Digital Twins for Offshore Assets: Enabling Safe CCS in Depleted Subsea Reservoirs and Full Electrification of Subsea Production Systems

By Oko Immanuel, M.Eng – Founder, Offshore Pipeline InsightMarch 18, 2026 The energy transition is accelerating in 2026, and depleted subsea reservoirs are no longer “end-of-life” assets—they’re the next frontier for Carbon Capture and Storage (CCS). At the same time, operators are racing toward electrification of subsea production systems to slash emissions and OPEX. The common thread powering both? Digital […]

Ideas Using CFD to Predict Thermal Expansion in HPHT Subsea Wellheads

By Oko Immanuel, M.Eng – Founder, Offshore Pipeline InsightMarch 17, 2026 High-Pressure High-Temperature (HPHT) subsea wells push equipment to extremes: reservoir temperatures often exceed 150–200°C, pressures hit 15,000+ psi, and cold seawater (~4°C) creates massive thermal gradients. One of the biggest integrity risks? Thermal expansion—not just in pipelines, but right at the wellhead.Trapped fluids in annuli, […]

Landmark, Compass, and Petrel in Subsea Modeling: CFD for Wellbore and FEA for Subsea Connectors

By OkoFounder, Offshore Pipeline InsightMarch 16, 2026 In the evolving landscape of offshore oil and gas engineering, subsea modeling plays a pivotal role in optimizing designs, ensuring safety, and enhancing operational efficiency. Halliburton’s Landmark suite, including Compass for well trajectory planning, and Schlumberger’s Petrel for subsurface reservoir modeling, provide powerful platforms for integrating advanced simulation techniques like Computational Fluid Dynamics (CFD) […]
