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...
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...
