Application of Gas Ratio Analysis in Reservoir Evaluation.docx

One of the oldest techniques used in drilling, and one that is usually carried out by mud logging contractors, is the analysis of gas from the drilling formation. This procedure is particularly important for the production team during exploratory drilling operations and is critical for wellsite geologists as it supports formation appraisal. The technique of Gas Ratio Analysis, which is used to identify fluid types and identify which layers contain hydrocarbons, is the main topic of this study. This is accomplished by using straightforward ratios of light gases that are measured by a gas chromatograph inside the mud logging machine. This allows for real-time computations and depth data to be plotted alongside mud logs. Three wells in the Burhan land field were chosen for this study's application of gas ratio analysis, which helps to show how hydrocarbons are distributed within the formation and helping to identify optimal locations for perforation and production.
