Coal is mined in every country which is mainly used to generate electricity. Thousands of mine workers were killed every year due to many disasters takes place inside coal mine. These accidents are caused mainly due to the leakage of poisonous gas [2] present in the mine. Especially developing countries face a poor safety system for mine workers. Hence it requires a safety monitoring system [1]...

Underground storage of carbon dioxide (CO2) in geological formations plays a vital role capture and (CCS) technology. It involves capturing CO2 emissions from industrial processes power generation storing them underground, thereby reducing greenhouse gas curbing the impact climate change. This review paper features comparative analysis deep saline aquifers, depleted reservoirs, coal seams, basa...

Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' safety. The purpose of this work is to provide the prediction maps for the C1, C2, and B2...

There is a relationship between the economic requirements for development of oil and gas facilities in oil-producing regions North environmental problems sustainable development. One ways to solve this problem wider use underground storage both reducing peak loads Unified Gas Supply System by collecting storing previously flared associated petroleum gas, burying large volume industrial emission...

The 21st Century industrial civilization that surrounds us is profoundly dependent upon massive energy storage so familiar that even the authors of this Special Issue seldom notice it. Seemingly unrelated to mankind’s shrinking primary dowries of fissile or fertile nuclides and of fossil organic carbon, are the commonplace and unremarked piles powdered coal outside electric generating stations,...

Among the options being considered to help mitigate anthropogenic CO2 emissions is carbon sequestration in depleted oil or gas wells, coal seams, and deep underground saline formations. One of the uncertainties that must be addressed with respect to geologic sequestration is the long-term risk associated with storage of large quantities of CO2 in the subsurface. Rapid release of CO2 could occur...

Methyl-tert-butyl ether (MTBE) is a commonly used gasoline additive. Leaking underground storage tank systems, spills, and pipeline failures are the causes of reported groundwater contamination with MTBE. The impact of vegetation on MTBE plume transport in groundwater and volatilization was experimentally examined. The experimental system consists of six channels, five of which are planted with...

One of the major challenges in petroleum industry is producing residual oil from underground. One of the major techniques for enhancing oil recovery (EOR) is using gas injection. However, gas has poor volumetric sweep efficiency, this is attributed to its high mobility which considers to be higher compared with oil and water mobility. Several techniques are proposed and applied for reducing gas...
