... requirements. A lot of research is happening to exploit this promising energy source. Geothermal energy is extracted by injecting a fluid stream and the fluid coming out of the reservoir is then used to run turbines to meet the power requirements. This paper highlights the study on the pressure transient...

.... The objectives were to validate the laboratory results, assess the critical chemical process parameters such as Sor reduction, adsorption, injectivity, and obtain an operating experience at a harsh offshore environment with high reservoir temperature. Sea water treatment and softening process was needed...

...Bottom Aquifer For reservoir with strong bottom aquifer, it is essential to make a balance between favorable production rate and water influx rate targeting better economic results and recovery factor. And it is usual for sacrifice production rate for economic factors. For reservoir B...

... Abstract Characterizing an oil reservoir requires one to understand the Pressure- Volume-Temperature (PVT) properties of reservoir fluids, especially bubble point pressure, solution gas oil ratio and oil formation volume factor because of its more often utilization in reservoir engineering...

... geomechanical work suggests that undeformed rock samples will break during injection, it is likely that natural fractures, present as initial weaknesses in the reservoir, may have been further enhanced during injection. Initial natural fractures are likely present within the cemented cycle tops as well...

.... Recent pressure surveys show that the average reservoir pressure has increased to about 2600 psi. Understanding aquifer behaviors has been modeled extensively in the industry using various analytical models ( Marques, 2007 ). According to ( Omeke, J. E., et al, 2011 ), application of these models...

... theories and experimentation between permeability to gas and permeability to a liquid is: Abstract The importance of permeability cannot be under-stimated. It is used in crucial equations used to determine quantities analysed by reservoir, drilling, and production engineers. Using permeability along...

... While the pore-scale ranking looks at recovery improvement, compatibility instead looks at potential show-stoppers due to each EOR method's current reservoir conditions. In this section, issues such as chemical compatibility with formation temperature, salinity, and injectivity (directly related...

... can support asset teams in this complex decision-making process. Optimization of real-life field development cases can be computationally very demanding due to the cost of running large amounts of large-scale reservoir simulations, the large number of variables to be optimized and the necessity...

... This equation governing the flow of a fluid in a reservoir results from a combination of Darcy's law and the conservation of mass equation for that phase. Running the numerically expensive simulation to solve the above equations is also challenging. This is because (1) reservoirs are huge...
