Method and system for well and reservoir management in open hole completions as well as method and system for producing crude oil

摘要

According to the method for well and reservoir management in open hole completions, a data acquisition module (100) is advanced through the wellbore and acquires data providing information revealing fractures in the wall of the wellbore, and at least one blocking system (1002, 3000), on the basis of the data acquired, is placed in the wellbore(199, 2199, 3006) at the location of a fracture in the wall. The data acquisition module (100) is advanced by interaction with a fluid present in the wellbore, and the data acquisition module acquires data providing information on its own position in relation to the wall (3005) of the wellbore (199, 2199, 3006) and is controlled on the basis of said data in order to maintain a distance to the wall of the wellbore during its advancement. A system for well and reservoir management in open hole completions is further disclosed.
