XRT™ Ceramax™ E Proppants


XRT Ceramax E Product Photo

XRT™ Ceramax™ E proppants are a cost effective solution available in a 20/40 mesh size for use in a broad range of field applications. Use of the eXtreme Resin Technology (XRT) system to encase an economy ceramic has yielded a proppant with high fracture flow capacity and resistance to cyclic stress.

Typical Applications

Fracture treatments:

  • At closure stress up to 12,000 psi [83 MPa]
  • At bottom-hole static temperatures from 175 - 450°F [79 - 232°C]
  • That require proppant flowback prevention, especially under sever stress cycling
  • When wellbore clean-out is a concern

Technical Advantages and Benefits

  • Higher conductivity than uncoated ceramics
  • Proppant flowback control even under extreme conditions utilizing Stress Bond™ technology
  • Superior cyclic stress resistance
  • Temperature stability for both extended pumping and storage times
  • Increases near wellbore conductivity over uncoated ceramics
