for securing the well stimulation tool against the casing mandrel top end. A well stimulation tool and a tubing head spool for use with the casing mandrel are also provided. Safety of well stimulation procedures is thereby improved and well completion time is significantly reduced.
