Abstract
A system includes a tubing head spool (THS) installed in a non-plugged wellbore, the THS having a bore diameter to permit passage of one or more wellbore components corresponding to one or more wellbore components that pass through an associated blowout preventer (BOP). The system also includes an orientation sleeve arranged within the THS and installed, the orientation sleeve being positioned and aligned within the THS via one or more engagement features mating with one or more orientation features within the bore.
Claims20
A wellbore system, comprising:
- a tubing head spool (THS) having a THS bore, the THS bore being a full access bore having a diameter to facilitate passage of one or more wellbore components;
- a blowout preventer (BOP) associated with and upstream of the THS, the BOP being installed after the THS and without plugging a well prior to installation, the BOP having a BOP bore, the BOP bore being a full access bore permitting passing of the one or more wellbore components;
- and
- an orientation sleeve arranged within the THS and installed through the BOP, the orientation sleeve having at least one engagement feature that interacts with at least one orientation feature formed along the THS bore, the at least one orientation feature positioning the orientation sleeve in a predetermined configuration.
