Plugging efficiency of flaky and fibrous lost circulation materials in different carrier fluid systems

Lost circulation is one of the most significant contributors to wellbore instability and causes an increase in drilling operation costs. It also a major contributor nonproductive time must be minimized for improved economic operational performance. The objective this research provide tools information about specific loss management techniques that drillers can use minimize lost circulation. This study involves comprehensive approaches test plugging efficiency three different materials (LCMs) from two groups (flaky fibrous). highlights carrier fluids (drilling fluids) determination optimum fluid properties. Different fracture sizes effect various LCM are analyzed. impact LCM’s shape, size, physical chemical properties along with discussed. Examining particle size distribution before after mixing shows capability while maintaining minimum porosity permeability plug. helps strengthen gradient formation by knowing actual sizes. primary work precisely analyze these factors on LCMs investigate their potentially resolve or severity problem.
