GNPOC/Scale/Surface CPRS
Location: GNPOC NE-03 & NEE03
Trial Period: May 20th to August 20th , 2014
CPRS Units: two sets of  6”x 8” surface units,  one for each
Report Date: September 3rd 2014
 
Before the Installation of CPRS units
  • NE-3 & NEE-3 flow lines frequently chocked due to scale deposition
  • Scale inhibitor injected by 20 L/D for each
  • Even with scale inhibitor injection scale continued deposition
  • Flow line acid cleaning carried out frequently

After the installation of CPRS units
  • NE-3& NEE-3 ENMAX CPRS installed on 20/05/14
  • Chemical injection stopped after ENMAX installed as requested by vendor
  • NE-3 &NEE-3 Parameters after ENMAX installed steady

  • NE-3 tripped on 8/8/14 
  • NE-3 flow line inspected by remove NRV near well head and NRV at OGM-5 found clear no scale
  • NE-3 test line and production line, which was not treated by CPRS, was almost totally blocked
  • NE-3 blocked test line and production line cut and fabricated another one
  • NE-3 started back on 18/8/14 and well parameters steady THP 240 and FLP 220 psi
  • From NE-3 flow line inspection confirmed OGM-5 production and test header blockage 90%
  • Due to blockage of OGM-5 NEE-3 parameters high
