Ensuring injection operations for pressure maintenance or waste disposal remain within the target injection domain has important implications: economically by providing better sweep efficiency leading to less injectors, operationally through the ability to inject safely, and reducing environmental impact providing support on license to operate. Injection geomechanics provides insights into injector performance and injectivity, which depends on effective stress affecting rock deformations and fluid flows around the wellbore region and in the reservoir. This helps us improve completion design, predict fracture extension over time, prevent injector failures, and deliver safer operating guidelines for fluid containment. Methods to ensure containment, surveillance to track and verify containment as well as cases where containment is/was challenging, will be presented.
