| dc.description.abstract | The phenomenon of barite sag presents a significant hurdle in the drilling sector, posing a threat to operational efficiency, causing potential damage to machinery, and contributing to possible environmental hazards. This research comprehensively examines the role of polymer additives in Oil-Based Muds (OBMs) in lessening the effects of barite sag, while also exploring the corresponding economic considerations. Regular 80/20 OBM, in addition to OBMs combined with varying levels of polymer (0.25g to 0.75g), were scrutinized for key performance indicators such as flow point, yield, and strain flow.
Our study uncovers a strong relationship between the amount of polymer and the mitigation of barite sag. Importantly, the 80/20 OBM mixed with 0.625g of polymer yielded optimal results, achieving a delicate balance between a higher yield and a reduced strain flow, thus enhancing the mitigation of barite sag.
From an economic perspective, potential cost savings can be realized through enhanced drilling efficiency, minimized operational downtime, and improved wellbore stability. Our study further emphasizes the necessity of a thorough cost-benefit analysis when selecting the most economically viable strategies for differing drilling conditions and mud compositions.
In summary, this research offers critical insights to steer the drilling industry towards adopting more sustainable and cost-efficient methods, with significant implications for policy formation and industry standards. The results underline the importance of collaborative efforts among drilling firms, mud suppliers, and research entities in tackling the challenges posed by barite sag, and highlight promising avenues for future research. | |
