Overview
The CAPEX and schedule risk associated with subsea construction work can make riser gas lift economically unattractive for marginal or maturing fields.
Why It Happens
Conventional riser gas lift retrofits require subsea welding or mechanical connection at depth, specialist vessels, and long lead times for bespoke equipment. For many brownfield fields, this CAPEX threshold means the benefit of gas lift — improved liquid offtake, reduced slugging, lower wellhead backpressure — is never realised despite being technically justified.
How It Can Be Fixed
Use Paradigm’s Flexi-Coil® in-riser gas lift downline service. Flexi-Coil® is deployed from the platform into the riser without any subsea intervention, delivering gas injection directly to the target depth. This platform-based approach eliminates the need for subsea construction work and has demonstrated CAPEX savings of up to 80% compared with conventional riser gas lift installation methods.
Why Paradigm
Paradigm’s Flexi-Coil® downline service is specifically designed to provide in-riser gas lift and flow stabilisation without DSV or rig involvement. It can be deployed from an FPSO or fixed platform, navigates complex riser geometry, and reaches depths up to 15,000 feet. The 80% CAPEX saving claim is based on Paradigm’s documented operational experience, making it a compelling option for fields where conventional gas lift has been deferred due to cost.
