Summary The increasing complexity of drilling operations requires reliable tools to optimize well design and drilling fluid performance. In this paper, we present the hydraulics and drilling simulation (HDS) software, an advanced engineering platform developed to enhance drilling fluid management and operational efficiency. The framework integrates predictive and advanced algorithms for key parameters, including cuttings transport, hole cleaning efficiency, equivalent mud weight, equivalent circulating density (ECD), rheological behavior, dynamic temperature profiles, surface pressure standpipe pressure (SPP), and gel strength. By coupling these capabilities, HDS helps engineer the well design and supports on-site decision-making to reduce risks, improve wellbore stability, and minimize nonproductive time. A comparative study with other engineering tools available in the market is illustrated, providing insight into the added value of the software. Furthermore, a case study is included to demonstrate its practical implementation and performance in realistic drilling conditions. We detail the technical architecture and key functionalities of HDS, highlighting improvements in hydraulic accuracy and operational planning compared with conventional approaches and underscoring its role as a practical tool for modern drilling challenges.
