Maintaining the integrity of the drilling-fluid column is vital for safety and operational efficiency. Stable, controlled fluid density provides a primary pressure barrier during the drilling phase. Non-aqueous fluids (NAFs) provide huge benefits for

Uncertainties in the drilling process result in safety factors or safety margins sufficient to minimize risks in the drilling process. These safety margins represent inefficiencies in the system. This paper will discuss a method for reducing uncertai

Summary Lost circulation, a major complication of drilling operations, is commonly treated by adding materials of various types, shapes, and particle-size distributions to the drilling mud. Generally known as wellbore strengthening, this technique of

Summary Lost-circulation materials (LCMs) are often used to mitigate the loss of drilling fluids into subterranean formations. Well-known LCMs include ground marble, graphitic carbon, and cellulosic particulates. The carrier fluid’s ability to susp

Summary With increased drilling activity in deeper, harsher, and more-complex environments, controlling nonproductive time during drilling is critical to lowering the cost of well construction. Lost circulation (LC), one of the main contributors to n

Drilling operational parameters, such as pump rate, pipe tripping speed, and drilling fluid time-dependent rheological characteristics can impact wellbore pressure management and equivalent circulating density (ECD). It is important that ECD at any i

Weight material sag occurs during drilling operations when drilling fluids remain idle in the wellbore for time periods ranging from hours to several days at static or low-shear conditions. This paper presents a novel method of predicting real-time s

Summary Weighting-material sag is a reoccurring problem with many oil-based drilling fluids. Attempts to correlate sag tendencies to various rheological properties commonly used to benchmark drilling fluids have had limited success in prevention and

Curing lost circulation, one of the greatest contributors to drilling non-productive time (NPT), predominately has been addressed by applying particulate lost circulation materials (LCMs) into drilling fluids. Selection of LCM combinations has largel
