WP3 - Numerical modelling of FOC data
WP3 addresses the challenge of differentiating coupling effects of different energy sources from the well interior, well exterior, and the well itself and quantify the behaviour of each component for real-time assessment of well and seal integrity using FOC data.
WP3 starts with performing thermo-hydro-mechanical (THM) modelling and seismic wave modelling to quantify the coupled behaviour and micro-seismicity in the near-well region. The initial modelling (e.g., stress path) and sensitivity assessment will also feed into WP1 to design the laboratory test for material models.
With information from WPs 1 and 2, WP3 numerically predicts the FOC data along the well for different injection stages to identify the failure mechanism and FOC signatures or patterns. Reduced order modelling techniques will be applied to accelerate computation when analysing and interpreting data.
With the modelled FOC data and failure modes, the final goal of WP3 is to develop an inversion model (or back calculation, history matching) that provides quantitative integrity monitoring of in-situ behaviours based on DSS, DTS, and DAS data.
Four tasks are defined in WP3:
- Task 3.1 Numerical modelling for near-well geomechanics and seismic wave
- Task 3.2 Prediction of FOC data along well
- Task 3.3 Reduced-order modelling
- Task 3.4 Inversion of FOC data
