results of wells operation of the regional formation AV13
in the Western Siberia fields are considered. The AV13
formation oil reserves in the drilled zones are poorly covered by the
drainage and are a reserve for increasing oil production at the facility. The
main development problems are identified as well as the advantages of
involving reserves in the drilled areas of the fields. The efficiency of the
applied technologies as well as the potential of drilling the formation by an
independent well pattern, were assessed.
Keywords: formation;
development analysis; reserves recovery; permeability; debit; development
system; multilateral well; horizontal well.

The article describes a method for building maps
of layer-by-layer and zonal reservoir heterogeneity, oil saturation, oil
displacement factor and reserves coverage. The calculations included the
object division based on the Delaney triangulation into elementary triangles
with wells located in their vertices and into non-overlapping polygons
(Voronoi regions). Based on a number of experimental data from the
TatNIPIneft, the dependence of the displacement factor on the permeability
for layer-by-layer and zonal permeability heterogeneous reservoir was
established using the example of the D1 horizon of the
Tashliyarskaya area of the Romashkinskoye field. Using mathematical modeling,
the initial recoverable oil reserves, put into development, were determined,
mobile undrained oil reserves were calculated and a map was built with the
allocation of areas for conducting various geological and technical measures.
Keywords:
enhanced oil recovery; building of maps; Delaney triangulation; initial
recoverable oil reserves.

A method for obtaining empirical curves of oil
and water relative phase permeabilities based on the analysis of laboratory
research results is considered. The application of this method will make it
possible to perform an empirical calculation of the curves of the relative
phase permeabilities at a given value of the absolute permeability, based on
rather reliable functional relationships, identified when analyzing the
results of studies of core material from the Achimov deposits of the
Imilorskoye field.
Keywords: relative
phase permeability; absolute permeability; water retention capacity;
reservoir properties; two-phase filtration of oil and water.

Over the past two decades, the structure of oil
and gas reserves in Russia has undergone significant changes: with a general
increase in reserves, a significant increase in the share of hard-to-recover
reserves (HTRR) is observed. According to the existing classification, the
sub-gas zones of a two-phase type deposits are one of the main subgroups.
The paper assesses the current state of the
reserves of the sub-gas deposits of the Perm Kama region, analyzes the
distribution of porosity and permeability of the productive formations of the
Low and Middle Carboniferous age. Viscosity values of saturating oil and
related parameters such as mobility, displacement coefficient are considered.
The sub-gas deposits of the Perm Territory are
grouped by their belonging to coeval deposits; the sensitivity of the
displacement coefficient changes to the changes in permeability and mobility
is estimated. In order to identify the characteristic features and determine
the nature of the change in the filtration-capacitive properties, the
petrophysical and hydrodynamic characteristics are compared with uniform
layers of small deposits of high-viscosity oil on the western slope of the
South Tatar arch.
The base of actually carried out
geological-technical measures (GTM) aimed at increasing the mobility is
analyzed. The multiplicity of increase in oil production rate after the use
of geological-technical measures was evaluated for the selected groups of
objects. Based on the obtained dependences of the displacement coefficient on
mobility as well as taking into account the analysis of the results of the
performed geological-technical measures, conclusions are drawn about the
effectiveness of the application of enhanced oil recovery methods aimed at
increasing the mobility of reservoir fluids. The results and conclusions are
aimed at improving the efficiency of regulation of gas and oil fields
development in the Perm Territory, selection and justification of
geological-technical measures.
Keywords:
oil-and-gas deposit; gas cup; oil rim; oil displacement; correlation
coefficient; oil mobility; permeability; multiplicity of increase of the flow
rate.

The presented article, which consists of two
parts, considers an approach to the selection of the minimum required and
sufficient number of laboratory studies on the example of calculating the
sensitivity analysis in an adapted hydrodynamic model (HDM) for an actual
experiment using the CMG stars simulator. The most significant parameters
were identified and considered: the initial permeability of the undrained
part when exposed to temperature, the initial geological porosity of the
undrained part, molar masses of coke and kerogen (kg/mol), kerogen density
(kg/m3), TOC (%) (Copr), ratios of gas, oil and coke by weight in the
equation of kerogen cracking (%). The first part of the article discusses an
approach to modeling the experiment, on the basis of which a sensitivity
analysis will be made and the hydrodynamic model will be adapted to the
actual results. Further on the influence of various necessary parameters set
in the HDM on the calculation results is considered. The second part of the
article includes the added parameters, and on the basis of all the
calculations and data carried out, a conclusion is made about a possible
optimal reduction in the number of studies at the stage of pilot work for
rocks of the Upper Jurassic deposits and the creation of a hydrodynamic model
under conditions of the minimum allowable amount of initial data.
Keywords: adapted
hydrodynamic model; molar mass and density of kerogen; modeling; research;

CHERNOMORNEFTEGAZ–DOBYCHA LLC – RELIANCE ON THE
IMPLEMENTATION
AND DEVELOPMENT OF INNOVATIVE TECHNOLOGIES IN OIL
AND GAS PRODUCTION IN THE CRIMEA (p. 47)
Roman Evgenievich Stefanov
Chernomorneftegaz–Dobycha LLC
28/10, K. Marks str., Simpheropol, 295000,
Republic of Crimea, Russian Federation.
The paper, for the first time, notes the risks
which can occur when developing oil and gas fields in the Republic of Crimea.
The economic sanctions of the United States and the European Union imposed
against the Russian Federation in terms of trade and supplies of equipment,
materials and technologies for the oil and gas industry, as well as the
territorial claims of the Ukraine, significantly reduce the efficiency of the
hydrocarbon fields development in the Republic of Crimea and especially
offshore oil and gas fields in the Azov and Black Seas. The complexity of
climatic conditions, constant changes in water temperature, directions of sea
currents, ebb and flow, storms, drifting ice, etc. require the construction
of expensive engineering structures (platforms) and long-term organizational
and technological measures, which causes high unit costs of exploration,
development and production of hydrocarbons versus the cost of exploration,
development and production of oil and gas onshore.
The promising deposits of mountainous and
lowland Crimea for the discovery of large gas, gas-condensate and oil fields
on the Kerch Peninsula: Jurassic, Lower Cretaceous and Aptian-Albian,
Maikopian and pre-Maikopian deposits (works of B.I. Deneg, S.I. Ivanov, I.F.
Glumov, V.L. Gulyaev, B.V. Senin, S.M. Karnaukhov, etc.) are mentioned. The
potential of the Kerch Peninsula in terms of hydrocarbon production in the
Republic of Crimea may exceed the potential of oil and gas production in the
Caspian Sea region. As part of the implementation of the Program of joint
activities and the Agreement between State Unitary Enterprises
"Krymgeologiya" and "Chernomorneftegaz", it is planned to
drill a deep exploration well in the Povorotnaya area for the production of
natural gas and condensate.
Keywords: Republic
of Crimea; prospective deposits; gas, gas condensate and oil fields;
exploration well.

The article presents the structure of regulatory
support for scientific research in the implementation of innovative
developments in the oil and gas industry. At a time of increasing competition
and the global energy crisis, the transformation of the domestic oil and gas
sector into a branch of modern technologies is an effective option for developing
and preserving the existing potential. Innovative activity is a part of the
state's socio-economic policy and should guarantee the development
and security of business, determine the goals and directions of development
in the form of the development of legislation, the implementation of various
forms of support in the activities of Federal and territorial state
authorities. The ongoing digital modernization provides an economic result
only in the presence of state regulation of innovative technologies and
stimulation of domestic scientific developments based on artificial
intelligence, large data sets, predictive control and modeling of
technological processes and objects. The article provides a brief overview of
the development of regulatory activities, provides examples of the
application of the best foreign practices in the field of stimulating and
developing promising technologies and industries. It is shown that providing
incentives for innovation, as part of the regulatory process, can have a
direct and indirect impact and is carried out in the form of various forms
and institutions of development.
