The paper presents the results of researches on the specification of clay components, as well as the zones of intra- and interstratal fluid flows in the formation processes of oil-gas fields. The investigations have been carried out in the context of Sangachal-Duvanny-Khara-Zira (SDKhZ) field, located in Baku archipelago of South Caspian basin (SCB). It was defined that the presence of clayey chlidolite in the reservoirs are observed more effective in the values of permeability rates. The zones of intra- and interstrata of fluid flows in the reservoirs were specified based on the lithological model of productive horizons. Therefore, the presence of closed migration-flow (drainage) system both within productive horizons and in the scale of reviewed field was supposed. In support of these assumptions, 2D and 3D variation models of flow zones indicator values for intrastrata levels of productive horizons and for the section fragment of SDKhZ field have been developed.

The relevance of the article is associated with the importance of the object of the research. Dozens of unique and giant oil and gas fields, such as Urengoyskoye, Medvezhye, Yamburgskoye, Vyngapurovskoye, Messoyakhskoye, Nakhodkinskoye, Russkoye, have been identified within the Cenomanian complex. The main feature of Cenomanian rocks is their slow rock cementation. This leads to significant difficulties in core sampling and the following studies of it; that is the direct and most informative source of data on the composition and properties of rocks that create a geological section.The identification of the factors, which determine the slow rock cementation of reservoir rocks, allows establishing a certain order in sampling and laboratory core studies. Consequently, reliable data on the reservoir and estimation of hydrocarbon reserves both of discovered and exploited fields and newly discovered fields that are being developed on the territory of the Gydan peninsula and the Bolshekhetskaya depression will be obtained. This study is also important for the exploration and development of hydrocarbon resources of the continental shelf in the waters of the Arctic seas of Russia as one of the most promising areas.As a result of the analysis, it was found that the formation of rocks of the PK1-3 Cenomanian age of the Bolshekhetskaya depression happened under conditions of normal compaction of terrigenous sedimentary rocks that are located in the West Siberian basin. Slow rock cementation of reservoir rocks is associated with relatively low thermobaric conditions of their occurrence, as well as the low content of clay and absence of carbonate cements. Their lithological and petrophysical characteristics are close to the analogous Cenomanian deposits of the northern fields of Western Siberia and can be applied to other unconsolidated rocks studied areas.

This study was conducted to assess the building coverage and environmental quality of residential area in Nkpor Uno Idemili North L.G, Nigeria. The study employed a descriptive survey design to find out level of compliance of buildings to planning regulations. One hundred and eighty (180) were interviewed using a modified instrument (questionnaire). The data collected were coded into SPSS and analyzed with descriptive statistics. The results showed that 72(40%) reported inadequate setback as a major effect of over built buildings, 55(30.6%) reported inadequate free air space, 37(20.6%) said inadequate ventilation and lighting. Also, the nature of drainage system provided in residential areas; 76(42.2%) has no drainage system, 70(38.9%) has close drainage system. The building coverage of residential houses in the study area; 60(33.3%) has their building falls under 51-75% for over built, 48(26.7%) has their building falls under 76-100% for overbuilt. For the factors influencing the percentage of area built upon, 57(31.7%) has greed and no money to acquire a large plot of land, 47(26.0%) has no land space to built their desirable house. Then, non adherence to provision of adequate ventilation and lighting in the residential houses in the study area affects the dwellers’ health and such factors can promote communicable diseases. In conclusion, it was observed that the compliance rate was not encouraging because the planning regulations recorded very low compliance as include set–back from property boundaries; inadequate free air space; lost of aesthetic values, and inadequate ventilation and lighting. Therefore, government should embark on enforcement of land use plan, and strategic plans for various towns and villages to accommodate its utilities and facilities.

Due to the high degree of production of oil reserves in Western Siberia, geological exploration has been carried out mainly on complex objects for the last 10 to 15 years. The complexity of the task increases because of the fact that the predictive properties of seismic data on such objects are not high. All this leads to low efficiency of geological exploration.In order to increase the efficiency of geological exploration of complex objects, we have proposed a methodology, in which, based on the results of a comprehensive analysis of diverse geological and geophysical information, a model of the quality of hydrocarbon reserves has been built. The ranking of the zones of the quality map of reserves will justify the most effective strategy of geological exploration, that is, the strategy with the least risks. In proposed methodology, special attention is paid to assessing the economic impact of involving reserves in industrial development. Testing of the methodology on reservoir rocks of the J2/1 layer within the Surgut arch has showed its rather high forecast properties.
