Fundamentals of Horizontal Wellbore Cleanout delivers the latest methods regarding effective sand cleanout tools in horizontal wellbores. Providing the most relevant information, including sand bed formation, sand settling velocity, friction and hydraulics, this book covers the most effective tools and emerging technologies. Sections discuss the settling characteristics of sand and the effects of particle shape and size on drag coefficients, along with models for drag coefficients using experimental data. Numerical studies on sand transport efficiency as well as prediction models of sand concentration and an evaluation of friction between pipe and sand bed are also included. Illustrative case studies include cleanout with varying nozzle assemblies leading to optimum design on operation procedures, bottomhole assembly, and other lessons learned from known field experience. Rounding out with future research on cost-saving strategies including CO2 used as a washing fluid in water-sensitive formations, Fundamentals of Horizontal Wellbore Cleanout gives today’s petroleum and drilling engineers alternative methods to hole cleaning in today’s horizontal wells.
