Enhanced Oil Recovery (EOR) EOR increases oil recovery rates significantly, extending the productive life of reservoirs, and it enables recovery of oil from mature fields that have undergone primary and secondary recovery. EOR techniques are broadly classified into three main categories: Thermal Recovery Thermal Recovery involves the application of heat to reduce the viscosity of heavy oil, making it easier to flow. Steam is injected into the reservoir to heat the oil. The method commonly used in heavy oil and bitumen reservoirs. Gas Injection Gas Injection involves the injection of gases to either miscibly or immiscibly interact with the oil, improving its mobility. It includes carbon dioxide (CO₂) injection : CO₂ mixes with the oil to reduce viscosity and swell the oil, helping it flow to production wells. Hydrocarbon gas injection : Lighter hydrocarbons are injected to mix with reservoir oil. Nitrogen injection : Primarily used to maintain pressure or in miscible displacement. The method is effective in light and medium oil reservoirs. Chemical Injection Chemicals are injected to improve oil displacement efficiency. It includes polymer Flooding : Polymers increase water viscosity, improving the sweep efficiency. Surfactant-Polymer Flooding : Surfactants reduce oil-water interfacial tension, aiding oil mobilization. Alkaline Flooding : Alkaline solutions react with certain crude oils to form surfactants in-situ. The method is applied in reservoirs with favorable chemical interactions Challenges of EOR High cost of implementation and operation. Requires advanced technology and infrastructure. Environmental concerns, including risks of water contamination and CO₂ handling. Reservoir-specific constraints, such as temperature, pressure, and oil properties. The integration of EOR with geomechanics involves understanding and managing the mechanical behavior of the reservoir and surrounding rocks during EOR processes. Geomechanical Considerations in EOR Reservoir Stress Changes : Fluid Injection : Techniques like steam, CO₂, or chemical injection increase pore pressure, altering the effective stress in the reservoir and potentially inducing deformation. Stress Redistribution : Changes in stress may cause fractures, faults activation, or compaction. Rock-Fluid Interactions : Thermal Expansion : In thermal EOR, injected heat causes thermal expansion of the rock matrix, affecting stress and permeability. Chemical Reactions : Chemicals can alter rock integrity through mineral dissolution or precipitation. CO₂-Induced Changes : CO₂ injection can lead to chemical interactions with carbonate rocks, weakening the formation. Reservoir Deformation : Compaction : High-pressure EOR methods can lead to reservoir compaction, impacting porosity and permeability. Subsidence : Surface subsidence can result from reservoir compaction, especially in unconsolidated formations. Fracture Dynamics : Geomechanics determines whether induced fractures propagate or stay controlled. Caprock Integrity : Maintaining the seal's integrity is critical to preventing leakage during CO₂ or fluid injection. Fault Reactivation : Pressure changes may reactivate existing faults, potentially leading to seismic events or reservoir compartmentalization. EOR plays a crucial role in meeting global energy demand while also addressing environmental sustainability challenges. Integrating geomechanics with EOR ensures enhanced recovery while minimizing risks, making it an essential aspect of modern reservoir management. Therefore, one of the main topics of the first international conference on geoenergy and the fifth national petroleum geomechanics conference is enhanced oil recovery. Researchers are invited to send their articles in these fields to the first international geoenergy conference and the fifth petroleum geomechanics conference. Conference Registration

Geothermal Energy Geothermal energy is a sustainable and renewable energy source that is obtained from the internal heat of the Earth which reduces dependence on fossil fuels. This energy can be extracted through underground reservoirs of hot water, steam, or hot rocks. In specific areas of the Earth's crust where the subsurface temperatures are notably high (such as points near tectonic plates boundarie or volcanoes), the potential for extracting this energy is significantly greater. This energy has many applications today, including: Electricity Generation: Geothermal power plants use steam from reservoirs to drive turbines connected to electricity generators. Heating and Cooling: Exchange heat between buildings and the ground, offering efficient climate control. Agriculture and Greenhouses: Geothermal hot water is employed for maintaining optimal temperatures in greenhouses, fostering plant growth and increasing agricultural yield. Industrial Uses: Provides heat for processes like drying products, saltwater desalination, and mineral extraction. Tourism and Health: Natural hot springs serve as recreational and therapeutic sites. The development of geothermal systems integrates geological sciences and engineering expertise. Key considerations include: Reservoir Exploration and Modeling : Understanding geothermal reservoirs’ temperature, permeability, and rock properties through geological and geophysical studies. Drilling Challenges : High-temperature environments and fractured rocks present significant operational challenges in geothermal energy extraction. Environmental Impacts : Risks of induced seismicity from fluid injection and ground subsidence from water withdrawal must be mitigated through careful monitoring and management. Economic Viability : Initial exploration and drilling costs are high, though long-term operational costs are low. Therefore, one of the main topics of the first international conference on geoenergy and the fifth national petroleum geomechanics conference is geothermal energy.

Underground storage of carbon dioxide and natural gas One of the conference's main topics is the underground storage of gases, including carbon dioxide. Carbon dioxide, as a greenhouse gas, causes the warming of the earth's atmosphere, one of the solutions to solve this problem is to absorb CO2 and turn it into a liquid at a specific temperature and pressure and inject it into underground reservoirs inside the formations within geological formations with appropriate porosity and impermeable layers around it. Depleted oil and gas reserves can be used for this purpose. Today, natural gas is also stored underground. The underground storage of natural gas basically balances the gas flow in the pipeline network during different seasons. In fact, during periods of low demand, gas is injected into the ground, and during periods of peak demand, gas is withdrawn and consumed. As a result, daily and seasonal demand fluctuations are well managed, and the supply of gas will be proportional to the demand. Compressed natural gas is usually stored in depleted oil and natural gas reservoirs, underground aquifers, and salt dome formations. One of the main topics of the first international conference on geoenergy and the fifth national petroleum geomechanics conference is the underground storage of carbon dioxide and natural gas. Researchers are invited to send their articles in these fields to the first international geoenergy conference and the fifth petroleum geomechanics conference. Conference registration
