Well Construction
Casing & Tubing Running Services
Professional casing and tubing running services with precision torque management and full well integrity assurance on every string — ensuring your wells are built to last.
Service Overview
Precision Casing & Tubing Running
Proper casing and tubing installation is critical to long-term well integrity. Sequential International provides professional casing and tubing running services with calibrated torque turn monitoring, centraliser placement, and float equipment verification — ensuring every string is correctly installed.
Our casing crews work alongside drilling contractors across Niger Delta development wells, delivering efficient, high-quality string running operations that meet operator and regulatory standards.
“A poorly run casing string is a well integrity risk that can last the life of the well — we get it right the first time, every time.”
