Vietnam plans to develop dozens of new coal-fired power generation units over the next 20 years. In order to reduce emissions, it may appear necessary to dispose of these plants' CO2 by burying it in deep underground geological formations instead of releasing it into the atmosphere, using Carbon Capture and Storage (CCS) technology. We show that CCS has a technical potential in Vietnam. To disc...

The application of nanoparticles for enhanced oil recovery (EOR) has been shown to be advantageous over conventional methods. Wettability alteration reservoir rock from oil-wet water-wet is one the main factors in improving matured reservoirs. sandstone reservoirs are generally negatively charged, and hence, a proper selection surface charge important. In this work, novel nanofluid prepared usi...

Production of mature oil fields emits significant amount CO2 related to circulation and handling large volumes gas water. This can be reduced either by (1) using a low-carbon energy source and/or (2) reducing the non-hydrocarbon produced/injected fluids. paper describes how improved recovery techniques designed reduce intensity (kgCO2/bbl oil) production efficient use injectants. It is shown th...

The recovery factor in unconventional reservoirs is typically 5–10%, with extensive hydraulic fracturing and infill drilling to maintain the production rate. Concurrently, rush towards decarbonization opening up new possibilities for CO2 utilization, enhanced oil (EOR) being one example. CO2-EOR presents an opportunity both financial gain through improved factors, as well reducing carbon footpr...

Fracture reservoirs contain most of the oil reserves of the Middle East. Such reservoirs are poorly understood and recovery from fractured reservoirs is typically lower than those from conventional reservoirs. Many efforts have been made to enhance the recovery and production potential of these reservoirs. Fractured reservoirs with high matrix porosity and low matrix permeability need a seconda...

Unconventional oils mainly heavy oils, extra heavy oils and bitumens represent a significant share of the total oil world reserves. Oil companies have expressed interest in unconventional oil as alternative resources for the energy supply. These resources are composed usually of viscous oils and, for this reason, their use requires additional efforts to guarantee the viability of the oil recove...

Carbon dioxide has been used commercially to recover oil from reservoir by enhanced oil recovery technologies for over 40 years. Currently, the CO2 flood is the second most applied enhanced oil recovery (EOR) processes in the world behind steam flood. Water alternating gas (WAG) injection has been a popular method to control mobility and improve volumetric sweep efficiency for CO2 flooding. The...

The biosurfactant production by Bacillus licheniformis W16 and evaluation of biosurfactant based enhanced oil recovery (EOR) using core-flood under reservoir conditions were investigated. Previously reported nine different production media were screened for biosurfactant production, and two were further optimized with different carbon sources (glucose, sucrose, starch, cane molasses, or date mo...
