    Effendhy, H. Junaidi, R. Abbas and B. Z. Malik

    Encountering partial or complete lost circulation is not an uncommon occurrence in Caltex Pacific Indonesia’s (CPI) Duri field in the Central Sumatra basin of Indonesia. Lost-circulation rates can range from one barrel per hour to total losses.
