Using Real-Time Downhole Monitoring to Overcome Deferred or Lost Production
May 13, 2020 No Comments
Downhole monitoring in SRP/PCP/ESP installations to help take pre-emptive measures to reduce downtime. The Issue
4mm Quadline
With all the benefits of our innovative 4mm design, this multi-conductor TEC provides the highest performance and reliability available on the market.
4mm Quadline – Downhole Instrumentation Cable
The GEO PSI 4mm quadline downhole instrumentation cable is designed to provide maximum strength and reliability, in an easy to handle form factor. This cold formed, tungsten-inert-gas welded cable meets UL2225 standards, and far exceeds the performance of outdated 1/4″ cable that is commonly found on the market.

Specifications
Metal Jacket:
Material
Stainless Steel 316L or Incoloy 825
Most of the cables we ship are made of high quality Stainless Steel 316L. This material provides both great strength, and corrosion resistance. If however your particular well has an exceptionally hostile downhole environment, you may want to consider Incoloy 825. This metal jacket material provides extra protection against sulfuric and phosphoric acids, oxidizing acids, putting, stress corrosion cracking, inter-angular corrosion, and damage caused by high concentrations of downhole CO2.Â
Outside Diameter (1)
4mm / 0.160″
Wall Thickness
0.76mm / 0.030″
Seam
Gas Tungsten Arc Weld
Common in the aerospace industry, this method of welding reduces porosity and offers superior strength. While more difficult and time consuming, gas tungsten arc welding ensures the reliability needed to survive the most hostile downhole environments.
Weld Quality (2)
Eddy Inspection
This is a method of inspection in which electromagnetic fields are utilized to check the quality of the weld. By monitoring the resulting electrical conductivity and magnetic permeability of the cable, faults that would otherwise be invisible to the naked eye can be detected.
Insulation:
Material
PFA
Perfluoroalkoxy insulation provides exceptional performance at high-temperatures, and great mechanical strength which allows it to perform reliably in hostile downhole environments.
