Pipe Conveyed - Enhanced Side-Entry-Sub/SES

ENHANCED SIDE-ENTRY-SUB/SES 

 

The Enhanced SES System includes:

  • High-Strength High-Pressure Side-Entry-Sub (SES)
  • Cable Cutter Sub (CCS) attached to the bottom end of the SES
  • Flapper Valve (FV) mounted on top of the SES. 
     

The SES can be used without the CCS or the FV and yet it is the CCS/SES/FV combination that offers the performance and well control advantages listed.
This CCS/SES/FV system is compatible with 6-5/8”DP, 5-1/2”DP, 3-1/2” DP and 2-7/8” Tubing.

 

BENEFITS: 

  • The SES large flow-through hole allows high circulation rates of drilling fluid and running pipe-recovery or fishing tools at all times
  • The SES cable pack-off has been successfully tested at 9,000 psi
  • The SES Cable Cutter can be activated at any time by pulling a pre-defined high tension on the cable and it keeps the lower section of the cable attached to the SES after the cut is made
  • The SES Cable Cutter performance is independent of the cable strength and condition
  • The SES Flapper Valve provides an additional well control barrier while allowing pumping drilling mud or running tools through it
