... leakoff coefficient and the time that the fracture begins to close. From the closure stress, the minimum horizontal stress can be estimated (Castillo, 1987). However, the field data shows the pressure versus G-function time is always not linear, which is commonly contributed many nonideal behaviors...

Although the overlying caprock is of the order of 80 m thick, penetration of the fracture into the overlying caprock is considered undesirable. Unfortunately, the uncertainty ranges on the minimum horizontal stress for Reservoir 1 and its...

... on casing integrity. Our simulation results indicate that cement deficiency could intensify the load nonuniformity around the borehole which escalates the potential threats for casing failure. When cement deficiency reaches 45° along the minimum horizontal stress, it has the largest influence on the stress...
