Supporting information

Surveillance


  • Fibre optic monitoring utilising distributed acoustic and distributed temperature sensors provide valuable information on
    - production zones
    - cross flow
    - production and injection profiles
  • Permanent installation allows for dynamic flow conditions supporting effective decision making
  • A disposable, low cost fibre line well monitoring system has been successfully trialled onshore in the US and the UK. The system has been commercially deployed onshore United States and South America. It is currently involved in offshore trials for different operators in the UKCS

Data analytics


  • Apache UK utilises a reservoir simulator that takes full advantage of parallel and multi-core processing
  • The system can process large data volumes of varied at speed
    - seismic
    - rock properties
    - well history
  • Supports a range of simulations including compositional, thermal and black oil models
  • The system has since been deployed in another basin where Apache has interests
