摘要: In a cased wellbore (10) having one or more and cemented drainholes (22, 24) extending therefrom such that the elliptical shaped opening (44) junction of each drainhole with primary well is sealed cut flush inside casing (18), inventive method apparatus are disclosed for: (a) isolating perforated and/or completion within (10), (b) providing flow control means (162, 164) for to permit selective testing, stimulation, production, abandonment, (c) facilitating re-entry into any remedial work.
