Lost Circulation

G-PLUS R

PRODUCT DESCRIPTION

G-PLUS R provides a thermally stable fluid-loss additive for high or low temperature wells. Based on extensive lab tests and field applications, it is known that a specific particle size will seal the face of porous sands and other formations helping reduce the differential pressure transfer. G-PLUS R graphitic particles with a PSD ranging from 40 mesh to > 200 mesh (425 to > 75 microns) are classified in that specific size range to effectively reduce fluid loss. G-PLUS R has a very high melting point, unlike resins or gilsonite-based products. This carbon-based material has treated temperatures over 600°F (315°C), providing excellent thermal stability downhole.
