Eni developed automated workflows linking Schlumberger ECLIPSE flow simulation with Abaqus finite element analysis to create full-scale geomechanical models. The approach converts pore pressure data into stress-strain simulations that forecast compaction, well integrity risks, and environmental subsidence over multi-year production periods. Implementation reduced model build time from eight weeks to four weeks and enabled larger models with millions of degrees of freedom.

Key takeaways

Coupled flow and geomechanical simulation improves subsidence prediction accuracy versus homogeneous models

Automated data transfer from ECLIPSE to Abaqus cut model creation time by 50 percent

FEA enables realistic treatment of non-homogeneous rock properties and elasto-plastic behavior

Parallel processing supports full-field models with millions of degrees of freedom

Predictive models support regulatory compliance and sustainable field development planning
