Abstract:
Systems and methods for wellbore strengthening are disclosed. An effective way to strengthen a wellbore and prevent future fractures during drilling operations is to induce fractures having a desired fracture width profile and fracture length. Surface back pressure can be used to accurately induce such fractures. The induced fractures which are then sealed can increase fracture gradient of the wellbore thus mitigating future fractures.
