ABSTRACT

Highly viscous heavy oil and natural bitumen contain 60 chemical elements; most of
them are rare and precious metals in conditioning concentrations (vanadium, nickel,
titanium, etc.). Oil or bitumen rocks are to be considered not only as alternative sources
of oil and petrochemical raw materials, but also as material for construction industry,
i.e. integrated waste-free raw materials.
Feasibility and economic efficiency of heavy crude oil and natural bitumen field
development is determined by geological and physical conditions of their occurrence,
reservoir data and physical-and-chemical characteristics of oils, as well as the results of
their processing and treatment. Abnormal oil properties, especially high viscosity (low
flow characteristics) and density, are among the main factors.
Field development methods can be divided into two large groups. The first group, (no
fluid flow) oil or bitumen is extracted together with the rock containing them with
further hydrocarbon recovery under plant conditions. The second group (fluid flow) oil
is drained from the reservoir without rock removal to the surface. The paper considers
classification of available methods and the criteria for a method selection.
