One of the main O&G resources base development trend is involvement into production of deep located reservoirs, characterized by overburden pressure and high temperature. Main obstacle along such fields development is uncertainty of weak-cemented rock matrix during reservoir pressure changes and permeability-conductive properties changes, such as compressibility and relative permeabilities. All these data are necessary to generate physically-viable numerical models to forecast field development scenarios.
Keywords: overburden reservoir pressure; depletion drive development; low-cemented reservoir deformation; volatile oil; gas-condensate mixture; laboratory and field tests; field development scenarios generation.

This paper discusses in detail the geological-technological substantiation of non-stationary flooding of AB1 and AB2 formations of one of the oil fields of the Nizhnevartovsk arch. It is shown that the studied formations are characterized by significant total effective oil-saturated thicknesses and dissection, oil of low viscosity, and the nature of the pore surface in the rocks is hydrophilic. Based on the results of the analysis, it was determined that the geological oil reserves of the AB12, AB1–2 facilities are produced unevenly both in the area and in the section. Based on the results of a detailed study of the geological structure and analysis of the current state of development, a site was selected and a technology for improving the development of a site with high design efficiency is developed, and the technology of its implementation is shown.
Keywords: non-stationary water flooding; heterogeneity; permeability; Nizhnevartovsk arch; residual oil reserves.

Treatment of a well bottom zone by both conventional and modified acid compositions is one of the most popular and commonly used measures. One of the variations of the modified acid treatment is the emulsion-type compositions injection, containing a hydrocarbon solvent in addition to the acid, into the well bottom zone. Such compositions contribute to a more efficient solution of organic deposits and also have a number of advantages compared to conventional acid compositions. This paper presents the results of a study of the main technological characteristics of acidic hydrocarbon-containing emulsions of direct and inverse types.
Keywords: hydrocarbon-containing acidic emulsions; surfactants; hydrocarbon solvent; hydrochloric acid; asphalt-resin-paraffin deposits; corrosiveness; compatibility with oil; reaction rate with the rock.

The article describes first part of results, gathered over oil saturated formation permeability estimation research for data acquired from wells, which penetrated carbonate fractured oil saturated reservoir. Well test and open-hole logging results analysis lead to identification of data processing procedure necessary for permeability estimation of wells, which wasn’t subjected to well test. Main source of data for particular research was oil producing field, located in Timan-Pechora oil and gas province of Russia. During analysis a limits of properties for every reservoir type were identified as well as identification marks.
Keywords: carbonate fractured oil saturated reservoir; well test; permeability estimation; volume-conductivity properties.

In general, the solution of the problem of a multi-well deconvolution of data on well bottom pressures and flow rates and the search for functions of influence and self-influence is a very labor intensive process. This paper proposes a method of searching functions of influence and self-influence by using CRM-models. These models are based on the combined use of the material balance equation and the well inflow equation. The material balance equations are written separately for each drained volume, taking into account the crossflows between them and for the aquifer zone (if any). The proposed method was tested on a model example of two wells in a square reservoir with impermeable boundaries, heterogeneous in permeability. The parameters determined as a result of deconvolution are in good agreement with those actually specified in the model.
Keywords: wells hydrodynamic testing; multi-well deconvolution; CRM-model.

The paper describes the accidents of offshore stationary platforms (OSP), including those that occurred in the Caspian Sea (1962), in the North Sea (1965, 1980), off the coast of Canada (1982), in the South-Chinese Sea (1983), off the coast of Brazil (2001), etc. It is assumed that one of the main reasons for the destruction of offshore platforms structures (448 accidents over the period of 1973–1981) and capsizing (160 accidents) is bending of the blocks supporting legs due to the loss of stability of the legs’ axis rectilinear balance from the combined effect of storm waves, the forces of the legs own weight, the compressive concentrated load from the weight of the technological equipment and the weight of the upper deck and the torsion moment from the cyclonic circulation of the wind and waves. The presented calculations of the critical length (height) of the support leg of the OSP in case of the combined action of axial compressive forces and the twisting moment show that the values of the twisting moment should be taken into account when calculating and designing the parameters of the supporting legs of the OSP blocks.
Keywords: accident; offshore platform; axial forces; twisting moment; critical length of the leg; cyclonic circulation of the wind and waves.
