accumulated experience in development edge zones of the AV11-2
reservoir, which makes it possible to ensure profitability of production and
achieve maximum oil recovery. The efficiency of development edge zones of the AV11-2 reservoir depends on implementation of an integrated approach at main strategic areas: analysis of the reservoir, including the distribution of geological and geophysical characteristics, substantiation of the optimal wells pattern, implementation of reservoir pressure maintenance system, drilling and completion, taking into account applicable tax incentives. The solutions presented in the work were
recognized successful, taking into account experience of foreign analogous
fields. These solutions are recommended for implementation while drilling and
development of edge zones of the layer AV11-2 of the
Samotlorskoe field. Keywords: Samotlorskoe field layer AV11-2; drilling
and development of edge zone reserves; low permeability undersaturated
reservoir; facial-changeable rocks; areal rock stress (regional stress); horizontal
well (HW); multi-stage hydraulic fracturing (MSHF); substantiation of wells
pattern; increasing the length of the horizontal sections of wells and the
number of hydraulic fracturing; effectiveness of reservoir pressure
maintenance system; experience of foreign analogues. |

ivan_sintsov@mail.ru The use of carbon dioxide gas to enhance
formations’ oil recovery is often used in the world practice, but in Russia
this method hasn’t been widely used up to now. The paper assesses the
effectiveness of the of carbon dioxide gas use to achieve the effect of
mixing displacement for the Upper Jurassic deposits in the Western Siberia.
The calculations were based on the data of the late stage of the field
development with the assessment of the method effectiveness after water
injection. Potential sources of the injection of carbon dioxide gas in Russia
were considered. The calculations were performed on a sector hydrodynamic
model in the Tempest More. The economic efficiency was analyzed and the
conditions under which this method is economically viable were defined. As a
result of the researches, a new method of deposits development, implying the
injection of carbon dioxide gas under the oil-water contact into the
transition zone with the residual oil saturation, was proposed. It will allow
to obtain additional oil production and increase the
economic efficiency of the project. Keywords: carbon dioxide gas; oil; the Upper Jurassic deposits; hydrodynamic
model; effectiveness analysis; mixing displacement; gas methods; water-oil

determination of the reasons for reduction of water-intake capacity of injection wells. The most likely
cause is the low permeability of the reservoir and the hydrophilicity of the
collector, leading to a decrease in mobility during the transfer of wells for injection. According to the obtained
results, measures to intensify the injection have been recommended. Keywords: injection well; reservoir pressure; water well; colmatage of the

Zorge str., Ufa, 450059, Republic of Bashkortostan, Russian Federation The Mesozoic deposits of Grozny oil region have
been operated for a long time. They were developed under elastic and
hard-water-pressure modes mainly due to reservoir pressure maintenance (RPM)
by means of waterflooding. To define more precisely the state of the
water-flooded formations development of the Mesozoic deposits in the Grozny
oil region, the operation of all production wells that had been in operation
was analyzed: periods of flow rates decrease, of the start of water-flooding
and full watering were determined. The current position of the water-oil
contact (WOC) of wells by the percentage water content in the products is
determined. Keywords: reservoir;
waterflooding; reservoir; well; oil products; injectivity; bottomhole zone;

masvol@mail.ru Quite recently the amount of residual oil
reserves of some oil deposits in the Western Siberia was estimated by
applying a physical-mathematical model that uses statistically stable
estimates based on the production curves analysis. The results obtained were
compared with the estimates got by means of the same model use 15 years ago.
The high confirmation level based on a posteriori analysis indicates the
robustness of the technology and the feasibility of its use in oil fields
with a long history of development and a sufficiently high density of wells
to optimize development in the late stages of operation. It is essential that
the described technology provides not only an estimation of residual
reserves, but also allows to map them along an oil
deposit area. The possible improvement of this technology is discussed. Keywords: residual oil reserves; physical-mathematical model of oil
production; oil field development; PAN program. |

yyp.71@mail.ru; alina.com9@mail.ru The article considers the urgent problem of
inorganic salts generation in the bottom hole zone of reservoirs and in
oilfield equipment (particularly, in subsurface pumping equipment) during
wells operation. The process of salt formation whilst operating wells of the
Pre-Jurassic deposits of the Krasnoleninsk arch, equipped with electric
submersible electric-centrifugal pumps (ESECP), is described. The main
field-geological characteristics of the Pre-Jurassic deposits of the
Krasnoleninsk arch are listed. To evaluate the degree of salt formation risk
whilst operating oil wells of the production site in question, possible
inorganic salting by the saturation index (according to the J.E. Oddo and
M.B. Thompson method) was calculated in respect to specific field-geological
conditions) was made. The saturation index was calculated for the most
frequently found (for the reservoirs in question) type of inorganic salt
deposits – specifically for calcium carbonate. The results of the saturation
index calculation prove high propensity of the waters of the relevant
reservoirs for formation of calcium carbonate deposits. The results of the
analysis of mineral deposits sample carried out with the help of the infrared
spectroscopy method, proving that the analyzed sample was composed by calcium
carbonate (calcite) deposits are submitted. It is revealed, that calcite
crystals formation occurs at the bottom of a well, so the crystals large
enough to clog up working organs of electric centrifugal pumps pass to the pump
inlet. Prediction of the possible complications related to salting at the
bottom-hole zone of a reservoir, on the downhole equipment, is of great
importance for choosing the most effective measures for solving the problem
of inorganic salt deposits formation. Keywords: salt formation; dissolvability;
calcium carbonate; Pre-Jurassic reservoir; partial pressure; carbon dioxide. |
