Lateral leakages are related to the fault throw. The connectivity of the permeable layers at both sides of the fault was used as criterion to diagnose the risk of lateral leakage. Four vertical permeable layers—specifically C 2 hl, P 1 q, P 1 m, and P 2 ch—were identified in the XGS structure based on well drilling and the development history.
