Delta can provide customers with several sizes of Dual Block X-Mas Trees
having manual operated valves and actuator operated valves.
The purposes of using Dual Bores is producing oil from different levels inside
the same well and using it for multi-lateral drillings.
Delta valves can be integrated into tree blocks using API 6A standards.
The associated tubing hanger sealing systems are designed accordingly to
provide an overall integrated design installation.
With the most modern CAD design facilities (Solidworks/FEA), Delta can
quickly produce a design for a desired integral tree block configuration. This
is manufactured to the same high standards and generally from the same
materials as Delta valves and can incorporate. Delta’s hydraulically operated,
wireline-cutting-and-sealing valves as indicated opposite. These valves are
designed to fail-safe in an emergency and to cut braided a slickline wire. A
variety of proprietary actuators can be offered for this duty.
For services where higher corrosion levels may be experienced and/or H2S
embrittlement may be expected, integral tree blocks provide an economic
solution by means of Inconel cladding of bores, sealing areas and valves
cavities. To the left is a typical assembly drawing for a Delta dual block tree
with the following specifications:
