Based on a small oil deposit example, being a
part of the multilayered oil-gas-condensate field, located in the south of
Russia, geological and physical conditions and feature properties, which
contribute to a reservoir compaction process, that may occur during a natural
mechanism of a reservoir development with a reservoir initial and abnormally
pressure reduction are considered. Analysis results of fields’ data and
mathematical simulation makes evident the possibility of significant
influence of a reservoir additional compaction on technological parameters of
a deposit development.
Keywords: depletion
development; elastically-closed drive regime; abnormally high reservoir
pressure; reservoir additional compaction process.

Possibility of faults identification and structure determination of fault’s dynamic influence zone (DIZ) by using drawdown measurements in the well
drilled and put into production in such zone is analyzed. Several
combinations of DIZ permeability and width, eccentricity of the well location
in DIZ were examined. It was shown that in some situations the strip-shaped
nature of DIZ can be established. But in many cases such problem solution leads
to ambiguous conclusions about a fault occurrence or the form of DIZ.
Keywords: well
tests; drawdown curve; faults; fault permeability structure.

The paper considers in detail the results of
testing CRM-models application for a multi-well deconvolution of the data,
which includes down hole pressure and rates data, using the model example of
a heterogeneous by thickness and spread oil deposit with active aquifer,
complicated by non-permeable limited borders and developed by seven wells.
The method of searching for influence and self-influence functions during a
multi-well deconvolution was earlier proposed by the authors of the paper.
The reservoir parameters, obtained after interpretation of pressure drawdown
and pressure interference curves, which were calculated using a multi-well
deconvolution, are well corresponding with averaged by thickness properties
in the numerical model.
Keywords: hydrodynamic
well testing; multi-well deconvolution; CRM-model.

The paper discusses the
estimation of application of the efficiency of the thermal gas method of oil
recovery enhancement (TG ORI) in various geological-physical conditions. The
paper briefly highlights the mechanism of the treatment on a reservoir when
implementing the thermal gas method of oil recovery enhancement (TG ORI) and
presents some specific features of the technology. The Russian thermal-gas
method of oil recovery enhancement is based on the integration of the thermal
and gas methods of treatment and applied both for low permeable reservoirs
and deposits of Bazhenov formation.
The forecast of technological
parameters of experimental sites development data based on the numerical
modeling results using the thermal gas method of oil recovery enhancement (TG
ORI) allows expecting significant oil recovery enhancement due to the
application of the method as compared with traditionally used methods, thus
being required for rational sub-soils development.
The thermal gas method of oil
recovery enhancement (TG ORI) may also efficient when developing deposits of
Bazhenov formation thanks to introduction of non-drained intervals heat
transfer from the draining permeable interlayers, when the rock is
significantly heated and the reaction of kerogen pyrolysis is formed.
Keywords: method of oil recovery enhancement; low permeable reservoirs;
Bazhenov formation; thermal-gas treatment; oxygen-containing mixture
injection; kerogen-organic matter; drained and non-drained rocks; spontaneous
exothermic oxidation reactions; enhanced oil recovery.

The paper considers the main factors affecting
the transport and deposition of proppant in the fracture as well as provides
correlations that take into account these factors. An algorithm is proposed
for calculating the parameters of the hydraulic fracture and the productivity
of the well taking into account the proppant deposition of in the fracture.
Based on the proposed algorithm, calculations were carried out and a
conclusion was made about the effect of the sendimentation rate on the well
productivity.
Keywords: hydraulic
fracturing of a formation; proppant; proppant transport; sedimentation of

The article describes an approach to studying in
detail properties and location of bypassed oil zones taking into account some
initial data about unproduced oil reserves. Through a special interference
well test application on a simulated reservoir based on the existing methods
and software packages, it became possible to confirm the availability of a
bypassed oil zone and to give a reasonable estimate of its properties. At
assumption of a bypassed oil zone centralized location its permeability was
estimated, as well as dimensions and spatial orientation. This set of data
makes available oil reserves estimation of bypassed oil zone, which could be
clarified through numerical simulation.
Keywords: hydrodynamic
simulation; well tests; residual oil reserves.

The paper presents the results of studying the
influence of heavy oil non-Newtonian properties on the physical processes of
deposits development and their simulation. The theoretical information about
the non-Newtonian properties of heavy oil and modern ideas about the main
features of the development of heavy oil deposits is given. The results of
the studies of the influence of non-Newtonian properties of high-viscous oil
on the process of deposits development and its hydrodynamic simulation are
noted.
To assess the non-Newtonian properties impact on
the design, placement of the grid of wells and oil recovery factor,
calculations were made using a sector hydrodynamic model with a direct areal
five-point water-flooding system.
Also, in order to assess the impact of
non-Newtonian properties on the deposit coverage by the development,
calculations were performed on a full-scale model of one of the reservoirs of
the Northern group of fields of JSC "Samaraneftegaz".
It has been established that non-Newtonian
properties have a significant impact on oil recovery factor and cumulative
oil production. For the tested objects, it was found that the development
efficiency can be increased both as a result of compaction of the well grid
in order to develop stagnant zones, and due to specific geological and
technical measures.
Keywords: heavy
oil; non-Newtonian properties; hydrodynamic modeling; cumulative oil
production; oil recovery factor; geological and engineering measures.

The paper presents a method to be applied for
calculation of maximal local corrosion rate on pipelines internal surface of
oil gathering systems according to the data of weight measurements obtained
by means of corrosion control samples. As a parameter that characterizes the
local corrosion maximum rate, it is proposed to use standard (root mean
square) deviation of sampling of differences in corrosion rates among
different samples of corrosion control in a cassette of 10 corrosion samples.
Keywords: local
corrosion; corrosion monitoring; corrosion rate; pipelines of oil gathering
