A conceptually new completion method involving forming of lengthy drain channels to establish connectivity with the productive formation is considered. A new type of rotary perforator allows non-damaging drilling of drain channels up to 1 m long and 20 mm in diameter. The paper presents results of the detailed analysis of the completion technology, as well as conclusions and practical recommendations.
Key words: drain channels, rotary perforator, productive formation, completion technology.
