The problems of efficient use of the tumenian reservoirs at final stage of low-pressure gas production and prospects in their solutions
- Authors:
- O. E. Bugriy
The reserves depletion estimation is presented for main (base) fields in the north part of the Tumenian area. The significance of long time production of base fields is shown. The main problems of efficient use are shown for reservoirs at final stage of low-pressure gas field. The methodology associated with solving the problem is formulated for low profitability in low-pressure gas output. The recommendations for State support of subsurface users are prepared for efficient low-pressure gas production and efficient use of reserves at all.

Complex geological engineering and geoenvironmental monitoring as a basis for creation of strategy of Saint Petersburg architectural and historical monuments conservation
- Authors:
- A. V. Shidlovskaya
In the paper concept and structural of complex engineering geological and geoenvironmental monitoring of architectural and historical monuments are considered. The specificity of engineering geological and hydrogeological conditions by the example of the Isaac Cathedral, the Kazan Cathedral and the Peter and Paul Cathedral is analyzed. The geoenvironmental condition of architectural and historical monuments underground space is estimated. The factors which influence on monuments deformation due to the high degree of underground space transformation and activity of negative natural and technogenic processes are shown. The system of impact monitoring of the Isaac Cathedral, the Kazan Cathedral and the Peter and Paul Cathedral is proposed.

Geomechanical substantiation of parameters of the fastening of railway tunnels in the conditions of the North Caucasus
- Authors:
- N. A. Belyakov
The article presents the rationale of temporary supports used in the drilling of new mines, which provides for the construction of model projects of reconstruction of old tunnels. Finite-element method analyzed the changes of stress-strain state containing tunnel complex array during the drilling of new mines. Based on the analysis, a number of findings to explore the possibility of reducing the thickness of the permanent support of new mines in tunnel complex - the new tunnel, and transport and drainage culvert.

Composition of retrospective geological systems and significance of structural-tectonic factor in paleogeographic reconstructions
- Authors:
- V. P. Matveev
Models of geological objects are represented as the static, dynamic and retrospective systems. Paleogeographic reconstruction relates to a typical retrospective system. Its objective composition becomes possible on the basis of the lower rank systems: static and dynamic. Comparison between paleogeographic reconstructions in time shows the significance of tectonical factor in the forming of paleolandscape of the territory. Information on paleobiocoenosis is necessary for estimation of paleoclimate. The Author’s field investigation materials of the geological mapping on a scale of 1:200 000 at the Novaya Zemlya archipelago are taken as the basis of paleogeographic and paleofacies reconstructions.
