Technology of perforating allows forming lengthy drain channels in the near-wellbore region

Authors: D.A. Berdnikov, I.V. L’vova (TatNIPIneft, Bugulma, Russian Federation), N.I. Rylov, L.M. Mironova (Nauka OOO, Bugulma, Russian Federation), L.B. Khuzina (Almetyevsk State Petroleum Institute, Almetyevsk, Russian Federation)

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.
