The Laboratory Test of AOS and ABS Surfactant at 60oC for EOR Process

/in /by

Background: By 2021, global oil demand is expected to rise by 5.3 million barrels per day (bopd), while oil output is anticipated to decrease gradually. The fall in oil production was attributed to a decline in reservoir pressure and a depletion of oil reserves in the field. Surfactants are employed as a technique in Enhanced Oil Recovery (EOR) to enhance the extraction of oil.

Objective: This study investigates two different forms of surfactant solutions, specifically AOS (alpha olefin sulfonate) and ABS (alkyl benzene sulfonate). The two surfactants were evaluated at five distinct concentration levels, specifically 5%, 6%, and 7%. Both have a salinity level of 7,000 parts per million (ppm). AOS and ABS were selected as research materials because to their capacity to decrease interfacial tension.

Method: A phase behavior test was conducted to assess the durability of the foam throughout a 21-day measurement period at a temperature of 60°C. In addition, the research also seeks to ascertain the efficacy of oil recovery from the surfactant solution under investigation.

Results: This study is a controlled experiment conducted in a laboratory setting to examine the effects of AOS and ABS surfactants on sandstone rocks. The AOS and ABS surfactant solution was prepared by combining AOS powder and 70% ABS surfactant liquid with brine containing a salinity concentration of 7,000 ppm. The research procedure comprises multiple stages, such as density testing and phase behavior testing.

Conclusion: Based on this study, it may be inferred that concentrations beyond 5% did not yield middle-phase emulsions. Nevertheless, the oil recovery rate escalated to 68% as a result of the water flooding injection test and ongoing surfactant injection.

The Effect of Eco-Efficiency and Eco-Innovation Disclosure on Firm Value: Does Profitability Matter?

/in /by

This research aims to test whether profitability strengthens the influence of eco innovation and eco efficiency disclosures on the value of mining sector companies listed on the Indonesia Stock Exchange. Research data was obtained from annual reports and sustainability reports from the Indonesian Stock Exchange website and company websites. The sample used was 39 companies that met the criteria and were listed on the Indonesia Stock Exchange in 2018 – 2021. The sample data calculation technique used the cross sectional method via the eviews application. Hypothesis testing in this research uses multiple linear regression analysis methods. The results of this research show that eco innovation and eco efficiency have a positive effect on firm value, and profitability has an effect as a moderating predictor variable in the relationship between eco innovation and eco efficiency on firm value. This study differentiates samples based on more diverse dependent variables and involves moderating variables as amplifiers. Previous research did not use the two dependent variables, namely eco innovation and eco efficiency simultaneously so that the value of the company could not be determined as a whole whether the implementation of both had an effect on the value of the company. Then the researchers found that investors considered the application of eco innovation and eco efficiency to the value of mining sector companies.
