The department of a reservoir engineering of "Ukrainian Oil and Gas Institute" is engaged in creation of constant-operating mathematical models of deposits. The mathematical models have been created for productive formations of approximately 20 deposits of Ukraine. Conditionally process of construction of geologic model can be divided into some stages which are connected among themselves: Creation of structural model of a deposit. Structural constructions are understood as structural surfaces of a roof and a base surface of interlayer and seams. Basic data for construction of structural surfaces are results of geophysical investigations of wells. Seldom, at presence, the seismographic observation are used too. Creation of a three-dimensional grid. Modeling is surveyed on a three-dimensional grid which describes internal volume of a deposit. The reservoir is divided into separate hexagon cells. The organization of seams of a grid displays the structural and tectonic effects which are available in a deposit. Modeling of space distribution of collecting properties. The purpose of this stage is getting a representation about space distribution of reservoir characteristics. Space distribution of parameters is carried out similarly to structural constructions. A small well stock often necessitates an alteration of geologic model of deposits and it happens to come back to the beginning of modeling and reconstruct models.
