Dual Casing Guide

Engineered Precision for Dual String Well Construction

PDG, in collaboration with Red Kite Oilfield Services, brings the Dual Casing Guide — a patented, field-proven solution designed to simplify and strengthen dual string installations within conductor casing.

Developed in partnership with leading wellhead manufacturers, the Dual Casing Guide provides a contoured, precision-machined structure that accurately guides two surface casing strings in parallel within the conductor casing, maintaining perfect side-by-side spacing from surface to setting depth.

Key Benefits

Doubles wellbore slot capacity — enabling more wells per conductor, reducing surface footprint, and increasing platform productivity.
Maximises cement flow area — tapered upper and lower profiles improve circulation and cement placement for reliable zonal isolation.
Streamlined installation — simple rig-up using dual slips, spiders, and elevators; guides are run on a tubular string and positioned without casing attachment.
Compatible with industry wellhead systems — includes adjustable seal subs and split bowls for precise height alignment and sealing integrity.
Proven design pedigree — backed by Patent No. 6,012,529, ensuring unique geometry and verified performance in offshore and land applications.

Designed for Efficiency and Safety

The Dual Casing Guide was developed to minimise rig time, enhance structural accuracy, and improve cementing efficiency. With tapered entry surfaces, optimized spacing, and robust materials, the guide ensures smooth casing deployment — even in challenging well geometries.
