Unconventional natural gas resources are very important for ensuring energy security. It is a concern that conventional natural gas resources will be unable to meet growing supply requirements. This concern has prompted a scramble to secure long-term natural gas supplies. In a high oil and gas price environment, unconventional resources are viewed as important and economically attractive components of future natural gas supplies. Shale gas is natural gas produced from shale formations. Gas shales are organic-rich shale formations. Shale gas is a dry gas composed of methane. Various factors which have contributed to its rapid development are mainly advancements in horizontal drilling, hydraulic fracturing, and, perhaps most importantly, the rapid increase in natural gas prices in the last several years as a result of significant variation in supply and demand. India has a high potential for shale reserves. According to the available data, a comprehensive shale gas pilot project carried out in the Damodar Valley Basin has made an initial gasin- place estimate of 300 to 2,100 trillion cubic feet (TCF) in Indian shale gas basins, which is around 300 times higher than the Krishna Godavari Dhirubhai 6 (KG-D6) basin, by far the largest gas field in the country. In this paper, a brief review of shale gas reserves across the world and their government policies has been explained.
The main objectives of oil-well cementing are to restrict the movement of fluids from one zone to another and to provide a stable position for the casing string. Achieving greater compressive strength, tensile strength, and lower permeability are the main features for increasing the effectiveness of cement jobs. The conventional cementing job lacks the ability to attain these properties even with the usage of advanced materials like self-healing agents, fibers, and polymeric materials in cement slurry. However, a scope of improvement is required in providing better zonal isolation. According to studies, the inclusion of nanoparticles would improve cement efficiency by achieving sufficient compressive strength and durability, reducing potential maintenance costs and environmental effects. With the addition of nanoparticles to cement, slurry increases compressive strength, decreases settling time, and increases density by reducing the porosity and permeability of the cement sheath. This study provides an explanation of the alterations in oil-well cement properties with the addition of nanaparticles at different temperatures and incubation periods.
The freshwater availability in many regions of the world has been a rising concern for the last few decades due to disturbing increase in population, urbanization, and industrial advancement. As water consumption is increasing year by year, the obvious solution to the freshwater shortage is to increase its supply. Desalination has been a prominent process to produce fresh water in numerous water-stressed regions to counteract the water shortage issues. Amongst the various desalination methods, the reverse osmosis method is used for generating fresh water from saline or brackish water by removing salts to make it suitable for human utilization, agriculture, and industrial purposes. In the present study, a systematic review of the seawater reverse osmosis process is presented to address the developments in the pretreatment, membrane, and post-treatment processes of reverse osmosis.
To prevent pollution of air, water, and land resources as well as the transfer of dangerous chemicals, waste must be seen as a potential resource, rather than something undesired and unwanted. The pace of trash production rises in tandem with population growth and industrialization. Mismanagement of municipal solid waste (MSW) has negative environmental consequences, puts public health at risk, and raises a number of other socioeconomic problems worth addressing. A well-thought-out decision-making policy will significantly enhance the quality of the municipal solid waste management (MSWM) process. We require well-planned and well-designed municipal waste management systems to correctly anticipate the MSWM system. Many urban and rural regions in India have long struggled with waste management issues. People in rural regions let garbage decay and use it as fertilizer on their agricultural fields. As technology advances, different methods are being used to turn trash into energy. This article focuses on the need for trash to be converted into energy as well as other current techniques.
Gas-to-Liquid (GTL) technology has developed over the past few decades into a financially sound industry offering market diversification to remote natural gas resource stakeholders. Presently, several patented technologies are available for the petroleum industries to transport natural gas cheaply in liquefied form. In the recent past, low natural gas prices in North America can be attributed to the isolation of shale gas resources using GTL technology. Some small technology providers are currently using GTL to eliminate associated gas flaring in remote oil fields. Several smaller technology providers are now looking to GTL to stop associated gas flaring in remote producing fields. In addition, GTL has the potential to extract liquid fuel in gas-rich inland areas. The GTL technology is preferred as the existing technologies that process natural gas through olefins are more complex and have so far proven difficult and costly in terms of commercial viability. The various GTL technologies having prospective market scope are reviewed this article.
Modern civilization requires comforts in lieu of environmental destructions specially due to urbanization. About 30% population of the country live in crowded and densely populated cities. It is due to more employment opportunities, educational, medicare and infrastructural facilities. Population densities, vehicle population, cutting of trees, solid waste coming out from housing units, water quality and so many other reasons have the impact for pollution in cities. The quality of life appears to be more strenuous and stressful. A case study on Bhubaneswar municipal corporation limits has been conducted and suggestions for improvement are given to avoid the catastrophe of environmental degradation.
