Minimizing leakage and excess pressure buildup
The storage capacity of the Bjarmeland formation is assessed by obtaining optimized injection strategies while penalizing leakage and pressure buildup. This example demonstrates that pressure is an important aspect when designing injection strategies. Managing pressure buildup in the formation can be carried out through appropriate well placement as well as water production. More details of the following examples can be found in .
