Simulation Study of Hot Waterflood and WASP Injection Post Mature Steamflood

Abstract

<em>Steamflood is the most successful thermal EOR applied throughout the world and have produced the biggest portion of oil from EOR methods. As high intensity energy and associated cost are put to produce oil, optimization in any level can have tremendous impacts. Optimization in steamflood operation can be achieved by optimizing steam injection (rate, time), especially in mature pattern/ field or nearing the end of field life/ abandonment. This objective can be done thru utilization of retained heat in the reservoir and overburden/ underburden as they are not instantaneously produced with fluids. By using reservoir simulation, it can be shown that injection is not necessary to be continue until abandonment but can be stopped at a much earlier time hence a much profitable steamflood operation can be achieved.</em>

Laboratory Study of Enhanced Oil Recovery with Used Palm Oil Surfactant Injection

“…Tertiary recovery is commonly called enhanced oil recovery (EOR) which is an advanced technique for removing oil if various basic techniques have been carried out but the results are not as expected or are not economical [7]. EOR methods are constantly evolving such as thermal injection, gas injection, chemical injection and microbial injection [8][9][10][11][12][13][14]. Of the many EOR methods, not all of them can be used for a reservoir, because each reservoir has different characteristics.…”

Steam-Propane Injection Simulation for Heavy Oil

“…As a result, the team is utilized to heat the reservoir and lower the oil viscosity. Steam is converted to hot water once it has been transferred, which improves the sweep efficiency and allows more oil to be produced [1][2][3][4].…”
