Geothermal energy comes from the heat of the Earth's interior. Reservoirs of steam or hot water with temperatures between 225 -600 F can generate electricity, while lower-temperature geothermal fluids are often used directly for heating, agriculture, and industry.[1] In western states like California and Nevada, magma beneath the Earth's surface creates shallow hot water reservoirs. Scientists are developing enhanced geothermal systems to extract heat from hot, dry rocks in order to produce electricity. In 2013, only 0.4% of U.S. electricity came from geothermal, but the U.S. Geological Survey estimates that geothermal energy could power more than 10% of the nation's electricity.[2][3]

Abstract Geothermal energy currently occupies an insignificant role in the renewable energy balance. This is explained by its low heat flow rate and the significant investments associated with heat mining. However, the geothermal heat flow is continuous and non-interruptible and occurs everywhere in the lithosphere. Existing oil and gas fields’ subsurface and surface infrastructure and expertise can significantly decrease capital expenditures for geothermal heat extraction. Taking this idea as a basis, the study of geothermal heat production from existing oil and gas fields of the pre-Caspian region of Kazakhstan was performed. Since this work is one of the first attempts to estimate the geothermal heat potential of the existing oil and gas industry infrastructure in Kazakhstan, the study consists of two big parts. First part is the detailed theoretical review of the geothermal heat extraction methods which may be potentially applied in Kazakhstan. Special attention in the literature review section was given to enhanced geothermal systems and closed loop systems, because they have many technologies in common with the oil and gas industry (completion concepts, hydraulic fracturing etc.). Second part is the quantitative estimation of the geothermal potential based on twenty oil fields, with several wells in each field as trial sites. Quantitative estimation considers pragmatic and optimistic scenario of future investments. The study showed that even in the pragmatic scenario in which the water-producing wells are turned into hydrothermal producers, the recoverable effective heat reaches 420 TJ in total for all wells in the selected fields. However, the demand for the geothermal heating of the industrial and household objects near the selected fields was estimated to be three times higher. Thus, a more proactive geothermal strategy was considered. This strategy yields ~9800 TJ of recoverable effective heat, which covers the demand and provides excess for the growth. Based on the reservoir properties and economic perspective estimations, it was defined that enhanced geothermal systems and closed loop systems will be less abundant in the given region in a short term. However, with development of the geothermal technologies and increase of investments, these systems may have increased importance. On the other hand, direct hydrothermal producers and well doublets (injector connected to producer through the permeable reservoir), most probably, will be a prevailing method of the geothermal heat mining in the pre-Caspian region of Kazakhstan in the short and medium terms.

Exploiting the potential of sunlight, wind, and water not only provides a clean substitute for conventional energy but also unlocks opportunities for innovative technologies and methodologies. It becomes clear that the route to a more environmentally friendly future necessitates a shared commitment to adopting and progressing renewable energy solutions. Through ongoing research, advancements in technology, and widespread implementation, it is time to mark a transformative period for a cleaner and more environmentally conscious world.

Abstract Energy is one of the major components for defining the overall development of a country. Mankind utilizes energy to meet the requirements of daily processes. This energy can be extracted from the renewable as well as the non-renewable sources of energy. With global rise in the usage of non-renewable energy sources, there is a much concern for the green house gas emissions and climate change. Renewable sources of energy are therefore being exploited to reduce the consumption of conventional fuels and overall reduce the environmental impacts. While solar, wind and tidal energy have been in scope of research, geothermal reservoirs are also proving their potential as a renewable source of energy. Geothermal reservoirs are one of the cleanest and renewable sources of energy which can meet the rising global energy crisis. Proper exploration and exploitation of geothermal energy is therefore one of the key objectives of reservoir engineers to adopt this energy source. The challenge which lies is to find best fit analytical methods for pressure transient analysis of geothermal reservoirs. This is because the assumptions made to predict the pressure transient analysis in hydrocarbon reservoirs are not satisfied by geothermal reservoirs. Based on extended studies it has been assumed to choose the properties of injected fluid in the reservoir conditions. But the gap between the reality and prediction couldn't be minimized as the properties of the hot and cold fluid in the reservoir conditions vary non-uniformly with respect to time. In this paper the impact of cold water injection on pressure transient analysis of geothermal reservoir is studied by varying the temperature of the injectate cold water from room temperature to reservoir temperature.

Tectonic plates are massive rigid pieces of the Earth's crust which form the majority of the geological foundation of the Earth. These plates slowly move across the Earth, moving entire sections of continental and oceanic crust along with them. The boundaries between the plates are areas where significant earthquakes and volcanic activity occur. It was only accepted into the scientific community in the late 1900's. The possibility of continental movement was first suggested in the late 1600's, but it was not accepted as a scientific hypothesis until 1912, when German meteorologist Alfred Wegener published articles describing his idea of continental drift.

From 26 August-2 September 1992, about 100 geophysicists met in Wellington, New Zealand to discuss advances in electromagnetic methods. The workshop was organized by the International Association of Geomagnetism and Aeronomy Working Group I-2 under the auspices of the International Union of Geodesy and Geophysics. The working group specializes in electromagnetic induction in the earth and deals mainly with crustal investigations. It meets every other year at various geographic locations to discuss the advances in electromagnetics from the theoretical as well as the practical side.
