Acid-Soluble Lost Circulation Material for Use in Large, Naturally Fractured Formations and Reservoirs

Abstract

Abstract Lost circulation is an extremely difficult challenge to overcome in areas with large natural fractures. Few lost circulation materials (LCMs) are capableoftreatingsuch zones where severe to total losses occur, particularlyin the reservoir sections. Particulate-based LCMs are commonly used to help mitigate losses but mightnot contain the proper particle size distribution (PSD) or acid-solubility characteristicsfor useful application in production zones.
