Long-term bottom-hole production monitoring efficiency in case of commingled production by down-hole equipment on Priobskoye oilfield

Authors: A.V. Baryshnikov, V.V. Sidorenko (Gazpromneft-Khantos LLC), M.I. Kremenetskiy (Gazpromneft NTC LLC)

Paper present bottom-hole production monitoring results in case of commingled production by ESP pumps. Particularized down-hole equipment is used for production management from commingled formations. Ways of technological improvement of measurement and interpretation are presented. Case study shows long-term bottom-hole production monitoring in case of commingled production may be used not only for production control but also for estimation of reservoir pressures and productivity index and permeability of each formation. It is also possible for multiphase flow.
