The macro processes of the oil industry and their influence on the energy transition

Introduction

Currently, the oil industry is at an inflection point. The macro processes that make it up, from extraction to marketing, are being re-examined under the lens of sustainability and energy efficiency. This industry, traditionally linked to the development of the global economy, must adapt to a world increasingly oriented towards reducing environmental impact, optimizing its efficiency to contribute to the transition towards cleaner energy sources.

The macro processes of the oil industry and its influence on the transformation of the energy sector towards a more sustainable future are very relevant in the formation of a more responsible energy panorama. This transformation, gradual and meticulously planned, must be guided by the emergence of new technologies, innovation, and digitalization, among others. These elements are fundamental to aligning the oil industry with global sustainability goals, while ensuring its importance in the global economy.

Macro processes of the oil industry

The oil & gas industry is a significant component of the global economy, encompassing a series of interconnected processes known as macro processes. These are divided into three main stages: Upstream, midstream, and downstream. Each one is described below:

• Upstream: It is the phase that includes the exploration, drilling and extraction processes. It is related to the search for oil fields or natural gas reserves, the drilling of exploratory wells, and the operation of wells that recover and bring crude oil or natural gas to the surface. It is the beginning of the value chain, where natural resources are identified and extracted.
• Midstream: This phase involves the transportation, storage and initial processing of crude oil and natural gas. This stage acts as a bridge between the upstream and the downstream. It is responsible for ensuring that extracted resources are transported safely and efficiently to refineries or processing plants.
• Downstream: It is the final phase, where the extracted hydrocarbons are transformed into finished products and then distributed to consumers. This stage connects directly with customers and end markets, being the decisive stage in determining the availability and price of energy products.

Each of these macro processes is important for the operational efficiency and profitability of this industrial sector, being intrinsically interconnected in terms of product flow and coordination of operations.

Environmental consequences of the oil industry

The oil & gas industry has multiple environmental consequences, being a great source of pollution and ecological degradation. Extraction activities have a direct effect on water and soil pollution. The use of large volumes of water in processes such as hydraulic fracturing ( fracking ) is consistent with the generation of toxic waste. These wastes, along with hydrocarbon leaks, manage to infiltrate nearby water bodies and soils. In addition, erosion and land degradation increase the risk of contamination of groundwater.

Likewise, it is one of the largest contributors to greenhouse gas emissions. The burning of fossil fuels releases large amounts of carbon dioxide, methane, and other gases, accelerating global warming and climate change. Another impact is deforestation, caused by the construction of infrastructure for the extraction and transportation of oil and gas; These deforestations result in the loss of biodiversity and the degradation of natural habitats, altering ecosystems.

Finally, exploration and production processes generate a variety of solid and hazardous waste, which can contaminate soils and waters, affecting both terrestrial and aquatic biota. On the other hand, the noise pollution derived from these activities has adverse impacts on fauna.

Spills and leaks during the extraction, transportation, storage or refining of hydrocarbons cause irreparable damage to ecosystems and affect socioeconomic activities.

Macro processes in oil & gas: Promoting the energy transition

An overview is presented focused on how each stage and its processes are influenced by the transition towards cleaner and more sustainable energy sources.

Upstream: Innovations for sustainable exploration and extraction

• Exploration: Integrating advanced technologies, such as advanced seismography and advanced geospatial analysis, this phase can align with energy transition goals. These techniques allow for more precise exploration, reducing the need for extensive drilling and decreasing dependence on fossil fuels.

• Drilling: The use of advanced techniques such as directional drilling and extended well technology minimizes the environmental footprint and maximizes extraction efficiency. These methods allow access to more complex reserves with less impact, favoring a balance between current production and sustainable development.

• Extraction: Implementation of low-impact fracking and optimized management of water resources used in extraction, along with monitoring well integrity, make oil and gas extraction more sustainable and respectful of ecosystems.

Midstream: Improving efficiency and reducing environmental footprint

• Processing: The adoption of carbon capture and storage (CCS) technologies and more advanced gas treatment processes, such as pressure swing adsorption, contribute to emissions reductions and align this process with global sustainability goals.

• Storage: Innovations in oil storage, such as the use of underground caverns for natural gas storage and large-scale energy storage solutions, help balance energy supply and demand, facilitating a smooth transition to alternative energy.

• Transportation: The design and use of smart oil and gas pipelines, as well as low-carbon shipping and more emissions-efficient transportation vehicles, reinforce sustainability throughout the transportation chain.

Downstream: Promoting cleaner fuels and sustainable distribution networks

• Refining: Advances such as the integration of hydrotreating and fluid catalytic cracking processes improve energy efficiency and reduce emissions from oil refining processes. The inclusion of biofuels and the optimization of existing refining technologies are essential for the production of cleaner fuels.

• Distribution: Efficient distribution and marketing networks for petroleum products, which integrate both fossil fuels and renewable energies, become essential for a balance between current energy needs and the transition towards a more sustainable future. The implementation of smart logistics systems and the adoption of higher standards in energy efficiency significantly improve sustainability in the distribution phase.

The integration of advanced technologies and the adoption of cleaner and more efficient practices at each stage of the macro processes of the oil industry are crucial for an effective energy transition. These advances not only mitigate environmental impacts, but also ensure the industry’s relevance in a changing and sustainability-oriented energy future.

Conclusions

The macro processes of the oil & gas industry have decisive effects on the transition towards a more sustainable energy future. The industry is adapting through technological innovations and cleaner practices in all its phases: from exploration and extraction to refining and distribution. These changes are aimed not only at improving efficiency and reducing environmental impact, but also at aligning the industry with growing demands for global sustainability.

The implementation of advanced technologies and sustainable practices in each stage of the macro processes highlights the commitment to reducing the environmental footprint and promoting cleaner energies. This highlights that this industrial sector continues to be relevant and competitive in an energy context that is constantly evolving and increasingly inclined towards sustainable and renewable options.
