Geologic exploration analysis, efficiency evaluation, and success rate improvement

Authors: V.G. Bazarevskaya, T.I. Tarasova, A.N. Troitskaya, O.V. Presnyakova, A.F. Abdrashitova (TatNIPIneft, RF, Bugulma)

Key words: geologic exploration, drilling, South-Tatar Arch, structure, seismic density, reservoir, velocity anomaly, Kamsko-Kinelsky trough system.

One of the ways to reduce geological risks during exploration and prospecting

is to analyze earlier exploration data covering a large number of oil-bearing

structures, as well as those structures which didn’t prove to be oil-bearing.

This paper reports key reasons for unsuccessful wildcat drilling in South-Tatar

Dome area, presents the results of comparison against successfully drilled

structures and proposes solutions to improve exploration success rate.
