A second 4 1/2-in. Torus insert safety valve design is now qualified to enhance production from mature fields.
It follows availability of existing 2 7/8-in. versions.
Torus improves on basic flapper type safety valve design. It allows for a central conduit to pass through the core where the conduit may be hydraulic (mini-coil or capillary string), electrical, or fiber optic, reports the manufacturer. This allows for installation of artificial lift or downhole monitoring of existing wells without requirement of full, costly workovers.
New 4 1/2-in. torus achieved API 14A. It may be employed in such typical applications as liquid loading, chemical stimulation to prevent scale buildup, corrosion inhibitors injection, downhole monitoring, and insert gas lift.
It has also completed further testing to allow a rotational umbilical to be installed through it. This enables progressing cavity pumps to be installed in offshore and safety valve applications.
Additional insert safety valve particulars are available free upon request.
