Permeability is the indispensable parameter in oil and gas reservoir studies. In fact of researching and operating on oil and gas fields worldwide, there are many types of permeability. Each permeability type has a specific characteristic according to the study purpose. In this article, the specific characteristics of some typical permeability as gas permeability; water permeability, effective permeability; relative permeability … will be analyzed, especially concern to the role of each permeability type in oil reservoir study to assisting researchers has an overview to orient their study.

Abstract For controlling the oil field development proposed an economically efficient express calculation and visualization method of the hydrodynamic parameters current values distribution in the productive formation. The presented report shows the results of applying this technique for determining the injected water propagation direction into the productive formation (X horizon) at the «Neft Dashlary» field. Based on the calculated results, the current distribution of the injected water was visualized in the selected section of the formation. High accuracy of the calculation was confirmed by comparing obtained results with the results of a simultaneous tracer study conducted in the field conditions. During tracer studies it was tested a new tracer material, more effective than its analogs. According to laboratory and experimental studies, the addition of 0.003% of this indicator substance to the volume of injected water is the optimal amount for its recognition in the well's product. At the allocated area of the "Neft Dashlari" field, the benefits from the use of the calculation method amounted to 62.9 thousand manats. Based on the obtained satisfying results of the new method for calculating hydrodynamic parameters and the use of a tracer indicator application at the «Neft Dashlary» oilfield, it is recommended to apply these developments in other oil and gas fields for mass diagnostic of the reservoir fluid distribution in a selected area of productive formations.

Aim. In this paper, we set out to analyse the problem of preservation of old‐growth relic pine forests under in the context of oil field development.Discussion. The Buzuluk pine forest is the largest natural island forest in the steppe zone of European Russia. Presenting a landscape isolate of old‐growth natural pine and pine‐broadleaved forests, this unique natural object received the status of a national natural park in 2007. In this territory, former oil and gas fields are currently being prepared for operation and maintenance. The Buzuluk pine forest has been a subject of intense scientific interest due to a number of preserved standards of old‐ growth pine forests. These standards were originally identified and described by G.V. Morozov and V.N. Sukachev, thus forming a basis for modern forest biogeocenosis classifications. The paper discusses the current problems of the Buzuluk pine forest associated with the need to preserve old‐growth pine trees serving as standards. The consequences of oil production are assessed, with environmental restrictions in the zones of oil field exploitation being formulated. Industrial development of oil and gas fields inevitably leads to negative consequences, includ‐ ing the loss of ecosystem stability, a decrease in biological diversity and landscape degradation.Conclusion. The preservation of old‐growth pine trees is a necessary condition for the existence, restoration and sustainable development of the Buzuluk pine forest as a single ecosystem.

Partial Destruction

Partial destruction of cement stone or an increase in its permeability during the development of oil and gas fields is a frequent occurrence. There are a huge number of natural and man-made factors that lead to an increase in the gas permeability of the cement ring. This article attempts to investigate the permeability of cement stone in active and abandoned wells. It presents an overview of experimental works devoted to determining the real permeability of cement stone on samples and according to the results of studying the state of wells in various conditions.

The Permian succession in the southern Taroom Trough is generally believed to be the source of hydrocarbons in the Roma Shelf oil and gas fields and the Moonie oil field. The succession is characterised by complex relationships between marine and fluvio-deltaic facies which reflect marked differences in the depositional history of the Trough.On the basis of transgressive events, the succession has been subdivided into four sedimentary cycles, the boundaries of which do not always correspond to formation boundaries or seismic horizons. Notably, the top coal in any area forms a prominent seismic reflector, but coals in individual areas can be demonstrated to occur at different stratigraphic positions relative to the major interval of coal development. These higher coals reflect changing depositional settings with time.Palaeogeographic reconstructions demonstrate a complex depositional history of sediment input onto a shallow shelf from differing directions and with different rates of input.

Porosity Model

In Fuyang oil layer, the later-period structure is complex; the reservoir is mostly composed by river-way sand; the oil and gas reservoir is significantly concealed, so it is greatly difficult to identify. To accurately describe the reservoir, facies controlled reservoir is simulated stochastically using Geocad software in the study area: Lithofacies is first established using Gauss truncation algorithm to construct a facies model of mudstone, dry sandstone, poor sandstone, and sandstone, and its fitting rate is 0.814, and then a porosity model is established using sequential Gauss method under the constraint of the lithofacies model and its fitting rate is 0.814, and its correlation coefficients are as follows: 0.845 is for sandstone; 0.893 is for poor sandstone; 0.915 is for dry stone; a permeability model is established using cloud transformation method under the constraint of the porosity model and its fitting rate is 0.732, and its correlation coefficients are as follows: 0.695 is for sandstone; 0.734 is for poor sandstone; 0.824 is for dry sandstone. These prove that the facies controlled reservoir modeling based on Geocad plays a significant role in the areas where the later-period structure is complex and sand is thin and changed intricately. Thus, the needs of the oil field exploration and development can be fulfilled by the model to a certain extent.

The Impact

In the process of extraction, collection, transportation and primary processing of hydrocarbons, the lands of the fields are often damaged. For the further operation of the oil field, it is necessary to carry out not only reclamation of disturbed lands, but also oil-contaminated lands formed as a result of accidental spills. The natural environment of Western Siberia is a fragile environment and interference in its existing balance as a result of accidental spills of oil products and pollution of land and water bodies leads to negative consequences for the flora and fauna. If the impact on the natural environment during the development of oil and gas fields during the placement of oil field facilities can still be considered as permissible, then the ingress of oil products into the environment should be considered as negative with far-reaching consequences.

Favorable Conditions

This paper provides compelling evidence for the previously discovered oil and gas fields in the central, most uplifted part of the Nepa–Botuoba anteclise, to be the constituent structural elements of the Erema–Chona giant gas–condensate–oil field. The revealed tectonic, lithological–facies, and geochemical affinities within its limits attest to equally favorable conditions for the formation of oil and gas accumulations.
