ABSRACT - [ Total Page(s): 1 ]Cuttings transportation during in non-vertical boreholes is necessary for oil and gas wells. Adequate cuttings removal from a well in drilling is critical for cost-effective drilling as high annular cuttings buildup often leads to high risk of stuck pipe, reduced rate of penetration and other impediments to standard drilling and completion procedures.This study investigates how rheological parameters influence the removal of cuttings in non-vertical boreholes. It contributes to work already done to ensure efficient hole cleaning process. In this study, the rheological parameters examined were

CHAPTER ONE - [ Total Page(s): 2 ]For turbulent flow in horizontal wells, the concept of using annular velocity (AV) as a measure of hole cleaning is insufficient. A more complete term called AVRD is introduced, which is the product of the AV and the square root of the hydraulic diameter. This term can be used to compare cuttings transport in turbulent flow in horizontal wells of different cross sectional areas. (Leising et al., 1998).Rheology which is the study of the flow and deformation of fluids is an important contributing factor to these problems. Rheology describes the relationships between shear rate an ... Continue Reading
