Horizontal well inflow profiles and composition: Thermal method improvements

Panarina E.P. (Gubkin State Oil and Gas University, RF, Moscow)

This study focuses on downhole logging issues. When finding well inflow profile and composition, temperature survey typically poses the most information loads. Field research history evidences high potential capacity of this method. In particular, its sensitively, unlike flow metering, is believed sufficient for diagnostics of lower intensity inflows. However, temperature log quantisation appears to pose numerous difficulties. The key one stems from interpretation ambiguity mostly attributable to numerous concurrent impacts on thermal field which are sometimes difficult to discriminate in actual well conditions. Specifically, this tends to undermine horizontal well study performance in a multiphase inflow environment. This paper considers temperature survey applicability areas and its enhanced opportunities.
