Guess what I've just heard/read?

Sometimes you’re on a job subsea, and you hear something that is hard to believe.
Is it true? They can’t do that, it’s crazy! True? Rumour? Who Cares?
Post a new message in this section and let us know about it.

Subsea dual bore trees have a production and annulus bore passing vertically through the tree body with production and annulus master valves and swab valves oriented vertically in the main block of the tree.

They are designed to allow vertical access to the main production bore and to the annulus bore during installation and workover operations.  When a dual bore subsea Christmas tree is connected to a subsea wellhead it must interface with the tubing hanger previously installed in the wellhead.

Subsea dual bore trees are often referred to as vertical tree and most recommended for gas wells with less intervention operations. Great stuff!
