ECE® version 5.4 is released!

New or significantly revised features in version 5.4 include:

  • Erosion tool: a new calculation tool for estimating particle erosion damage, together with corrosion, is provided in the downhole tubing module. This is based on industry standard calculation methods

  • Data table output: raw data from the corrosion calculation can be exported as an Excel table showing the corrosion rates as a function of distance or depth, in addition to the existing graphical and tabular report formats. This applies to both flowline and tubing modules

  • Bulk calculation: the spreadsheet style input function introduced in ECE 5.3 has been extended to allow inputs of API gravity, acetic acid content and chemical inhibition information for the flowline module

  • Corrosion resistant alloy (CRA) selection: the CRA selection tools now allow input of organic acid content for calculation of the pH used in the selection rules

  • Licence Implementation has been improved. Reactivation of the ECE Licence is required to use ECE 5.4


Wood Group Intetech’s ECE® program is a tool for the quantitative estimation of corrosion rates and the selection of materials for oil and gas production systems and processing facilities. At the heart of ECE-5 is a new and improved model for corrosion analysis and material selection, firmly based on laboratory data, and field calibration studies both with pipeline and with downhole tubing.

The software is available as a stand-alone PC version for single users or a server-based system for multiple users.


ECE® 5 is fully supported. Licensees receive regular updates, including further functionality improvements and new materials data, and have the benefit of expert technical support.

Invaluable tools

  • Corrosion rate predictor for carbon steel in sweet and sour conditions that considers different options for corrosion control
  • Risk prediction tools that evaluate the risk of carbon steel failure
  • Corrosion-resistant alloy evaluators that select the most suitable alloys for the specified environmental conditions and automatically take into account the risks of corrosion, pitting and stress-corrosion cracking
  • Life cycle cost calculators that evaluate the economics of carbon steel and corrosion-resistant-alloys option based on net present value, so that material cost comparisons can be made
  • An alloy-tubing and pipe manufacturer database

Key features

  • Corrosion-rate prediction for sweet and sour service conditions based on the fundamental chemistry of the solubility of the corrosion products
  • Corrosion evaluation incorporates critical factors such as oil API gravity, water cut, flow rates and angle of flow
  • Calculated outputs for multiple positions along a flowline or up a tubing string
  • Instant output updates, for example, corrosion-rate profiles, with changes in input parameters
  • Carbon steel failure risk evaluation considering both generalised and pitting corrosion risks
  • Quantitative evaluation of corrosion-resistant-alloy suitability for a matrix of conditions that covers temperature, partial pressure of carbon dioxide and hydrogen sulphide, chloride content and pH
  • Life cycle cost analysis that takes into account fabrication speed, pipe-laying method and means of corrosion control
  • Help files with technical background and references
