Application of electrical prospecting methods to petroleum exploration on the northern margin of the Siberian Platform

Abstract

This paper considers the potential of modern electrical prospecting methods for evaluating oil and gas occurrence on the northern margin of the Siberian Platform—a vast region from the Gydan Peninsula to the mouth of the Lena River. Results of regional electrical surveyes over the past 12 years in this region are generalized. The capabilities of electrical prospecting for solving the following four problems are defined: survey, in conjunction with seismics and drilling, in the Jurassic–Cretaceous part of the section; study of the structure of the Paleozoic sequence; study of the junction zones of large geoblocks and deep structure of the Earth’s crust and upper mantle; and study of the permafrost. © 2018, V.S.

Fine Detection and Analysis of Hidden Karst in Wellsite with Quasi-Three-Dimensional TDEM Based on Lateral Constraint

“…TDEM have made great progress [12,16,[27][28][29][30][31], they have not been popularized and applied due to the large amount of calculation and the limitation of computing platform. Therefore, considering the poor continuity, strong heterogeneity, and difficult identification of hidden karst geological body, based on the regularized one-dimensional inversion, this paper introduced horizontal constraint inversion to simulate three-dimensional inversion, so as to suppress the unreasonable phenomena of inversion model mutation caused by single-point noise and effectively identify hidden karst geological body in the wellsite.…”

Hydrogelogical characterization of a waste rock pile and bedrock affected by acid mine drainage from geophysical survey

“…The different materials that compose the local geological context can be distinguished from the contrast between their physical properties, whose parameters can be measured using indirect investigation methods, which include geophysical methods. Geophysical surveys are widely used and they are applied to a great number of scientific fields, as mineral prospection studies [34][35][36], petroleum geology [37][38][39][40], geotechnical engineering [41][42][43], and hydrogeological and environmental studies [44][45][46]. They are usually associated with conventional direct investigation methods, like monitoring wells, drillings, soil probing and trench [47][48][49].Considering all kinds of geophysical methods, the geoelectrical ones are the most valuable for environmental studies, especially the direct current (DC) resistivity method.…”

Polímero Sulfonado Utilizado Como Catalisador Heterogêneo Na Reação De Esterificação

“…A pesquisa realizada por Afanasenkov & Yakovlev (2017), estuda o potencial do uso da técnica da geoprospecção elétrica na exploração de jazidas de petróleo e gás e ainda demostra um meio para utilizar as duas técnicas (geoprospecção elétrica e sísmica) em conjunto. É um estudo realizado na margem norte da Plataforma Siberiana e mostra os resultados dos últimos 12 anos de pesquisa naquela região.…”
