On the issue of the methodology for lithologic and petrophysical studies of stone material (in the process of oil and gas wells drilling)

This article discusses some aspects of the methodology for preparing sludge and core samples for lithological and petrophysical studies. Methods for obtaining rockmaterial(sludge, core) are described interms of determiningthemoment of openingthe reservoir layer,tyingthe core in depth, and sampling the sludge. A sludge collector has been proposed that makes it possible to obtain sludge of overall fractions washed from the drilling fluid.

Prospects of Geological Modeling of Oil and Gas Bearing Reservoirs While Drilling

In this paper, we consider the technology of geological modeling of oil and gas reservoirs, based on the results of interpretation of the mud logging and well logging data. Informative geological and geophysical parameters for distinguishing marking horizons were determined. A technological scheme for opening productive reservoirs is proposed, based on the allocation of reference layers of different levels.
