The article is devoted to the development of the theory of nonequilibrium pressure and temperature fields in two-phase thermodynamic systems simulating natural oil and gas reservoirs. Such systems are classified as strongly dissipative, since the flow process is accompanied by the predominant action of internal friction forces. The studies carried out made it possible to significantly clarify the concept of thermodynamic processes and establish new physical laws governing the formation of temperature effects during fluid filtration in real porous media. It is shown that the maximum values of the temperature effect do not reach the value of the integral Joule - Thomson effect for any values of the parameters of the medium and liquid, and in real oil and gas reservoirs, temperature changes are several orders of magnitude smaller than those predicted on the basis of the equilibrium theory.

Longitudinal Fractures

The purpose of modelling the fractures is to create simulation properties with the power to predict the reservoir behaviour. Petrel software is one of the best softwares in the market that can do this task very well, but there is no available educational paper for every researcher. Therefore, in this work, a fracture modelling job was done in one of the most important Iranian fields using Petrel software and image log data. The purpose of this work was  to determine the new information of the fractures in Gachsaran field and also to prepare a valuable educational paper for other researchers who are interested to learn about the fracture modelling. This work revealed that in this field, the longitudinal fractures had been parallel to minimum stress (Zagros trend), fracture intensity was the nearest to the major fault and northern flank, fracture porosity was 0-7%, fracture permeability was 0-6000 MD, and more valuable information is provided in this paper.
