Detection of fractures in resistive image logs using Hough Transform
C. R. de Moraes, Abel Carrasquilla · 2017
The extraction of hydrocarbons requires the determination of the properties of a reservoir efficiently, and, as a consequence, it is necessary to continuously improve the technologies capable of executing this task. The resistive, density or acoustic reflectivity image logs have, at present, a fundamental role in the characterization of reservoirs, being the resistive ones represents an evolution of dipmeter tools of high resolution (micro electrodes) and laterolog (macro electrodes). This work validated a methodology for the characterization of reservoir rock fractures in resistive images. For this, a program was developed that used the Hough Transform to analyze fractures in logs in a semi – automatic way. In order to validate the methodology, the results obtained were compared with those of the literature and with the analysis done by a geologist, and it can be said that the results were satisfactory for the analyzed data, when determining the same number of fractures in both cases.
