3- CHEMICAL ADSORPTION IN ENHANCED OIL RECOVERY.
George Emad & Prof. Attia Attia (Supervisor)
One of the main setbacks of chemical injection technique is the chemical adsorption on the rock surface as it affects the reservoir permeability and may cause reduction in recovery as well as affecting the project economics as a large amount of chemical is lost into the formation. Thus, the chemical adsorption is the main controlling factor of the enhanced oil recovery project success or failure. The objective of this research is to investigate the factors affecting the rheology of Xanthan gum polymer and Sodium dodycyl benzene sulphonate surfactant, establish a new correlation to predict the amount of polymer and surfactant adsorption in the reservoir based on the initial chemical concentration, and finally to study the factors affecting the chemical adsorption as salinity, concentration, nano-Silica addition, and rheology in order to control these factors to minimize the chemical adsorption. The results showed that by relating the amount of adsorption obtained experimentally and the initial chemical concentration, a new empirical correlation was developed. The amount of chemical adsorption can be minimized by decreasing the solution salinity, decreasing the chemical concentration, and in case of nano-Silica application, the nano-Silica concentration should be low to avoid high adsorption, finally the amount of polymer adsorption in the limestone formation was significant, while the amount of surfactant adsorption on limestone was lower, thus the surfactant flooding appears to be more promising for application in limestone formation, however further research is required to determine the economic and technically viability of the project.
 
The aim of this module is to provide necessary mathematical foundation in probability and statistics for engineers.
 
Petroleum Engineering and Gas Technology Department, PEGT, is dedicated to provide a high graduated engineers to local and national oil and gas companies. The undergraduate programme in PEGT is a four-year program, in addition to prep year. We conduct excellence and high quality in teaching and research and provide students with the necessary knowledge in exploration, drilling, production, reservoir engineering, oil and natural gas production to ensure that they achieve the highest possible success in their future professional careers, to meet national and international challenges.
Those who complete this program are entitled as Petroleum and Natural Gas Engineers. PEGT offer its students a unique blend of theoretical and practical oil and gas applications depicted in its various laboratories such as; Reservoir Rock, to produce SCAL report; Reservoir Fluid, to produce PVT report; Geological, Surveying; and Drilling Fluid. In addition, the department striving all efforts to make its software laboratories up-to-date such as; Reservoir Simulation, Oil and Gas processing, and Well Test. All the laboratories fulfill the health and safety requirements.
 
Petroleum engineering is Science, Technology, Engineering, and mathematics. It could also be under Agriculture, Food, and Natural Resources because you dig oil from the ground. To be a petroleum engineer is a choice you should take by your own, it exposes you to different conditions that could be harsh for you to live with. However, it allows you to interact with different cultures as you will be able to travel around the world searching for the oil & gas. Petroleum Engineers must be able to communicate because they have to write draft proposals, and writing reports and you have to work in a team of people. Moreover, petroleum engineers earn lots of money and gain a lot of experience. There are very few petroleum engineers left as more retire and not as many graduate. Big oil companies are looking for more of them so I think it would be a great career.
