The oil and gas industry is involved with severe corrosive/sour environmental conditions due to H2S, CO2, moisture content. National Association of Corrosion Engineers (NACE) has developed standards enable users select suitable materials for given sour which utilize laboratory testing. A failed piping sample (API-5L-X65) was removed from a pipeline after 15 years service. Optical microscopy use...

An experiment featuring waterhammer in viscoelastic pipes is presented in which the effects of pipe-wall viscoelasticity on waterhammer pressures are investigated. A large-scale pipeline apparatus made of polyvinyl chloride (PVC) at Deltares, Delft, The Netherlands, has been used to carry out waterhammer experiments. Tests have been conducted in a reservoir-pipeline-valve system consisting of a...

Slippery Liquid Infused Porous Surfaces (SLIPS) are a relatively new and promising development in the surface engineering world. Bio-inspired with superior omniphobicity robustness, SLIPS have enjoyed success several scientific applications, spanning multiple industries from marine environment to medical field. Inorganic fouling is one such challenge managed overcome by disrupting both depositi...

Microbially influenced corrosion (MIC) in oil field pipeline systems can be attributed to many different types of hydrogenotrophic microorganisms including sulfate reducers, methanogens and acetogens. Samples from a low temperature oil reservoir in Nigeria were analyzed using DNA pyrotag sequencing. The microbial community compositions of these samples revealed an abundance of anaerobic methano...
