Abstract
With the worldwide production of hydrocarbon, an increasing challenging problem is how to get high oil recovery from the reservoir rather than drill more wells. Water flooding is the most significant way in secondary oil recovery by injecting water into the certain formation to displace oil. This experiment is a simulated situation to displace oil from ideally 100% oil saturation sand formation with water flooding. Usually the problem associated this technique is inefficient recovery due to variable permeability. Thus, we inject a certain amount of gel, after sufficient water injection until little oil could be swept anymore, to block the high permeable zone. As the pathway where water used more likely to go through is blocked, we could continue another set of experiment of water injection to displace the oil in low permeable zone. This experiment is focusing on how gel could affect the oil recovery during water flooding.
Biography
Yiwen Gong majors in Petroleum Engineering, Missouri University of Science and Technology. She has the Internship experiences at Halliburton (completion and management system) and simulation study in Antonoil. She has learned the water flooding methods to approach the oil recoveries from unconsolidated sands with varies water injection rates. And she has analyzed the gel plugging effect for water flooding at low permeable zone. She applied the secondary recovery knowledge to the experiments and arrived at the reasonable results.
