¨ Controls seepage loss in weighted systems
SX-PlusTM
A solid solution for fluid loss
at high temperatures
Sx-Plus™ provides a thermally stable fluid loss additive for high 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. Sx-Plus™ carbonaceous 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.
Sx-Plus™ has a very high melting point unlike resins or gilsonite based products. This carbon-based material has been treated at temperatures over 600°F (315°C) providing excellent thermal stability downhole.
