With the development of different segments within the drilling technology in the last three
decades, well drilling has become possible in harsh downhole conditions. The vertical well …

Inadequate hole cleaning often leads to challenges in drilling and well completion
operations such as low rates of penetration, pipe sticking, losing tools, difficulties in …

The increasing necessity of challenging wellbore structures and drilling optimization for
improved hole cuttings cleaning has been growing along time. As a result, operator …

Increasing cuttings bed height is a serious concern during extended-reach well drilling. In
order to predict and prevent cuttings bed height increase, it is essential to study how the …

Hole cleaning during directional well drilling is a major concern in the oil patch and must be
monitored and properly controlled during the entire drilling operation. Inadequate drilled …

Field experience has shown that the inefficient transport of small cuttings is a main factor
contributing to excessive drag and torque during the drilling of a deviated hole; however …

Effective removal of small, sand-sized solids is critical for successful drilling and completion
operations in sand reservoirs. Recent experience in extended-reach drilling also indicates …

One of the major concerns during drilling horizontal and directional wells is proper hole
cleaning. If there exists a stationary bed, generally, an increase in the fluid velocity will erode …

In oil and gas exploration and development, drilling a hole is one of the first and most
expensive operations. The continuous demand from industry to reduce costs and …

Poor cuttings transport in deviated wells limit drill rate, induce excessive torque and drag, or
in severe cases result in a stuck pipe. This paper presents a generalized data-driven model …
