PRESS RELEASE - TCO has announced the successful installation of the first API 19CI qualified retrievable injection valve on the Norwegian Continental Shelf (NCS).

First API 19CI qualified retrievable injection valve successfully installed on the NCS

TCO, one of the energy industry’s leading suppliers within advanced downhole chemical injection systems, today announced the successful development and installation of the API 19CI Qualified FNR (Fall through protection, Non-return, Retrievable) injection valve.

The installation, for a major Norwegian Operator, is the first API 19CI qualified retrievable injection valve to be successfully installed on the NCS.

The API 19CI specification, which was released in 2019, states the requirements for chemical injection devices intended for use in the worldwide petroleum and natural gas industry.     

This includes requirements for specifying, selecting, design verification, validation testing, manufacturing, quality control, testing, and preparation for shipping of chemical injection devices.

The FNR injection valve allows operators to retrieve and change the valve or Anti-U-Tube mechanism during the well’s lifetime, which can save operators the potential costs of recompleting a well due to CIV failure.

The FNR injection valve has a pressure rating of 10000 psi and can operate at temperatures up to 150 degrees Celsius, making it suitable for various applications.

The technology is based on the already proven permanent CIV from TCO and the back pressure retention mechanism was redesigned to meet the requirement of 5000 psi Anti-U-Tube prevention.

TCO developed the FNR injection valve with support from SLB (Schlumberger Limited), who supplied mandrel and running tools in the API test and field trial. This enabled TCO to increase the side pocket mandrel offering, to meet the enhanced criteria.

Talking of the development project and outcome, Henriette Bringsvor, Vice President Global Sales at TCO, said: “We recognize that by working with leading technology providers, we can ensure that we can deliver the best possible solution for our customers.

“This development has set a new standard for injection valves. The FNR injection valve provides flexibility, safety, and reliability, allowing operators to improve efficiency in their operations which in turn reduces costs.

 “We believe this new ground-breaking tool will drive further advancements which will ultimately benefit both operators and the industry as a whole in the years to come.”
