Influence of low-amplitude tectonic faults on the effective development of multizone fields of Western Siberia

Authors: A.S. Chinarov, R.A. Rybakov, O.A. Stepanova (Gazpromneft NTC LLC, RF, Saint-Petersburg)

Key words: reservoir, fracturing, strike-slip faults, well productivity, well efficiency.

The strike-slip faults at the bottom of the sedimentary cover have a great influence on the higher reservoirs of the cross-section and where a porous reservoir is expected, there can be a porous-fractured reservoir. In some cases, benches meet vertical nonuniformity that’s appeared at the lower Jurassic and has tectonically conditioned genesis. These zones are a complex of small faults and they can’t be recorded definitely with the help of standard seismic methods, but they have a great influence on the well work.
