Participation in these conferences not only gives
students the opportunity to learn more deeply
about the subjects taught, but also helps them
expand their worldview, develop analytical
thinking skills and enrich their knowledge in
scientific and technical fields.
I think that such conferences provide a unique
opportunity for students to share their knowledge
and experience and, at the same time, they invite
attention to the social relevance of scientific
activities.
I wish each of the conference participants a
fruitful exchange of experience and knowledge.

The three-dimensional distribution and manifestation of reservoir
heterogeneity and petrophysical parameters are crucial information provided
by reservoir characterization. This is done by integrating petrophysical
properties determined by various techniques (core analysis, well logging,
and well production data) to geological properties. Reservoir models must
also predict changes in reservoir properties and their implications for
reservoir performance.
To give an example for reservoir characterization of shallow marine
sandstones, certain fields as the case study have been analyzed. The Intra
Draupne Formation sandstone in the Upper Jurassic of Johan Sverdrup field
(North Sea, Norway) is made up uncommonly coarse-grained siliciclastic
sediments, where mean net/gross rate is 97% and mean porosity is 28%,
and it has remarkable high aerial distribution, net/gross, lateral continuity,
porosity and permeability. Individual wells' medium core permeability varies
between 0.5 and 40 Darcies. Reservoir is considered time-transgressive
sheet with thickness varying within the interval of 2 and 38 and covers an
area of greater than 200 km2. The upper part and lower part associations of
facies within the Avaldsnes High region in eastward have the greatest
median permeability figures of 25 and 27 Darcies, respectively. Within
Augvald Graben region to the west, upper part and lower part associations
of shoreface demonstrate average rates at 15 and 21 Darcies, accordingly.
The Intra-Draupne Formation is excellent reservoir because of its wide sheet-
like distribution of siliciclastic deposits[1].
The Kaimiro Formation is considered to be part of the Kapuni Group
within Basin of Taranaki (New Zealand), made up primarily of sandstone and
variety of seaside plain to facies of shallow marine environment. The
petrophysical properties porosity and permeability, as well as their derivatives,
are fully interpreted. For a better comprehension of parameters affecting
reservoir quality, petrographic and sedimentological descriptions of some
chosen thin sections from the examined wells are also utilised. This is
consistent with other data, which reveal that formation is considered to have
ideal mean porosity of 19.6% and ideal mean permeability of 879.45 mD,
