At LBBC Baskerville, our vision is to provide products that will help to enhance corrosion control, prediction and management in order to improve on the safe and efficient recovery of hydrocarbons. With the ultimate goal of playing a role in preventing catastrophic corrosion related failures across the industry.

Working in partnership with the University of Leeds, specifically a team of corrosion experts lead by Professor Anne Neville; LBBC Baskerville are continuously developing new products that can help replicate field conditions realistically with the aim of improving corrosion testing, repeatability and industry standards.

Future applications and products will include:

  • Severe service HPHT chemically inert autoclave with electrochemistry
  • HPHT autoclave with electrochemistry in dynamic conditions in the presence of H2S
  • Fully automated system with in-line inhibitor injection, brine sampling and the ability to monitor the brine chemistry for the duration of the test (O2 monitoring, pH monitoring, Fe2+ concentration monitoring)
  • Coupon/electrode retractable system to remove/insert coupons periodically to eliminate pre/post-test corrosion and to analyse corrosion mechanisms over time without performing multiple tests
  • Constant chemistry autoclave system featuring all of above

Advanced autoclave systems to incorporate:

  • Dynamic loading machine (stress corrosion cracking)
  • In-situ tribometer (tribo-corrosion)
  • In-situ jet impingement (Erosion-corrosion)
  • Flow loop (Flow-induced corrosion)
  • XRD/Raman Flow cells (In-situ corrosion product formation)
