Analysis of reservoir heterogeneity and gas saturation, estimated by well logging data is a basis for reservoir management

Authors: V.V. Tcherepanov (Gazprom OAO, RF, Moscow), S.N. Menshikov, S.A. Varyagov, M.N. Kiselev (Gazprom Dobycha Nadym LLC, RF, Nadym), S.V. Afanasyev, V.S. Afanasyev (Geoinformational Technologies and Systems, LLC, RF, Moscow)

Key words: Cenomanian stage, gas reservoir, logging data, well cross section geological heterogeneity, gas flow profile, production optimization.
Efficient flow management from Сenomanian deposits at Medvezhie field in a group of wells requires consideration of variety in texture and mineralogy of rocks, determination of flow intervals in each well. Solution for the problem can be found applying results of well logs interpretation by TABC method. Reservoir modeling can serve as a merger of the obtained geological characterization and should allow for spacial heterogeneity and saturation determination in the reservoir or it's locations. The model can be taken as a basis for the whole Сenomanian gas production strategy optimization.
