Some features of triassic deposits in Shebelynka field productivity

Abstract

Triassic sandstone collectors of Korenivka and Serebrjanka subsuites on Shebelynka field inclose primary gas pools of commercial character that lay over the main Paleozoic massive-formational deposit. This fact has been proved by direct gas-productivity signs, obtained during the drilling of the first deep borehole on the field - № 1 – Shebelynka. It can be used as an important analogy during the hydrocarbones exploration in Dnieper-Donets depression of Mezozoic prospect complex as an example of productivity existing above regional Permian salt impermiable seam. Also there are some serious bases for prognosis of oil fringe or oil pools in Shebelynka rock where beds are upper and lower than massive-formational pool section.
