Abstract
A method may include determining a first particle size distribution for particulate additives in a first wellbore fluid circulated through a wellbore through an earthen formation, and determining a second particle size distribution for drilled cuttings resulting from drilling of the wellbore. The first and second particle size distributions may then be compared to determine a third particle size distribution for the combined particulate additives and the drilled cuttings. A lost circulation material having a fourth particle size distribution may then be selected based on the third particle size distribution and the selected lost circulation material may be pumped into the wellbore.
