On the example of the group of fields in the West Siberia North the basic types of secondary changes in reservoir rocks are reviewed. Some of the most common types of such changes in the West Siberian plate territory include the processes of zeolitization, carbonation and leaching. These processes have, as a rule, a regional character of distribution and are confined to the tectonically active zones of the earth's crust. Due to formation of different mineral paragenesises the secondary processes differently affect the reservoir rocks porosity and permeability: thus, zeolitization and carbonization promote to reducing the porosity and permeability and leaching improvement. All this, ultimately leads to a change of the oil recovery factor and hydrocarbons production levels. Study and taking into account of the reservoir rocks secondary change processes can considerably influence on placement of operating well stock and on planning of geological and technological actions.

The article describes the experience of implementation of repeated FHF with reducing the proppant mass in the fields of LLC “RN-Purneftegas”. A new approach is justified towards performing the repeated FHF in wells where a risk of the fracture breakthrough into the injected water front remains. The pilot operations proved a possibility and necessity of reduction of proppant amount used at repeated FHF run for additional recovery of oil reserves at a later stage of wells development.

This article subject of study is a method of retrieving the stuck flexible pipe during the inactive well rehabilitation in the process of string side-hole drilling under the abnormally low reservoir pressure conditions. It is mentioned that the most common are methods using a flexible pipe which are related predominantly with the bottomhole flushing to remove clay-sand bridges, thawing the hole to eliminate hydrate-paraffin deposits, the bottomhole zone treatment with chemical compositions. It is emphasized that there is not enough experience of side-hole drilling using a flexible pipe and practically no experience of fishing with the help of flexible pipe.

An equation is proposed for constructing a theoretical pressure build-up curve, which takes into account the effect of the well storage capacity, skin effect and presence of condensate in the bottomhole zone. A method was developed to determine the pressure variation during the gas-condensate well inflow and pressure build-up test, that reflects the effects of condensate dropout and retrograde transition to the gaseous phase.

An algorithm has been developed, and a method of calculation of wellhead temperature in gas wells has been realized based on the geologo-technological model.

The Bazhenian deposits which are developed by a perspective thermal method known as in-situ combustion process are described. This technology is analyzed as well as the fuel sources in case of its implementation in the reservoirs under study. Based on the result of the analysis of the expected amount of carbon residue a conclusion is drawn about a basic fuel source for the in-situ combustion process.

The article is based on the practical experience of the Tivanskoye oil field geological model construction. The main part of the article is dedicated to the problem of creation of the WOC (water saturated contact) surface taking into account a significant gradient of the WOC’s depth marks over the field area. The possibility of a block-type structure of the deposit and a plicated type is considered as the most probable hypotheses. As a result a comparison is made of the forecast on the absolute depth mark of the WOC for each of the models and the actual information is presented on the results of pilot wells drilling.

It is known that development of gas, gas-condensate and oil deposits is related with production of associated mineralized water. For creation of highly profitable processes of production and processing of hydrocarbons the methods of utilization of secondary sources of raw materials and energy become very important.
