Effect of Size and Concentration of a New Developed Natural, Biodegradable and Environmentally Friendly LCM on Fluid Losses Characteristics

Lost circulation refers to loss of part or whole drilling fluid into the formation while operataion. It wastes costly mud and time spent on rig operations. In this study, investigation a natural plant called, Prosopis Farcta (PF), has been done show its effectiveness as lost control material. A series experimental tests have conducted in order discover PF an LCM. Moreover, different particle sizes tested find out optimum size. Furthermore, variety concentrations investigate effect LCM percentage. And finally, for purpose comparison, similar precents most used conventional LCM, calcium carbonate well. The results that filtrate rate reference (without additives) was 32 milliliters 30 minutes. achieved reduction losses with addition CaCO3 about 47% by adding 20 ppb fine sized mud. Whereases, 76% obtained only 15 PF.
