“…The ability of a geological formation to take CO 2 injection fluids can be characterised as injectivity (Md Yusof et al 2021). As mentioned before, the non-condensable impurities have the ability to decrease stream density, this will in turn cause mass flux to drop over the same pressure drop (Yusof et al 2022). However, as viscosity decrease, it will increase the mass flux which eventually effecting injectivity (Wang 2015).…”

“…As part of the efforts to limit global warming, various CO 2 reduction schemes and technologies have been proposed by multiple international organization and government which is initiated by the United Nations (Mohd Pangi and Md Yusof 2022). One of the recent initiatives was the Paris Climate Accords where the main objective revolves around limiting the release of GHG into the atmosphere and control the temperature rise by 1.5 to 2 °C each year (United Nations 2016).…”

Deployment of carbon capture, utilisation, and storage (CCUS) technologies to mitigate climate change and overturn CO2 emissions growth would require transformational changes comprehensively. The primary focus of this manuscript is on the impurities standards and limitation that can ensure project feasibility in the long run. There is a need in the industry for guidance on purity analysis prior to capture, shipment, and storage of carbon dioxide. This is because the cost to capture and separate the stream is proving to be very costly that can make the project to be unfeasible to operate. Following this further, this manuscript discusses the previous research and best practices that establish standards for acceptable impurities that might present in the stream and its effects towards the CCUS system. Consequently, this manuscript also provides better understanding on the impurities effects towards CCUS technology system in general. Understanding these limitations, may provide cost effective solution for CCUS problems that revolves around the impurities in CO2 stream. Impurities can affect some components of the carbon capture and storage process. It is clear that even a little number of impurities can cause the carbon dioxide stream properties to change. There are two primary factors discussed in this manuscript that affect how a CCUS system responds to a CO2 stream that contains impurities: a physical and chemical effects.

Growing energy demand heightened by climate change challenges has seen the oil and gas industry tightly embrace smarter and more sustainable technologies. The motivation is to quickly grasp net-zero targets, while safely optimising oil-gas production. By its nature, the industry has the ingenuity to eliminate unnecessary carbon emissions. However, traditional development plans relied on the use of wells with minimal or no emphasis on the well completion in terms of optimum deliverability. This would produce a mixture of oil and excessive unwanted fluids such as water and/or gas which requires costly energy-intensive processes. Although the process has been optimized to some extent and often re-injects these unwanted fluids back to the reservoir, there has been not enough attention to the environmental impacts as these repetitive treatment processes of the fluids results in discharging excessive and unnecessary Greenhouse Gas (GHG) into the atmosphere. The issue is now widely recognized to be one of the industry challenges in its drive toward net-zero energy delivery. A case study of a heavy crude oil field with a strong water drive, located in a natural reserve in the Marañon basin of the Peruvian Amazon is presented. Here, the implementation of autonomous inflow control devices (AICDs) technology, through a knowledge management process, has made it possible to significantly reduce the volumes of water produced, which are reinjected again, thus generating significant savings in fluid lifting, treatment and energy consumption associated with the operations in this field. The study introduces a workflow that uses a publicly available GHG footprint estimator to evaluate the carbon intensity of different oil and gas field development plans. The estimator predicts the amount of GHG emitted from any individual operation, process and treatment involved in a field development from exploration to delivery at the gate of a refinery. Having this calculation enables the operators to recognize the major GHG emitter operations and optimise the process toward net zero using new technologies, methods and/or workflows. The workflow has then been applied to the field located in the Peruvian Amazon to illustrate the significant impact of flow control technologies on the reduction of GHG emissions and achieving net-zero targets. For example, the amounts of carbon intensity, GHG emission and energy consumption from the field have been estimated to been reduced by up to 56%, 64% and 78% respectively with AICD completions compared to a case of non-AICD completion such as stand-alone screen (SAS) was installed in the wells instead. This study provides the engineers with a workflow to quantify the impacts of the use of new technologies especially flow control devices. It also illustrates the significant role of flow control technologies in achieving net-zero production.

Reduction of carbon emissions has become a global objective driving both government and private sectors to develop and mature technologies that fit this purpose. This paper will evaluate how deploying Autonomous Inflow Control Devices (AICDs) in a field, with hundreds of wells completed with AICD completion, reduced carbon emissions during prolonged periods of production. The study introduces a workflow that uses a publicly available Greenhouse Gas (GHG) estimator for different field development plans. The production data of 28 wells from a reservoir in the Sultanate of Oman were analyzed. The AICD were self-regulated based on the properties of the fluid passing through, which optimizes oil production while reducing the production of unwanted fluids. To ensure an accurate comparison, the data underwent extensive pre-processing, and some modelling was conducted. The collected data, including fluid properties, formation characteristics, and operational processes were all used to feed the estimator, which then run for various scenarios with and without AICD cases to predict the energy consumption and greenhouse gas emissions associated with each operation and treatment involved in the field development. By calculating these emissions, operators can identify the major sources of emissions and energy consumption and optimize their processes to reach net-zero. The results show that the use of rate-controlled production (RCP) AICDs completion in the wells has resulted in reduced capex and opex including drilling a reduced number of wells (both producers and injectors), less requirement of energy extensive production, surface processes and re-injection of unwanted fluids to achieve the target production rate for the field. The study's findings revealed that AICDs have significant effects on improving oil production up to 35% while reducing water production by 50%, as well as on the environment. For instance, the use of AICD completions in the field was estimated to reduce carbon intensity, greenhouse gas emissions, and energy consumption by up to 51%, 47%, and 110%, respectively; compared to non-AICD completions, such as when a stand-alone screen (SAS) is installed in the wells. Also, the finding shows that oil production was a major contributor to GHG emission and energy consumption for non AICD completion scenarios compared to any other operation or process involved in oil production. This study provides, for the first time, a workflow to quantify the impacts of the use of new technologies especially flow control devices on the reduction of carbon emissions. It also illustrates the significant role of flow control technologies in achieving carbon net-zero production.
