The main purpose of the theory and practice of oil field
development - the most complete and cost-efficient extraction of
oil from the depths.
Discipline "Technology development of oil fields" is
technology because it is directed at improving technology,
increasing real economically profitable oil recovery.
Oil recovery factor. Determines the degree of extraction
of oil from oil reservoirs and is a measure of the degree of oil
usage. Getting maximum value - it is one of the main objectives of
the rational development of oil fields. Oil recovery factor - its ratio
of oil produced reserves to the initial oil reserves in the reservoir.
Initial oil reserves are defined by the volumetric method
(Zhdanov‟s formula)
Q init = Fhm ρ 0, tons (1.1)

where F - oil-bearing area, m ; h – effective layer thickness, m; m
– coefficient of porosity, fractions of unity, (f.u.); ρ 0 - initial oil
saturation, (f.u.);  - average recalculating factor, (f.u.); =1/b (b –
volume formation factor);  - specific density of oil after

decontamination, t/m .
Coefficient of oil recovery depends on many factors: the
geological structure and mode of deposit; properties of rocks-
collector; its degree of heterogeneity; properties of reservoir fluids,
indicators development, drives reservoir and others. Oil recovery
factor depends on the amount of free gas, which is in the reservoir.
For determination of oil recovery used in industrial and laboratory
methods.
What does it mean developing reservoir?
Developing a reservoir to cause movement of reservoir fluids into
wells. This can be done by drilling and injection wells operating.
You need only install the needed their number, location, time of
commissioning and operating modes.
These issues must be addressed in the design of field
development system, and the system is designed to be rational. In
