Digital twin cuts kick-detection time by 62% on North Sea HPHT well
A live hydraulics twin paired with managed pressure drilling flagged a 3.5 bbl influx in under 40 seconds — well below the 90-second industry benchmark.
By Dr. Henrik Solberg, Well Engineering Lead
On a recent high-pressure high-temperature (HPHT) exploration well in the Central North Sea, Macpex's real-time hydraulics twin — coupled with a managed pressure drilling (MPD) choke manifold — detected a formation influx of 3.5 bbl in 38 seconds.
Why it matters
Industry surveys put average kick-detection time on conventional systems between 90 and 180 seconds. Every second shaved reduces influx volume, shortens the circulation-out phase and lowers the probability of escalating to a well-control event.
How the twin works
The twin ingests standpipe pressure, flow-in, flow-out (Coriolis), pit volume and downhole ECD from an along-string measurement sub. A physics-based model runs at 5 Hz and cross-checks the measured versus expected annular return. Divergence beyond a tuned threshold triggers an amber alert on the driller's screen and an SMS to the on-tour engineer.
Next steps
The system is now being rolled out to two further HPHT campaigns in Q3 2026, with automated choke response — currently advisory only — targeted for field trial in early 2027.
