Application of managing structures for the organization of adaptive computing process of modeling of dragline rehandling

Abstract

The network structure of formalization of the technological scheme of mining operations by dragline was offered. The adaptive algorithms based on CASE-statements and run-time libraries are applied to carrying out mathematical calculations under control of similar structure. Division of calculate modules into a number of stages—formation of tables of basic data, a formation of tables of operating variables, calculation and record of resultant parameters and geometry in tables was proved.

Quantative characteristics of the CSP method

Abstract

The quantitative characteristics of the CSP method, which poses to estimate its effectiveness for fracture hydrocarbon reservoirs imaging using scattered seismic waves, are defined and investigated. The most important is the sensitivity coefficient, which shows how small diffractors, compared with the shadowed reflectors, may be to be detecting by the CSP method. These dependencies from acquisition geometry and other parameters are numerically studied.

An algorithm of wave equation datuming

Abstract

The article describes the wave equation datuming is the procedure in seismic exploration that used for removing of the influence of Weathering Velosity Zone. It means transform the wave field at free boundary to some level below that Zone. Numerical procedure for solving this problem based on reverse time wave continuation. The new thing is that we cut of the ghost waves using characteristics. The results of numerical modeling are represented.

Power rating of flares power burning associated gas by processing satellite images MODIS

Abstract

Described modified method for estimating flares power of burning associated gas by processing satellite images MODIS. The program complex estimates associated flared gas volume for a given torch unit and licensed areas within the selected calendar periods. The methodology and software system tested for the most powerful oil fields torch units in Western Siberia. Investigations held by us have shown that exceeding of the calculated data as compared to report information is up to 2 times.

Efficiency of the CSP technology using in Caspian region (on the example of the North Akkar oilfield)

Abstract

For the first time in the fields of the Caspian region was used the CSP technology, which makes it possible to extract the scattered waves from the full wave field. One the basis of scattered waves sections and map analysis had made the forecast of fracture cavernous reservoirs in carbonate Triassic sediments of the North Akkar oilfield. Confirmation of the executed forecast allows to recommend this technology for mapping non conventional fracture-cavernous reservoirs on other fields of the Caspian region.
