Global warming has become a serious topic in the past few years, forcing the European Union to take immediate action to reach net-zero emissions by 2050. According to the US EPA 1: the warming effect was increased by 45% in the past two decades. As a matter of fact these new regulations will affect all major industries and their future objectives, especially the oil and gas industry. From a personal point of view, the oil market demand will start to decrease drastically, leaving the oil and gas companies in a position where they must rethink investing billions of dollars in meeting the required regulations and developing new oil fields. Wintershall Dea (WD), the leading European independent gas and oil company with more than 120 years of experience as an operator, is targeting to reduce scope 1 and scope 2 greenhouse gas emissions of its upstream activities (operated and non-operated at equity share basis) to net zero by 2030. Indeed, this is not an easy task; meeting the rising energy demand due to increased population and reducing emissions simultaneously can be quite challenging. However, in 2020 WD has set clear and measurable targets to drive the energy transition. Based on the research conducted by the WD last year, it was found that an essential part of the solution is in correctly measuring the problem. The correct quantification of the emission is an enabler to correctly plan for net zero. However, a bigger problem arises when the factors contributing to greenhouse gas emissions are being estimated, which leads to a lack of accurate emissions reporting. Utilizing measuring tools and sensors is one approach to reducing these uncertainties, but since the corporation does not control all of the equipment used in the field, installing new measurement devices is practically impossible. This master's thesis aims at developing a software tool that can document the associated uncertainty by gathering attributes to be associated with the input data from the primary contributors to greenhouse gas (GHG) emissions in well service activities. The software tool successfully incorporated the designed flowcharts from the previous year's project. New flowcharts were also added to some of the parameters. However, the software tool was only tested with fictitious data since real data collection was not possible due to time constraints.
