Hydraulic fracturing, a widely adopted stimulation technique in the oil and gas industry, significantly contributes to CO2 emissions. This paper aims to identify the sources of emissions, explore options and methods for reducing the CO2 footprint, and enhance safety measures for personnel involved in hydraulic fracturing operations.

The study examines various factors that collectively contribute to minimizing the environmental impact of hydraulic fracturing. It discusses techniques implemented in Petroleum Development Oman (PDO), as well as other available and potential approaches for reducing CO2 emissions, including customized equipment selection accompanied by emission calculations, spill and pollution prevention measures, adoption of electric fracturing fleets and solar energy, utilization of four-phase separators to eliminate post-fracturing flaring and hydrocarbon waste, among others.

The paper highlights green initiatives already implemented in PDO and quantifies their positive outcomes. Furthermore, it outlines a roadmap for future improvements in the short and long term, assesses the economic and reputational impact resulting from the implementation of such initiatives, and addresses associated requirements and challenges.

The paper presents a diagram evaluating the level of positive economic, environmental, and reputational impacts relative to the costs and efforts involved. Detailed guidelines are provided to assist well engineers in selecting appropriate solutions for different geographical and geological conditions in various fields. By discussing global trends towards environmentally friendly practices in the oil and gas industry and drawing on PDO's experience, this paper unveils strategies for tailoring available solutions to specific conditions and circumstances.
