ESD’s Jonny Rutqvist led an investigative team (including ESD’s George
Moridis) in conducting numerical modeling of coupled multiphase
fluid-flow, thermal, and geomechanical processes during gas production
from an oceanic hydrate deposit to study the geomechanical performance
and wellbore stability. The analysis showed that geomechanical responses
around the wellbore are driven by reservoir-wide pressure depletion,
which in turn, depends on production rate and pressure decline at the
wellbore.
