The use of wells with horizontal endings is one of the key
trends in efficiency enhancement of oil and gas deposits development. It is
known that oil recovery factor of such deposits rarely exceed 0,3 and that fact
is explained by the complexity of choosing the optimal technology of
oil-saturated area development, complications while operating the wells,
including the horizontal ones, associated with the breakthrough of bottom
water and gas. In this regard, substantiation both the design features and
the spatial arrangement of horizontal wells and technological modes of their
work is of some interest. The article deals with the problem of determination
of limiting water-free and gas-free production rates based on analytical and
hydrodynamic models.
Key words: oil and gas reservoir; horizontal well;
limiting flow rate; coning.

The article describes some method applied to increase the degree
of development and intensification of reserves recovery by adjusting well
spacing in accordance with the principle of directions refraction of the
preferable filtration. Filtration flows directions are determined on the
basis of the vector field in the reservoir pressures within the frames of
relatively permeability-homogeneous site. The approach allows assessing the
impact of each well on the site under consideration and selecting the most
appropriate point to break the field vectors at the place of their greatest
rarefaction, i.e. to apply the standard methods of work with the wells fund
to intensify oil production and bring into production previously non-drained
reserves.
Key words: oil; extraction; intensification;
reserves; oil recovery; wells fund; filtration flow.

Analysis of influence of Yu1 layer structural parameters
on its petroleum potential is conducted by applying probabilistic-statistical
methods. The following characteristics of Yu1 layer: absolute
marks of the top of koshajsky, savujsky, sambursky, komsomolsky, urevsky and
samotlorsky beds, bazhenov suite and Yu1 and Yu2 layers
were used while researching. Individual and complex probabilistic-statistical
models of petroleum potential prediction of Yu1 layer were built
depending on its structural parameters.
Assessment of prediction reliability using the developed
statistical models is carried out. The total identification of the standard
sampling when applying the model comprising a set of parameters makes 84 %.
Computing is done and probability map of prediction of oil and gas potential
in Vostochno-Yanchinsky area is developed.

Regular zonal changes of rocks physical-chemical properties
towards the extended faults allowed substantiating normal-fault series of
different productivity. It is proved by the example of Vategansky field. Such
an analysis becomes possible due to achieving of a high level of a deposit’s
studying and the availability of a sufficient number of wells. As a result,
depending on the space inter-fault width, nearly three productivity rows
(width from 500 to 1000 m) of wells, developing some part of the deposit with
different coefficients of oil recovery (COR) are revealed. Recommendations on
rational exploitation of wells for each zone of productive rocks development
with different reservoir properties and productivity indices are given.
Key words: normal-fault area; vertical cracks;
reservoir pressure; fracture; faults; well productivity; oil recovery rates;
COR; oil production.

The article presents some method of solving the problem of water
injection control to improve oil recovery and to enhance oil production at
large mature fields, when the loading level of the systems used for
collection, preparation and pressure maintenance does not allow free
re-direction of water volumes and construction of new booster pumping
stations (BPS) and sewage pumping stations (SPS) is not economically justified
or temporarily impossible. Severo-Pokursky field served an example for
selecting five cluster sites to accommodate pipe water separators in order to
provide preliminary water discharge. Thus, cluster sites either completely or
partially are cut off from the general system of collection, preparation and
formation pressure maintenance so there appears possibility of water
injection increase which leads to additional oil production in the amount of
3,5…27 thou. m3 within 5 years.
Key words: oil recovery enhancement; pipe water
separators; injection control.

Results of the carried-out laboratory testing of the acid
compositions developed especially for application conditions in carbonate and
terrigenous collectors of the Timano-Pechorsky oil- and gas-bearing province
(Kyrtaelsky, Pashninsky, Haryaginsky oil fields) as well aso the acid
compositions currently used for these collectors treatment are presented in
the article. The main physical and chemical characteristics of the presented
acid compositions and their compatibility with the fluids (oil, water)
saturating the layer and muffling liquids various in density and structure
are revealed. The solvent characteristics of the acid compositions under
study are defined on the carbonate rock of the core. The article suggests
some methods of carrying out a number of experiments on the researches aimed
at determination of physical and chemical parameters of acid compositions,
thermal stability of acid structures, compatibility of acid compositions with
oil, reservoir water and muffling liquids, secondary sludge formation by
results of reactions, solvent ability of acid compositions defined on a core
of a collector rock. Some recommendations on acid compositions injection into
a layer are given to achieve bigger efficiency from performing of a
collector’s acid treatments.

This paper suggests some method of influence on oil reservoirs
with microbiologically active systems. Formulation of composition for
microbiological influence on oil reservoirs is developed on the basis of the
experimental laboratory studies. Practical field application of the
composition can be accomplished by mixing of culture fluid (excessive
activated sludge) in the ratio of 1:1:1 on the surface and culture medium
ingredients (molasses and washing water left after olives production) as well
as by its injection into the formation followed by incubation period of about
20 days.

annular pressure, identification of gas samples is carried out on the basis
of the data of complex geochemical studies (chromatography and
chromatography-mass-spectrometry analysis, the definition of the isotopic
composition of methane carbon). Their genetic relationship with the deposits
of nizhneberezovsky sub-suite and Cenomanian commercial deposits is
determined. The importance of creating standard gas facilities while carrying
