Supporting information

Advances in flow assurance


  • Flow assurance is an ongoing challenges
  • Technology and mitigation processes are under development (e.g. chemical, ultrasonic disruption and localised heat treatment)
  • Using a LWIV, Shell cost effectively deployed ceramic sand screens in its Gannet field
  • These are been assessed by Shell for HPHT applications

EOR


  • There are EOR technologies that could deliver value for the UKCS
    - polymer
    - low salinity
    - miscible gas
  • BP’s low salinity Clair ridge development is expected to deliver an additional 35mm barrels of oil
  • Chevron plan to use polymer EOR for the Captain development with several new field developments being made polymer ready
  • Other EOR methods are demonstrating potential (e.g. microbial, steam, foam and CO2)
