Published: February 2023

AbstractFoam flooding is a crucial enhanced oil recovery technique for profile control during the oil displacement process. The stability of the foam is the key factor for the success of foam flooding, but typical aqueous foams generally lose their stability in the presence of hydrocarbons because of their low oil tolerance. Non-aqueous foams possess outstanding stability in the presence of hydrocarbons as a result of their unique properties. However, few studies have been conducted on the stabilization mechanisms of non-aqueous foams in the presence of hydrocarbons. In this study, comparative experiments were performed to investigate differences in the stabilization mechanism between aqueous and non-aqueous foams. The results showed that a non-aqueous foam had excellent oil tolerance in a bulk foaming test. Then, the stabilization mechanisms of foams were investigated in terms of surface dilatational viscoelasticity and liquid film thinning. For a non-aqueous foam system, the maximum viscoelastic modulus of 55 mN/m occurred at a surfactant concentration of 5.0 wt%, which indicated that the foam was more stable. In a foam film thinning experiment, the thinning time of an aqueous foam system was shortened but the liquid film thickness was increased by crude oil, whereas crude oil increased the thinning time of a non-aqueous foam system but decreased its liquid film thickness. In a non-aqueous foam system, the film could remain stable for hours before rupturing, which indicated that its stability in the presence of an oil phase was excellent. These results are meaningful for the understanding of the stabilization mechanisms of oil-based foams and the employment of non-aqueous foams for enhanced oil recovery.
Carbon Storage Monitoring in Saline Aquifers Using CSEM Data
Authors: Amani Sajjad 
Published: February 2023

AbstractFinding economical non-seismic methods for safe and long-term underground Carbon storage monitoring is significant. Electromagnetic methods such as controlled source electromagnetic (CSEM) are among the top economical and powerful geophysical methods for this purpose to investigate more. However, the CSEM monitoring of Carbon storage can be affected by shallower conductive materials due to their strong electromagnetic wave attenuation. So, the processing of controlled source electromagnetic (CSEM) data is investigated for monitoring Carbon storage in marine saline aquifers. High attenuation of CSEM data in the high conductive media should be considered. For safe Carbon storage, the potential for leak detection is also checked here. The solution of Maxwell's equations in a goal-oriented adaptive finite element approach is used to decrease the computational cost. This modeling method is advantageous for nonlinear inversion because the parameters can be modified to reach a certain amount of accuracy. A Carbon storage reservoir in a saline aquifer modeled for testing the CSEM monitoring method. The results confirm the high potential of this method for demonstrating the areas of target Carbon storage, its leak, and its surrounding structures.

AbstractHigh Carbon dioxide (CO2) content presents a serious challenge in the development of Arthit Field. Accurate resource estimation, especially in the deep reservoir sections (Lower Miocene - Oligocene), depends on the accuracy of CO2 prediction. Formulated as a manual clustering approximation, conventional CO2 prediction requires intensive labor and fails to re-calibrate the model once the latest information is acquired. This paper introduces the application of machine learning concepts to the prediction of CO2. The proposed CO2 prediction methodology leverages machine learning techniques to enhance the understanding of a known field with existing CO2 concerns. Compared to the conventional manual clustering method, the machine learning model improves accuracy and reduces time and cost in the process of CO2 prediction and, in turn, resource estimation. Although our methodology is demonstrated specifically for CO2 in Arthit Field, it is equally applicable to other parameters and fields.
Carbon Nanotubes (CNTs) from Natural Gas: Challenges and Lesson Learnt

Published: February 2023

AbstractCarbon Nanotube (CNTs) is a carbon-based nanoparticle regarded as the "Futuristic Materials" for advanced applications. With the initiative to produce CNTs from natural gas included the potential to reduce greenhouse gas emission in "Company X" assets, the Fluidized Bed Chemical Vapor Deposition (FBCVD) and chemical leaching was selected for production technology. During project execution, challenges in scaling up processes and equipment from laboratory data were discussed as a lesson learned for new technology development.The CNT project began with laboratory experiments of the reaction between mimic natural gas and custom catalysts, followed by purification with acidic mixtures. Based on synthesis recipes, the prototype unit was designed and installed at the onshore plant to test with real gas under various operating conditions such as different gas ratio (HC/H2/N2), temperature etc. to verify production technique. The FBVCD reactor improves overall reactions in a short time while the new acid mixture shows high leaching efficiency, resulting in high CNTs yield and purity. With the promising results, the larger scale plant has been designed with a lean facility concept for brownfield modification.CNTs quality is varied with production recipes which 65% yield and 95% purity for Multi-Walled CNTs with a diameter of 50 nm, approximately can be achieved by prototype unit which it is comparable with commercial grade product. Consequently, this production technique has high potential for producing CNTs from natural gas. However, some engineering points must be considered when scaling units. Some issues which had a significant impact on the initial design were encountered when scaling-up the plant. In large scale fluidized bed reactors, fluidization parameters such as velocity, flow pattern are important for equipment design. Computational fluid dynamics (CFD) based on the actual flow test is needed because the scale factor based on laboratory and prototype tests has shown different results in larger vessels. Based on CNTs purification, chemical kinetics and chain reactions are mandatory for system design. Because their effects may be undetected on a small scale, but it may lead to completely change the design concept due to more bulky mixing effects. While the examples mentioned have made the system more complex, a larger footprint with a higher project cost, but can be resolved with different approaches.CNTs synthesis using natural gas oil&gas plants as carbon source was firstly initiated with promising results from actual field tests. This production technology is proven with higher product yield and purity compared with other conventional methods and larger scale plant is considered highly feasible. In technology development, the new things with less data are considered risky for investment, but it is a challenge that could open the new horizon for oil and gas development.

Abstract
Language has its influence in forming the individual and collective behaviours of communities in a society. The national language in Malaysia plays a vital role in the communication process between a community of Malays (who are the country's indigenous population), Chinese, and Indian (Tamil). The national language plays an important role in the national unity between the communities to achieve the slogan (One Malaysia), which was adopted by the Malaysian government in many aspects including the language. This Malay Language is used in official transactions in government institutions, local companies, the various ministries, and as a communication between multi-ethnic society of Malaysian. In light of this, the study will track the situation of Malay language before the British colonial rule and after the independence of Malaysia in 1957. It will search about the languages ​​spoken in Malaysian society, as Chinese, TTamil, and other languages such as Arabic which is taught through the (j-QAF) programme in government schools. The study will talk about the situation of the Malay language; the difficulties faced in using Malay as official language, and theIslamic dimensions and identity that it bears as well as the steps taken to improve the use of Malay language between Malaysian people to unite between them politically and socially in the community of multi-lingual such as Malaysia.
