 The main task of the engineer engaged in the calculation of the development of an oil field is to draw up a calculation model based on individual concepts derived from a geological-geophysical study of the field, as well as hydrodynamic studies of wells.Modern computer and computational achievements make it possible to take into account the properties of the layers and the processes occurring in them when calculating the development of deposits with considerable detail.The possibilities of geological, geophysical and hydrodynamic cognition of development objects are continuously expanding.
