This book describes the geothermal potentials of some hydrocarbon reservoirs. It explains the design differences of hydrocarbon and geothermal wells and the different stimulation methods used in hydrocarbon and geothermal exploitation. The methods of heat extraction and electric energy generation from abandoned hydrocarbon wells are described as well as mechanisms to increase permeability and porosity if the corresponding natural values are too low. The book discusses the different scenarios how geothermal energy of hydrocarbon reservoirs can be used: (1) In wells with ongoing oil and gas exploitation where co-produced hot water can be used to generate in abandoned oil and gas wells that can become a source for commercial geothermal electricity production and a huge commercial opportunity; (2) in offshore applications helping to solve the problems of disposal of oil platforms, and using them for extraction of geothermal energy; (3) drilling new geothermal wells in promising hydrocarbon reservoirs where there is detailed subsurface data available from the oil and gas drillings. All these options are discussed in the context of geological setting, technical demands and feasibility, scale, costs, etc.sustainable option for clean water production from seawater and from highly mineralized or otherwise unsuitable ground- and surface water. The book provides an overview on possible cost-efficient techniques and application opportunities for different scales and shows why the implementation of these technologies faces numerous technological, economic and policy barriers and gives suggestions how these hurdles can be overcome. Costs of novel treatment units using renewable energy sources are discussed and compared with those of other technologies for clean water production considering external costs, such as environmental and social costs which are caused by using fossil fuel based technologies. Energy efficiency is highlighted since it is of special importance in systems that are to be powered by renewable energy. Moreover applications of water supply systems providing water in emergency condition are discussed.
The book provides a journey through recent technological developments to harvest energy from abandoned geothermal wells and allows the reader to view the process from a thermodynamic and numerical modeling perspective.

Previously conducted preliminary investigations within the deep Delaware and Val Verde sub-basins of the Permian Basin complex documented bottom hole temperatures from oil and gas wells that reach the 120-180C temperature range, and occasionally beyond. With large abundances of subsurface brine water, and known porosity and permeability, the deep carbonate strata of the region possess a good potential for future geothermal power development. This work was designed as a 3-year project to investigate a new, undeveloped geographic region for establishing geothermal energy production focused on electric power generation. Identifying optimum geologic and geographic sites for converting depleted deep gas wells and fields within a carbonate environment into geothermal energy extraction wells was part of the project goals. The importance of this work was to affect the three factors limiting the expansion of geothermal development: distribution, field size and accompanying resource availability, and cost. Historically, power production from geothermal energy has been relegated to shallow heat plumes near active volcanic or geyser activity, or in areas where volcanic rocks still retain heat from their formation. Thus geothermal development is spatially variable and site specific. Additionally, existing geothermal fields are only a few 10's of square km in size, controlled by the extent of the heat plume and the availability of water for heat movement. This plume radiates heat both vertically as well as laterally into the enclosing country rock. Heat withdrawal at too rapid a rate eventually results in a decrease in electrical power generation as the thermal energy is "mined". The depletion rate of subsurface heat directly controls the lifetime of geothermal energy production. Finally, the cost of developing deep (greater than 4 km) reservoirs of geothermal energy is perceived as being too costly to justify corporate investment. Thus further development opportunities for geothermal resources have been hindered. To increase the effective regional implementation of geothermal resources as an energy source for power production requires meeting several objectives. These include: 1) Expand (oil and gas as well as geothermal) industry awareness of an untapped source of geothermal energy within deep permeable strata of sedimentary basins;2) Identify and target specific geographic areas within sedimentary basins where deeper heat sources can be developed;3) Increase future geothermal field size from 10 km2 to many 100's km2 or greater; and4) Increase the productive depth range for economic geothermal energy extraction below the current 4 km limit by converting deep depleted and abandoned gas wells and fields into geothermal energy extraction wells. The first year of the proposed 3-year resource assessment covered an eight county region within the Delaware and Val Verde Basins of West Texas. This project has developed databases in Excel spreadsheet form that list over 8,000 temperature-depth recordings. These recordings come from header information listed on electric well logs recordings from various shallow to deep wells that were drilled for oil and gas exploration and production. The temperature-depth data is uncorrected and thus provides the lower temperature that is be expected to be encountered within the formation associated with the temperature-depth recording. Numerous graphs were developed from the data, all of which suggest that a log-normal solution for the thermal gradient is more descriptive of the data than a linear solution. A discussion of these plots and equations are presented within the narrative. Data was acquired that enable the determination of brine salinity versus brine density with the Permian Basin. A discussion on possible limestone and dolostone thermal conductivity parameters is presented with the purpose of assisting in determining heat flow and reservoir heat content for energy extraction. Subsurface maps of temperature either at a constant depth or within a target geothermal reservoir are discussed, but have yet to be completed.

The increasing consumption of energy and its side-effects on the environment are driving an international effort to enhance the use of more environmentally-friendly energy resources such as geothermal energy which this research addresses. The work has involved an analysis of data provided by the B.C. Ministry of Energy, Mines and Petroleum Resources collected from oil and gas wells drilled in the Northeast region of British Columbia for the purpose of evaluating the potential to exploit geothermal energy in the region. The study area was narrowed to two gas fields near Fort Nelson - Clarke Lake and Milo. The objectives of the project have been 1. to investigate the geothermal potential of the area; and, 2. to examine if non-geothermal wells could be used to recover geothermal energy; Using data gathered from the gas well log records, temperature gradient and heat flow maps were successfully generated for the study area using ArcGIS. A preliminary reservoir assessment has been done based on these maps. The results show the region has notably high potential for a deep geothermal project using Enhanced Geothermal System (EGS) methodologies to produce significant amounts of electrical energy for a very long time in a sustainable fashion. It is recommended that additional exploration and exploitation drilling should be done at Clarke Lake to verify the conclusions and strengthen the assumptions about suitable local rock permeability and fluid availability at depth. With respect to geothermal energy production from spent oil and gas wells, there is currently insufficient temperature and fluid flow to either recover heat for a district heating system in the nearby community of Fort Nelson or to generate electricity using a Binary Cycle process. The quantity of heat is too low to be an economically viable investment while the temperature is too low at the current gas plants to technically generate power. The research has demonstrated that data from drilled oil and gas wells.

This book explores the different aspects of energy in human life especially expressing the advanced technologies in renewable energy resources. Due to the environmental pollution caused by fossil fuels and the non-permanent nature of these resources, the move towards the use of renewable energy has accelerated. In recent years, many attempts have been made to improve energy systems' performance by using multi-generation units, and these set-ups have been analyzed from the perspective of energy, exergy, economics, and environmental indicators. The book's primary goal is the effort to introduce new methods for assessing and upgrading the synergy. Therefore it examines sustainable practices such as water-energy-food nexus in poly-generation units, novel desalination systems, and smart greenhouses. One of the significant issues in these energy systems is the storage methods; for instance, carbon capture to reduce environmental pollution and the hydrogen store for the utilization in supplementary fuel. Also, robust optimization, uncertainty and risk-aware probabilistic analysis, energy management, and power supply of sensitive places such as oil rig platforms by renewables are examined.
