Abstract

A blowout preventer (BOP? protector is adapted to support a tubing string in a wellbore so that the tubing string is directly accessible during a well treatment to stimulate production. The BOP protector includes a mandrel having a sealing assembly mounted to its bottom end for pack-off in a casing of a well to be stimulated. The mandrel is connected at its top end to a fracturing head, including a central passage and radial passages in fluid communication with the central passage.
The mandrel is locked in a fixed position by a lockdown nut that prevents upward movement induced by fluid pressures in the wellbore. The advantages are that the BOP protector permits access to the tubing string during well treatment and enables an operator to move the tubing string up and down or run coil tubing into or out of the wellbore without removing the tool. This reduces operation costs, saves time and enables many new procedures that were previously impossible or impractical.
