Theme of the paper is the solution of flooding geomodels creation for Dniester river basin territory, which uses contact and remote measurements. Natural and anthropogenic factors causing groundwater level rising were analyzed for localization of flooded zones and forecasting of geometric characteristics. Geographic information systems for researched area include the spatial binding of the hydrological elements and observation points, digital model of relief preparation, basin allocation catchment, flooded areas modeling. Structural features include the size and shape of object, brightness disposal within the object, image texture, some others. Possibility of available remote sensing data use allows reducing temporal and economic cost for conducting additional ground measurements for possible flooded areas determining. These methods of geomodels creation are realized for the territory of Dniester Canyon, the hydrogeologic feature of which is connected to the Upper Cretaceous horizon and groundwater.

Quantitative method for determining the solution error of the inverse problem in the electrometry of oil and gas wells

2021

View full text Add to dashboard Cite

Determining the quantitative degree of connection between logging error and the corresponding error of oil and gas wells electrometry inverse problem solving is considered. A quantitative method to determine the magnitude of the error of solving the inverse problem depending on the magnitude of the logging error for a given model of a single layer or section as a whole is described. Examples of determining the error of the inverse problem for real well materials, taking into account the actual measurement error, are given. A method for determining the characteristics of the spatial resolution of electrometry methods is described. Examples of its use for low-frequency induction logging equipment are given. The proposed methods allow to determine the areas of equivalent solutions and the areas of existence of stable / unstable solutions of the inverse electrometry problem.

The mobile environmental monitoring system is aimed at increasing the processing speed of measurement analyzes and increasing the scale of the study. The algorithm of analysis and modeling of extreme floods includes: construction of a series of hydrographic maps of the largest floods and graphs of characteristic water levels, assessment of the peculiarities of floods, formation of a database on channel morphometry and the state of flood objects. An important role is given to the assessment and forecast of the state of the Dniester and anthropogenic impacts on it in connection with such indicators as morbidity and control of pollution caused by flooding. Man-caused ecological safety of use of hydro resources and hydroecosystems in general should be based on the hydroecosystem concept of balanced nature use. GIS technologies (ArcView GIS 3.2a) were used to directly implement the tasks of estimating the time of penetration of pollutants into groundwater. The evaluation of the protective properties of the rocks of the aeration zone was performed by creating a spatial model to determine the relationship between objects using the module Georgesessig ArcGIS. Survey materials allow you to create 3D terrain models with an accuracy of 15–20 cm and aerial mosaics at a scale of 1: 1,000 – 1: 5,000.
