In the last years, energy transition from fossil fuels to renewable resources has been largely acknowledged as a necessity to reduce emissions of greenhouse gases in the atmosphere. Hydrogen, the simplest element on Earth, can play an important role in this transition. It is not as an energy source but rather as an energy carrier: in layman’s terms, electricity is converted in chemical energy, which can then be converted again in electricity or in green methane, if combined with carbon...

In the future, we will experience a continuously increasing energy demand mostly due to the continuous growth of the world population. Today we use fossil fuels (coal, oil and gas) in order to cover the society’s basic needs. This involves significant CO2 emissions that contribute to the climate change by contributing to the increase of the global temperature. A great number of countries through international...


Harmonic Pulse Testing was introduced in the early 1970’s as a special case of pulse testing. It is characterized by a periodic variation of production/injection rate. Subsequent developments proved that it could provide the same information as a conventional well test (permeability and skin, heterogeneity) in addition to those given by a pulse test (areal connectivity within the reservoir) if proper...


Pulp and paper mills are characterized by emissions of malodorous gases that commonly create discomfort for people, also in little concentration in the air. This issue is crucial for enterprises that are not actually using the best available technology for reducing non-condensable gases. Thereby, for existing enterprises, it is very important to realize the proper suitable upgrading by choosing the best...


Aerogels are emerging as one of the most intriguing and promising groups of microporous materials, characterized by impressive properties such as low density, high surface area, high porosity and tunable surface chemistry. Fostering unique thermal and acoustic insulation features, for several decades they mainly received attention from the aerospace and building sectors. More recently, new great opportunities...


In mature oilfields, decommissioned oil and gas wells with depths reaching approximately 5000-6000 metres represent good candidate structures for geothermal heat exploitation, as they can provide useful access to subsurface geothermal energy resources. Comprehending the possibility to economically harness geothermal energy by means of coaxial WBHEs is bound to the main features of the physical model,...


This article aims to provide a glance about the current and future applications of Big Data Analytics (BDA) within the Oil&Gas industry, which is searching for an improvement in data managing equal to the improvement in techniques and technologies required by current and future hydrocarbon production. The connection and compatibility of BDA with the hydrocarbon sector is analyzed, highlighting its...


The majority of rural areas in developing countries live in a state of chronic emergency, due for the most part to the lack of sanitary assistance and food. Covid-19 aggravates this situation, complicating the action of International Cooperation in these countries. To this extent, the case study of the Nosy Mitsio island (Madagascar) is presented. The partnership between H4O, Kukula and Politecnico di...


The paper provides an overview of the several scientific and technical issues and challenges to be addressed for underground storage of carbon dioxide, hydrogen and mixtures of hydrogen and natural gas. The experience gained on underground energy systems and materials is complemented by new competences to adequately respond to the new needs raised by transition from fossil fuels to renewables. The experimental...


The aim of this paper is to analyze the factors affecting hydrogen as well as Carbon Capture and Storage Technologies (“CCS”) policies with refer to countries’ upstream capacity of hydrocarbon activities. By using a panel data of 79 countries in 20 years, the interactive model will take into consideration Oil Reserves in relationship with Fossil Fuel Consumption, Blue or Green hydrogen...


The storage of natural gas in underground geological formations (UGS) has been widely adopted to guarantee a real-time response to the market requests as well as to ensure National “strategic” reserves. In the recent past, the UGS and related technologies have been approached with increasing interest also in terms of CO2 sequestration and of large-scale storage of chemical energy, with the...


The objective of this review is to analyse the risks associated with the use of fluids in chainsaws
operations, comparing traditional and eco-friendly materials.
We chose to investigate operations involving the use of portable equipment, particularly those that still use internal combustion engines. Indeed, they pose a high risk to operators due to their proximity to the machine. The scientific literature concerning fuel mixtures and chain oils was studied.
Correlating the examined activities, equipment and machines and their materials,...

This article focuses on the evaluation of the oil and gas potential and the investigation of reservoir properties within the terrigenous horizons of the Middle and Lower Jurassic deposits located in the Kandym uplift of the Bukhara-Khiva region. The assessment methodology presented in this study is based on the analysis of geophysical well logging data curves. The authors conducted an analysis using real...


In this paper, we discuss how to describe the geomechanical behavior of geological formations used for underground fluid storage through the application of the Virtual Element Method (VEM) on conforming polyhedral meshes for the solution of stress-strain equilibrium equations. Under the assumption of small deformations, the solution algorithm for an Isotropic Linear Elastic (ILE) constitutive law coupled...

CiteScore:
2020: 3.8
CiteScore measures the average citations received per peer-reviewed document published in this title.
CiteScore values are based on citation counts in a range of four years (e.g. 2016-2019) to peer-reviewed documents (articles, reviews, conference papers, data papers and book chapters) published in the same four calendar years, divided by the number of these documents in these same four years (e.g. 2016 —19).
Source Normalized Impact per Paper (SNIP):
2019: 1.307
SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SCImago Journal Rank (SJR)
2019: o.657
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal's impact.
Journal Metrics: CiteScore: 1.0 , Source Normalized Impact per Paper (SNIP): 0.381 SCImago Journal Rank (SJR): 0.163
