Erosion testing by DNV labs

Sand is an inevitable by-product during oil and gas production. Sand can have significant consequences for both the production and the assets. Key failure modes are related to sand particle erosion, sand accumulation, plugging or contamination by sand. 

The process laboratory at DNV headquarters at Høvik, just outside Oslo, has been in operation since 1995 and has been used extensively in experiments related to sand erosion, sand monitoring equipment and sand transport phenomena. Experience from experimental investigation and dedicated erosion testing form the basis of the recommended practice DNVGL-RP-0501 Managing sand production and erosion

The current test facility includes the following test rig set-ups:

  • Large scale high flow capacity erosion rig, capable of performing erosion testing in 5 – 10-inch set-ups with velocities up to 60 m/s
  • Sand blasting rig, capable of performing testing of candidate material samples to determine the erosion resistance as a function of particle impact characteristics according to ASTM G76-13. Impact velocities up to 150 m/s. 

DNV has previously performed erosion testing of the following components:

  • Rigid pipework
  • Unbonded flexible pipes (according to API RP 17B)
  • Sand monitoring equipment, including acoustic sand detectors and intrusive erosion probes
  • Down-hole sand screens
  • Single and multiphase flow meters
  • Erosion resistance testing of materials including steel grades, plastics, ceramics and erosion resistant surface coatings. 

Detailed erosion testing capabilities and testing range of each test rig set-up is specified in flyers below. 

Laboratory erosion testing is supported by advanced computer models such as Computational fluid dynamics (CFD) and multi-disciplinary advisory teams.
