ISSUE OF DRILLING FLUID ABSORPTION IN THE ABSHERON FIELDS

Abstract

The hydrocarbon exploration industry faces a recurring and costly problem of drilling fluid absorption, particularly in difficult geological settings like Azerbaijan's Absheron fields. This diploma project explores the processes, factors, and mitigation measures related to high drilling fluid losses whilst building wells in different fields. The dissertation conducts geological analysis, field observations, laboratory trial investigations, and uses up-to-date technologies for an analysis of key absorption zones and for assessing the efficacy of existing fluid systems. Porous and fractured formations have identified as the primary factor causing unintentional absorption of fluid. This study assesses the practicality and effectiveness of innovative methods and incorporating new technologies, such as managed pressure drilling (MPD), loss circulation materials (LCM), polymermodulated fluid systems, nanomaterials, and real-time monitoring systems in the field of Absheron. In addition to providing comparisons of conventional and alternative methods, the study provides constructive advice on useful recommendations for reducing fluid loss and NPT, as well as improving well-bore stability. Ultimately, these outcomes are a step towards more secure operations in the difficult subsurface conditions of the region, improved drilling knowledge and performance as well as cost-reduction opportunities.
