“…Figure (1) shows these terms of oil recovery, as defined by the Society of Petroleum Engineers (SPE) [2,3]. Primary and secondary recovery (conventional recovery) targets mobile oil in the reservoir and tertiary or EOR targets immobile oil (that oil which cannot be produced due to capillary and viscous forces).…”

This research aims to study the effect of using alkaline (caustic) and surfactant materials to improve the recovery of Iraqi crude oil under laboratory conditions. Flooding tests were carried out by using solutions of two alkalines (NaOH, Na2CO3) and two anionic surfactants materials were prepared at three concentrations ( 0.5%, 1%, 2 % ) using sand packs with ( 8.5 cm ) length and ( 6.5 cm ) diameter, which is saturated with tap water and then saturated with Basrah crude oil of 40 APIo density and 39.5 cp viscosity. The results were compared with the results of flooding tests by tap water and 2wt% brine water. In tests that tap water and 2wt% brine water were used as a primary recovery a secondary recovery had been tested by using materials that gave highest recovery, the results showed an increase in the recovery and the highest value was 50% by using 0.5% surfactant no.2. The research showed different effects of these solutions. In general, alkalines type showed an increase in recovery factor vs. concentration, but surfactant type showed decrease in the recovery factor vs. concentration. Also, the results showed that the recovery by using surfactant no.2 were the best respective to other materials, and the highest recovery obtained was 90.9 at 0.5%.

“…Enhanced Oil Recovery (EOR) or tertiary recovery is has been applied to achieve higher oil recovery from a reservoir that could not be produced by primary and secondary recoveries [28]. According to Collins (1977), EOR is the incremental production of oil with the introduction of artificial energy into the reservoir and can be divided into three major categories that are thermal EOR, chemical EOR and miscible EOR [29].…”

Measurement of Streaming Potential in Downhole Application: An Insight for Enhanced Oil Recovery Monitoring

et al. 2016

Abstract. Downhole monitoring using streaming potential measurement has been developing in order to respond to actual reservoir condition. Most studies have emphasized on monitoring water flooding at various reservoir condition and improving the approaches of measurement. Enhanced Oil Recovery (EOR) could significantly improve oil recovery and the efficiency of the process should be well-monitored. Alkaline-surfactant-polymer (ASP) flooding is the most promising chemical EOR method due to its synergy of alkaline, surfactant and polymer, which could enhance the extraction of residual oil. However, limited studies have been focused on the application of streaming potential in EOR processes, particularly ASP. Thus, this paper aims to review the streaming potential measurement in downhole monitoring with an insight for EOR application and propose the potential measurement in monitoring ASP flooding. It is important for a preliminary study to investigate the synergy in ASP and the effects on oil recovery. The behaviour of streaming potential should be investigated when the environment of porous media changes with respect to ASP flooding. Numerical model can be generated from the experimental data to forecast the measured streaming potential signal during production associated with ASP flooding. Based on the streaming potential behaviour on foam assisted water alternate gas (FAWAG) and water alternate gas (WAG) processes, it is expected that the streaming potential could change significantly when ASP flooding alters the environment and surface properties of porous media. The findings could provide new prospect and knowledge in the relationship between streaming potential and ASP mechanisms, which could be a potential approach in monitoring the efficiency of the process.

Exploration and Production of Petroleum and Natural Gas

The energy industry played an important role in shaping the 20th century and remains a major force driving economic development well into the 21st century. Hydrocarbons are an important commodity rather than being a luxury in our lives. Recently published data indicate that roughly 55–60 % of the world's energy demand is met by oil and natural gas resources. Serious concerns remain, however, that an increase in production cannot really cope with the increase in the global demand, at least at the current cost and price range. Those trends force energy companies to search for hydrocarbon resources in deeper and tighter formations, such as arctic and deepwater, and to look for opportunities for extracting hydrocarbon resources from extremely tight formations, such as shales, which would have been hard to imagine a decade ago. In addition, a significant number of oil companies at all sizes are now looking into enhanced oil recovery (EOR) deployment opportunities in different parts of the world. Significant growth in global energy demand and technical challenges associated with extracting hydrocarbons from deeper and tighter formations as well as the cost intensity of the EOR projects will force the oil industry to become more technology and innovation oriented in the next few decades. Regrettably, oil is a nonrenewable energy source and finite. Technically and economically feasible oil will inevitably run out. The current debate is how much longer these fossil fuels will continue to be the dominant energy source of the world.
