ABSTRACT
The objective of this work is to establish a sequence of interdependent processes through the incorporation of unconventional techniques, aimed at contributing to the process of static reservoir characterization of a carbonated nature. It involved the application and integration of petrophysical solutions, fractal geometry as well as geostatistical concepts which together, allowed the creation of a geological-structural model representative of an area of economic interest for oil and gas industry.
Starting with a set of wells and considering the fundamental structural framework, pseudo-wells of properties (petrophysical solution) were generated between the observed wells, by geostatistical considerations and stochastic simulation, the spatial distribution of petrophysical properties was estimated (∅𝑒, 𝑆𝑤, 𝑉𝑠ℎ) and from this, the hydrocarbon volumetry.
Four exploratory wells were considered within the area of interest and from them, six possible links were established. This finally allowed to generate the spatial distribution of properties (∅𝑒, 𝑆𝑤 and 𝑉𝑠ℎ) and whose correlation establishes that the relatively high magnitudes of ∅𝑒 are related with the structural highs; in addition to that, high magnitudes of
∅𝑒, low magnitudes of 𝑆𝑤 and 𝑉𝑠ℎ, eventually reflect proper conditions of hydrocarbon accumulation.
