Combining layers 1 and 2 in one object development due
to the fact that they have similar values of permeability and
viscosity of the oil, and are a short distance from each other
vertically. By this recoverable reserves of oil in the reservoir 2 are
relatively small.
In addition, if the layer 3 contains low-viscosity oil can be
developed using conventional water flooding, then the
development of layers 1 and 2, which marked the high-viscosity
oil, will have to apply from the beginning of the development of
other technology.
However, it should be noted that despite the significant
difference of parameters of layers 1, 2 and 3, the final conclusion
of the selection of objects taken from the development of
technology and technical and economic indicators of options
combining layers in object development.
Objects development is divided into the following types:
independent, that is being developed now and back object, that is
the one that will be developed wells are currently operating in
another object.
