This study aimed to draw a parallel between the use of territory in the Extractive Reserves Rio Jutaí and the Middle Juruá, in Amazonas, making their respective analyzes between associations and productions among other factors that also make up the understanding of the productive process in resexs. Field work was carried out within these two extractive reserves, facilitating the analysis of the processes within each of them. During the study, two management models were identified in federal extractive units, where despite having the same managing institution, they have economic scenarios and s

Abstract:

Most additions to proved reserves of crude oil in the United States are associated with reserve revisions and reservoir extensions, which derive exclusively from the continuing development of known oil fields. This paper reviews the major activities pursued by oil field operators that determine the level of production from those fields. Reported reserve additions reflect the consequencies of these activities for the productive capability of old fields and, thus, should be expected to be related to the costs and benefits of investing in such activities. A simple econometric, analysis is present

Abstract:

The vast majority of hydrocarbon fields in Ukraine are at the final stage of development, characterized by complicated conditions for hydrocarbon production. The difficulty of extracting residual hydrocarbon reserves is associated with low reservoir pressures, high water cut, destruction of the bottomhole formation zone, and corrosion of underground and surface equipment. The depletion of the main fields in terms of production and reserves leads to a decrease in hydrocarbon production levels. The fields discovered in recent years are characterized by a complex structure, large depths of produc

In extremely dry years, this percentage can usually be much lower. In this regard, one of the main problems in agriculture is the preservation and rational use of productive moisture reserves.

On the basis of the generalization of experience in the development of multilayer high-viscosity fields X the influence of waterflooding in the late stage on the oil recovery factor of productive formations has been studied. By applying statistical methods of data processing the dependence of the oil recovery factor on the reservoir flushing factor, with a sufficiently high correlation coefficient, has been obtained. The dependence obtained confirms the theoretical basis of oil recovery from productive formations developed with waterflooding and can be used when designing the process on simila

Abstract:

The article deals with the problem of enhanced oil recovery (EOR), which arises in connection with the steady decline in oil production and active depletion of reserves. The water cut of production wells leads to a decrease in oil production and a decrease in the rate of recovery of recoverable reserves. Among the factors influencing this process, both an increase in the water cut of the productive formation itself and the presence of cracks in the layers below the productive formation lead to a decrease in the effectiveness of the third methods of treatment. In this case, water ingress into t

Abstract:

The lithological and facies characteristics of productive deposits significantly influence the production of oil reserves. The geological heterogeneity of a reservoir is largely determined by the conditions of sedimentation, the nature of the medium for sediment transport, and the dynamics of these changes over time. The nature of sedimentation determines a wide range of characteristics of terrigenous sediment, including the degree of sorting and sedimentation of sediments, the distribution of filtering and capacitive properties, structural and textural features, and the geometry and position

The study of the Lokbatan-Puta-Gushkhana field development issue showed that all its production facilities from the beginning of development until 1956 were developed on natural reservoir mode. Since 1956 the development was carried out with application of water impact. However, the impact was not conducted correctly. An analysis of the waterflooded facilities showed that the injection process failed to maintain reservoir pressure and there was a significant depletion of reservoir energy during development. The productive formations of the field have large oil reserves. If exploitation is carr

“Crop-forcing” is an effective technique to delay grape maturation to a period of lower temperatures, and in this way, improve grape quality. Because of the aggressiveness of this technique (removal of leaves and fruit to reinitiate a second vegetative cycle), it may affect the level of reserves and could provoke progressive vine exhaustion. The aim of the present work is to evaluate the short- and medium-term evolution of carbohydrate reserves in different plant organs and the effect of “crop-forcing” under different irrigation regimes on seasonal biomass production and its distribution.

Currently, the need for energy is growing rapidly, it is possible to satisfy this need only by involving hard– to-recover hydrocarbon reserves in the development, and only partially by using alternative energy sources. The development of hydrocarbon deposits is increasingly associated with the development of heavy oil deposits due to the rapid reduction of conventional light oil reserves. The growing demand for oil and gas is already being partially met by a significant volume of heavy oil.

Of these, 16 seem to have disappeared, while 67 other species seem to have been lost from the lowlands (where no large biological reserves exist). Due to a suggestion that human areas add species to beta-diversity, we verified that up to 79 species now present have perhaps "invaded" with human activity (and 10 others are likely to invade), a total similar to that for lost species. However, lost species are often rare and invading species often
