Abstract

This proposal aims to retrace the efforts of the international community in defining and implementing the “functional education,” allowing women to access the necessary knowledge and competences to stimulate the socioeconomic development, combat the effects of conflicts on their empowerment, and become protagonists of the transition to the digital era. Education and training become the privileged field for international confrontation on gender equality, resulting in a commitment to grant equal opportunities in education and training as an intrinsic right of women. In a diachronic perspective, however, despite the positive afflatus of the first attempts, a substantive approach centred on the individual's capacity to access rights, resources, services and technologies is only later envisaged, which then finds a new definition in the concept of capability approach. UNESCO's dedication to abolish gender discrimination in accessing education in its different grades and fields (adopted as a case-study) makes it apparent that in the colonial and postcolonial era, the commitment of the international community has been directed to sustain equal access for women to all grades and modes of education, within the wider and more complex frame of promoting gender equality and women's empowerment. Today, Eleonor Roosevelt's slogan Making Human Rights Come Alive (Columbia University, 1949) has become one of the guiding principles of the 2030 Agenda and of its development goals. Women must not be left behind: women must be granted equal access to technology education, where they must be able to compete with men for future professions, through policies, strategies, and programmes aiming to reduce/delete digital divide adopted by national governments.

Abstract

Purpose

This study aims to characterize the reservoirs through well log analysis, intensive elastic log studies and cross-plotting (rock physics studies) of the Y-Field reservoirs to define the reservoirs hosting hydrocarbons in the basin with structural complexity. Poor evaluation of sand body has been part of the problem leading to wet wells and these above methods accounted for this gap.

Design/methodology/approach

The basic parameters needed for the characterization are P-wave (Vp), S-wave (Vs) and density (ρ) and understanding the relationship between these parameters with the pore-fluid and lithology is of utmost importance in the evaluation of sand body. This was achieved through elastic rock physics studies. Important among these elastic logs include P-impedance (Zp), S-impedance (Zs), Vp/Vs ratio, Poisson’s ratio, lambda-rho (λρ) and mu-rho (µρ), and are critical. Rock physics diagnosis involving elastic log generation and analysis accompanied by cross-plotting of the elastic logs color-coded with petrophysical properties were employed.

Findings

The findings from the elastic logs indicated that hydrocarbon-charged units are characterized by low Zp, Zs, Vp/Vs ratio, Poisson’s ratio, λρ and µρ resulting from a significant drop in P-wave and density because of hydrocarbon presence. The results also showed that some of the reservoirs with hydrocarbon accumulations exhibit high Vp/Vs and Poisson’s ratio as against their usual low values in hydrocarbon intervals which results from the presence of shale with high plasticity. The elastic logs cross-plots of Vp/Vs with Zp, Poisson’s ratio with Zp and λρ with µρ successfully distinguished between the hydrocarbon-charged zone and the brine-saturated units. All these outcomes are the benefits of this research.

Originality/value

It can be shown that the analysis/results have distinguished hydrocarbon-charged units from brine-saturated intervals and the originality lies in the integration of various sophisticated fluid identification templates.
