Wettability and formation conditions of reservoirs

Abstract

The analysis of the relation between the wettability of mineral substance, the porosity and permeability properties of the rock and the nature of the distribution of hydrocarbons was made based on the core samples of the BS-1 and BS-2 productive strata of the Surgut oil and gas field. It was proposed to study the association of hydrophobic, hydrophilic, and mixed groups of collectors to different facies.

Prospects for the use of advanced computer modeling systems in planning geological and technical activities

“…The inclusion of repair and insulation operations in the modern list of key technologies necessary to restore and increase productivity (increase the inter-repair period) of wells in conditions of low downhole pressures is a forced method of regulating oil recovery of depleted facilities. At the same time, a key component of the trend of increasing the percentage of repair and insulation work carried out at the fields is not only the construction of wells of complex design with a large deviation from the vertical, which drain poorly permeable and complex oil formations (deposits) related to transitional oil and water facilities with a powerful gas cap, but also significant changes regarding the development of hard-to-recover reserves and their subsequent extraction [12][13][14].…”
