High-pressure, high-temperature (HPHT) wells demand early, confident decision-making—yet traditional analysis timelines can delay critical rig strategy choices.

This case study shows how Aquaterra Energy’s Riser Analysis Lite (RAL) service delivered rapid results, providing the technical assurance needed to move forward with a lower-cost drilling approach, previously explored by Martin Harrop, Offshore Analysis Manager, and Annie Constable‑Berry, Senior Offshore Analyst, in our Tech Talk: From Assumption to Assurance in Two Weeks.

By assessing riser performance, fatigue life, and environmental loading, the study enabled the operator to confidently move away from a semi-submersible solution and adopt a jack-up strategy—without compromising safety or performance.

  • Early-stage riser analysis supported faster, better-informed rig selection decisions
  • A jack-up drilling strategy was technically validated for HPHT North Sea conditions
  • Up to $45 million cost savings per well were unlocked through optimised rig selection
  • Preliminary analysis was delivered in as little as half a week, accelerating project timelines
  • System performance was confirmed under extreme conditions, including 100-year storm events
