چکیده انگلیسی
Results of the coupled model indicate continued integrity of the caprock for the case study project for the current operational program for almost all the considered case scenarios, except for an extreme case. Therefore, higher injection pressures than the current pressure were investigated to assess the MOP. Results indicate that the MOP was highly sensitive to the fracture density, direction, and height. Results also display a minor impact for the horizontal fractures on the MOP for the case study while fractures with the dip angle between 25° and 65° show a significant impact on the caprock integrity, hence, the MOP. Moreover, results indicate an overestimation of the MOP by up to 23% when neglecting the NFs. Comparing the results of different case scenarios with those of conventional isotropic models highlights the requirement to include the effect of NFs in caprock integrity studies.
