Dr. Cheng’s book, “Stress Corrosion Cracking of Pipelines”, has been published by John Wiley Publishing, U.S. It is the first book in this area in the world.

Dr. Cheng is coauthoring with Mr. Richard Norsworthy a new book “Pipeline Coatings”, which will be published by NACE International Publishing.

Research Profile

Dr. Cheng is an internationally recognized authority in oil/gas and pipeline corrosion research and integrity management. The overall goal of his research is to advance the mechanistic understanding of corrosion in oil/gas and pipeline systems, and to develop effective techniques for modeling, assessment, prevention and prediction of facility failure.

Dr. Cheng’s research has been driven by industry needs in four application areas: Downhole tubulars; Oil/gas gathering pipelines; Oil sands slurry pipelines; and Transmission pipelines.

His research interests include:

  • Corrosion in downhole environments: Modeling of tubular corrosion in SAGD/CO2 co-injection and production systems; Corrosion, microbiologically influenced corrosion (MIC) and fracture of coiled tubing; Modeling of corrosion of steel tubing in carbon storage.
  • Prediction of pipeline failure pressure by defect assessment: Analysis and assessment of ILI data and detected defects; Determination of failure pressure of pipelines containing defects; Modeling of stress concentration and local corrosion rate at defect under synergism of internal pressure, soil strain and stress concentration with consideration of steel grade and defect geometry; Modeling of defect growth for prediction of remaining service life of pipelines.
  • Coating failure mode and effect analysis: Shielding of cathodic protection (CP) by coating failures; Development of standard tst methods for nonshielding property of pipeline coatings with CP; Corrosion mechanism and kinetics in thin layer (tens of microns) of electrolyte under disbonded coating; Monitoring of coating disbondment by scanning Kelvin probe; Testing and modeling of permeability of multi-layered coatings to dissolved CO2, O2 and water.
  • AC corrosion of pipelines: Mechanism and threshold values of AC-induced pitting corrosion on pipelines; AC facilitated coating disbondment; Shift of CP potential under AC interference and modeified CP criteria for full protection of pipelins; Online monitoring and assessment technique for AC corrosion of pipelines.
  • Internal corrosion of pipelines: Pitting corrosion under deposit; MIC under petroleum sludge; Modeling of multi-phased lfuid flow and correlation of fluid mechanics with steel corrosion; CO2 corrosion fundamentals and parametric effects; Model for prediction of internal corrosion rate in CO2-containing environments; Multi-functional inhibitors for anticorrosion and anti-biodegradation.
  • Stress corrosion cracking of pipelines: Pitting corrosion and crack initiation on pipelines under CP; Coating failure and SCC initiation; Local activity of metallurgical features at micro- and nano-scales and its correlation with pitting corrosion; Welding metallurgy and its role in local preferential corrosion and crack initiation; Hydrogen permeatraion and trapping in high-strength pipeline steels,
  • Non-metallic pipe technology: Permeation of petroleum hydrocarbons into HDPE and th effect on chemical and mechanical stability of HDPE pipes/liners; Environmental stress cracking of HDPE pipe in ASP floods; Corrosion and fatigue of reinforcing steel cord in HDPE composite pipes.
  • Advanced coating technologies in oil/gas applications: Development of inhibitor-loaded smart coating technology; Super-oelophobic and hydrophobic nanocoatings for prevention of wax/paraffin deposit in tanks.

Initiatives ongoing

Dr. Cheng is leading the development of the Pan-Canadian Strategic Research Network on Oil/Gas Pipeline Corrosion and Its Management.

Dr. Cheng is working with the Schulich School Development to initiate an Industrial Research Chair (IRC) on Pipeline Corrosion Engineering.

Dr. Cheng is initiating an Industry Joint Project (JIP) on Microbiologically Influenced Corrosion of Coiled Tubing and Hydraulic Fracturing Facilities.

Dr. Cheng is serving as Treasurer of NACE Foundation of Canada.

Dr. Cheng is serving as the Guest Editor of the Special Issue on Pipeline Corrosion for the journal Corrosion Engineering, Science and Technology.

Dr. Cheng is chairing the NACE International Task Group (TG) 521 to develop a standard for testing of the compatibility of pipeline coatings with cathodic protection.
