Likely the most common source of geomechanical changes in the subsurface are a product of the change in effective stresses. Majority of subsurface practitioners in the industry acknowledge that these changes are driven by changes in formation pressures, and in the unpredictable changes of rock fabric that have occurred in the surrounding SRV of an existing hydraulic fractured well. Whether due to production, and associated pressure decline the effective stress changes often drive geomechanical behavior during oilfield operations. This includes effects during injection operations like: creation of microseisms events, fracture asymmetry, as well as during production operations (such as parent-child effects). This session is intended to highlight these issues as well as discuss potential mitigating efforts.

This session focuses on incorporating geomechanics into unconventional reservoir development for reducing drilling and completion risks. We will discuss integrating geomechanics into the workflow and using geomechanics to optimize reservoir development. We will also consider geomechanics risks and mitigation strategies, including pore pressure prediction and wellbore stability techniques.

Changes in effective stresses from depletion or injection can have significant impacts on the behavior of the reservoir. Risks associated with compaction, hysteresis, stress path, leakage, fault reactivation, formation breakdown, induced seismicity, and well interference are just a few of the potential consequences of changes in effective stress during production or injection. This session will focus on geomechanical analysis, modeling, monitoring, mitigation, and risk analysis of the dynamic changes to the reservoir as a function of the change in effective stress.

The state of stress is a key factor in well performance but many geomechanical workflows stop at characterization or simulation.  This session will examine how we can extend these key factors of stress into downstream workflows and capital deployment decisions using advanced applications of big data, AI, and large compute, enabling the exploitation of challenging acreage positions and new business development strategies.
