- Fractal and cumulative trace analysis of wire-line logs from a well in a naturally fractured limestone reservoir in the Gulf of Mexico Klaudia Oleschko Rubén Darío Arizabalo Gabor Korvin Gerardo Ronquillo Esteban Cedillo Pardo Ciencias de la Tierra wire line logs Gulf of Mexico Statistical fractals naturally fractured reservoir We found that the wire-line well logs measured in a naturally fractured limestone reservoir show fractal behavior, and thatthe fractal parameters are correlated with the petrophysical properties. Based on neutron porosity, bulk density, gamma ray, Pwavetransit time, shallow and deep resistivity logs, five strata were distinguished corresponding to the Tithonian and KimmeridgianJurassic (JST, JSK); Upper, Middle and Lower Cretaceous (KS, KM, KI). Each of these strata has different fractal dimensions.Using the BENOIT software we obtained average fractal dimensions for the logs by modeling them as fractional Brownian motion(fBm). For the neutron porosity log D=1.70 (KS), D=1.66 (KM), D=1.75 (KI), D=1.84 (JST), D=1.67 (JSK). We conclude that thefractal geometry of the pore space controls the log fluctuations as well as the fractal dimensions of the logs in each geological unit.Cumulative trace analysis has provided further insight, including zonation of the five main units. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843311 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.43
