Abstract: This paper does not deal with the development, challenges or any new findings related to carbon capture and storage technology (CCS) in the production of electricity by burning coal in thermal power plants, it aims to show how important this technology is and how much it promises the conditions for a fair and successful energy transition, especially for countries still rich in quality coal reserves, which include some of the countries of the Western Balkans. All the countries of the Western Balkans have entered the energy transition process, the level of transition is different. The rapid increase in capacity in the production of electricity from renewable sources also causes an accelerated abandonment of coal and a reduction in the production of electricity from its combustion. This again means even greater challenges in maintaining and balancing the electrical energy system, especially in conditions of high consumption or reduced production from renewable sources, putting energy system operators on additional challenges. In the last year, the region has already experienced one significant outage in the supply of electricity, the first time recorded, and more importantly, each of the listed countries had periods when they had a deficit of electricity. For example, Bosnia and Herzegovina was considered a significant exporter of electricity, but in January of this year, for the first time in its history, electricity production was lower than consumption. In order to overcome this, the countries of the Western Balkans, at least according to what we know today, are basing their energy transition on natural or liquefied gas, several projects are in the planning and implementation phase. The development and application of CCS in the production of electricity by burning coal significantly changes these plans and relations, especially since the use and introduction of this technology is necessary at some stage in gas burning as well. Simplified, why use imported gas instead of own coal resources during the energy transition, at least for the maintenance and ballasting of the electrical energy system. Of course, this does not mean giving up and stopping investment in the production of electricity from renewable sources, it should be continued wherever possible and justified, but the part necessary for balancing the system should be provided from one source that can be managed.

Abstract: Drill string plugging is a complex challenge in the oil and gas industry, often caused by a combination of factors related to fluid properties, wellbore conditions, and the nature of the formation. It can have severe consequences, including increased downtime, safety hazards, equipment damage, and higher operational costs. However, with proper planning, real-time monitoring, and effective fluid management strategies, the risks associated with drill string plugging can be mitigated, ensuring the smooth and efficient progression of drilling operations. The study however, explores the effectiveness of efficient drilling fluids properties optimization and management, together with real time monitoring of parameters, as a major means of providing solution to the challenge of drill string plugging during drilling operations. The study reveals that results from field experience, shows that adjusting drilling parameters, using LCMs, anti – sticking agents, monitoring performance and reacting promptly to signs of potential plugging, can help drillers to mitigate the risks of drill string plugging. Optimizing drilling fluid properties enables drillers to use the right fluid parameters for a specific region of the formation, while real time monitoring of parameters helps to ensure that the required fluid parameters are always met while drilling is in progress, especially in terms of solids control, rheological properties and mud weight. Real time monitoring of the formation properties is also useful in directing operators on the right fluid properties to use while drilling across formation of any specific property. This approach is rather a proactive/ preventive method, rather than a reactive method of solution to drill string plugging issues.
