The results of the development of apparatus-methodical complexes for the topical trends of geophysical borehole research, namely logging while drilling and wireline logging in cased boreholes, are presented. The complexes are based on the use of radioactive logging methods, which are effective in the presence of steel pipes in the borehole (integral gamma-ray logging, neutron-neutron logging, neutron-gamma logging and density logging).    Combined tools for logging while drilling (LWD-KPRK-48, diameter 48 mm) and wireline logging in cased wells (WL-KPRK-42, diameter 42 mm) have been developed. The grading characteristics of the tools for typical logging conditions were obtained. The main elements of interpreting-methodological support have been developed to determining the petrophysical parameters of oil and gas reservoirs: shaliness, density, porosity, type of saturation, etc.  The borehole tests have demostrated high information capacity and efficiency of developed complexes.

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.
