Abstract
A tubing head spool for use with a BOP
protector in fracturing or stimulation treatments is described. The tubing head spool includes a reinforced area of its sidewall that is adjacent a bottom flange of the spool and surrounds a supports an annular seal which provides a sealing engagement between the end of the BOP
protector and a secondary seal in a bottom of the spool.
The reinforced area contains radial pressure transferred through the annular seal during well stimulation treatments. The reinforced area has a pressure rating greater than the pressure rating of the remainder of the tubing head spool so that the modified tubing head spool is adapted for use with the BOP protector for high pressure well stimulation treatments. The advantage is an economic tubing head spool that enables safe high pressure well treatments at pressures up to the pressure rating of the reinforced area of the tubing head spool.
