Selective water shutoff treatment

MOC-One is a hydrocarbon based Micro-Matrix cement slurry for selective water shutoff. MOC-One slurry remains inactive when contacting an oil- or gas-producing zone but reacts when contacted by water. 

Ideal for near-wellbore applications in naturally fractured reservoirs

 Such as:

  • Sealing water-bearing formations with natural fractures
  • Stopping unwanted water production coming from channels and micro-channels behind the casing
  • Sealing leaks or pinhole leaks in the casing
