Horizontal wells with multi-stage hydraulic fracturing of a
formation (HW MSHF) and multi-lateral wells have been actively drilled in the
fields of LLC "LUKOIL−Western
Siberia". Implementation of these technologies provided attraction of
the Jurassic and Achimov horizons reserves into development. In 2018 the
portion of oil produced from these horizons overreached 30 % of the total oil
production of LLC "LUKOIL−Western Siberia".
Prospecting of new technologies and updating of the applied ones when
drilling wells is constantly going on in the fields of LLC
"LUKOIL−Western Siberia",
thus providing attraction of earlier non-drained reserves into development.
Well, several multi-lateral wells with multi-stage hydraulic fracturing of a
formation (MSW with MSHF) were successfully drilled and developed in 2018.
Keywords: complex design wells; multi-lateral wells;
horizontal wells; multi-lateral wells with multi-stage hydraulic fracturing

Obviously, the application of only geophysical methods allows
only an indirect assessment of the quality of casing strings cementing. The
final conclusion about the reliability of the tightness of wells’ annular
space insulation should be carried out on a combination of technological,
geophysical and field geophysical researches results. The method proposed in
the paper provides reduction of uncertainties when specifying the causes, as
well as maintenance of statistics and comparison of the quality of the work
on casing strings cementing performed by contractors.
Keywords: casing strings cementing; annulus circulation of

The construction of deep wells in the North of Western Siberia is
associated with a number of complications associated with the peculiarities
of the geological section: the alternation of clay and sand-silt rocks prone
to swelling and destruction under the action of mud filtrate. During
drilling, scree and landslides, absorption of drilling mud, oil and gas
occurrences were recorded. Taking into account the existing experience of
drilling in conditions of abnormally high reservoir pressures and high
temperatures, a drilling fluid based on potassium formate has been developed,
which has sufficient thermal stability, high density, inhibitory ability and
low resistance to the flow of the solution. The developed drilling fluid is
resistant to biodegradation, environmentally safe, contains potassium formate
in optimal concentration, which reduces the cost of the solution compared to
other solutions of similar composition.
Keywords: drilling mud; a deep well; formats; abnormally high
formation pressure; high temperature; weighted drilling mud; high inhibited
drilling mud.

The article is devoted to the actual problem of estimation of the
efficiency of water injection volumes in oil fields developed using reservoir
pressure maintenance systems. Based on the generalization of the available
experience, for the terminology unambiguity, the definitions of total,
efficient and inefficient water injection have been developed. The concept of
distribution of water injection inefficient rate into three components –
surface, technical and technological losses has been proposed. The standard
decision-making scheme that is used when analyzing the inefficient water injection,
which includes the main methods of quantifying its volumes has been
developed. The results of computational experiments on the reservoir element
hydrodynamic model and the possibility of their use when analyzing the
inefficient injection in case of the absence of an actual reservoir
hydrodynamic model or when making operational decisions are described.
Keywords: methodological approach; water-flooding; system
of a reservoir pressure maintenance; efficient water injection; water
injection losses; hydrodynamic modeling; geological-technical measures

formation hydraulic fracturing in wells with horizontal termination. The

increasing the drainage zone, including those from stagnant sections of the
formation that are multiply differ in reservoir properties. The method was
tested in five wells, where it proved its effectiveness.

Due to the low reservoir properties of the layers, occurring at
the depths of 2700 m and lower, there is a problem of the efficiency of oil
displacement by injected water. Often, the water-flooding of such objects is
accompanied by the so-called "dagger-like breakthroughs" of water
to the bottom holes of producing wells. As a result, oil-saturated zones with
non-involved hydrocarbon reserves during filtration remain in the productive
layer. In the past few years, to solve such problems, oil and gas producing
companies used sediment-forming thermotropic compositions. The paper
discusses the experience of one of these technologies’ application, which has
positively recommended itself in the fields of LLC "LUKOIL–Western
Siberia" in the field of enhanced oil recovery.
Keywords: reservoir characteristics; injectivity profile
alignment; oil displacement; redistribution of filtration flows; water
barrier; coverage of a reservoir by water-flooding; recovery of rock
permeability.

substantiation of the construction of preliminary water discharge facilities,
reconstruction of the oil collection network and the choice of directions for
well production transportation.

Based on a mathematical model, a numerical simulation of a
horizontal naturally-acting tubular system, charged by various refrigerants –
ammonia and carbon dioxide, was carried out. For each of the options, the
values of the upper and lower critical thermal loads are determined. The
temperature characteristics of the system are found when the evaporator is
exposed to a heat flux equal to the critical one.
It has been established that the horizontal natural-acting
tubular system ("HNAT") that works on carbon dioxide has lower
critical thermal loads, as well as a lower average evaporator temperature,
thus together determining a more stable operation of the system compared to
the "HNAT" system filled by ammonia.
The results obtained prove the fact that carbon dioxide use in
"HNAT" systems is more efficient. show that using. Moreover, the
result obtained can be used when projecting a horizontal natural-acting
tubular system ("HNAT") and calculating their interaction with the
facilities built in oil and gas fields. Accounting of the data obtained
contributes to the optimization of "HNAT" system installation,
which is reflected in its final cost of placement in the object and the
effectiveness of maintaining the bearing capacity of the foundations.
Keywords: field development; heat and mass transfer;
horizontal natural-acting tubular ("HNAT"); modeling; ammonia;
carbon dioxide; permafrost; foundations; bases.
