Drilling fluids are essential for safe and efficient oil and gas well construction, performing critical functions such as cuttings transport, pressure control, borehole stabilization, and bit lubrication. Traditional manual testing according to API standards provides only intermittent data, often leading to delayed responses and increased risks of kicks, lost circulation, stuck pipe, or formation damage – especially in complex unconventional, deepwater, and high-pressure/high-temperature wells. This paper propos...

Drilling fluid properties – density and rheology (plastic viscosity, yield point, gel strength) – are essential for wellbore stability, pressure control, hole cleaning, and minimizing non-productive time (NPT) in oil and gas drilling. Traditional manual methods (pressurized mud balance, Fann 35 viscometer) are periodic, labor-intensive, and delay corrections, increasing risks of kicks, lost circulation, and instability. This study proposes an intelligent automated system for real-time monitoring and control us...

Accurate, real-time characterization of drilling fluid rheological properties, such as plastic viscosity, yield stress, and gel strength, is vital for optimizing oil and gas drilling operations and advancing sustainable exploration. This study assesses advanced sensor technologies - ultrasonic sensors, inline viscometers, optical flow analyzers, and microfluidic sensors-for automated, real-time measurement of these properties in water-based, oil-based, and synthetic-based muds. Experiments utilized a closed-loop f...

The monitoring of open-pit slope stability is critical for safety, economic, and environmental reasons. The comprehensive approach to monitoring has been analyzed, addressing safety, economic, technological, ecological, legislative, and social responsibility aspects, ultimately contributing to sustainable mining practices. Various methods and technologies for monitoring slope stability have been determined as essential. Visual inspections are useful, but they depend on the qualifications of the observer and may ov...

Drilling fluid viscosity is a critical parameter influencing the efficiency and safety of drilling operations, yet real-time monitoring under dynamic conditions remains challenging due to varying temperature, pressure, and flow rates. This study develops algorithms for continuous, automated viscosity monitoring of drilling fluids to optimize drilling processes. The primary objective is to design robust algorithms capable of accurate viscosity predictions in real-time, addressing limitations of traditional manual m...
