Dril-Quip details time, cost benefits of vertical subsea tree development
Offshore staff
HOUSTON – Dril-Quip has issued more details on its VXTe vertical subsea tree system which received an OTC 2020 Spotlight on New Technology Award.
The system is designed to eliminate the need for a tubing head spool and for orientations of the tubing hanger, saving time and equipment cost.
Other features include a self-orienting stab sub, automatic space out of the tubing hanger, and an isolated annulus flow with the annulus gate valve packaged inside the tubing hanger. According to the company, this allows operators to run tubing hangers in a similar fashion to casing hangers, but without the need for time-consuming orientation.
Blake DeBerry, Dril-Quip’s president and CEO, added that the VXTe eliminates lead-impression measurement trips, while at the same time giving the option of running the tubing hanger and completing the well during the drilling phase.
“These benefits can eliminate a blowout preventer installation and removal sequence, which is currently a costly step while drilling an offshore well. By streamlining the installation process and avoiding the cost of the tubing head spool and associated parts, the VXTe system can significantly reduce overall project development costs.”
