Drilling Real-time Logging System is an application used to manage real-time logs collected while drilling in well-site. Real-time logs are data read from sensors of drilling equipments and manipulated by DAQ units. Related real-time data management are:

• Read data from WITSML-compliant service company or directly from Data Acquisition (DAQ) units of drilling equipments
• Store data to server
• Visualize and analyze data in real‐time and static/historical view using client application 
  Print data visualization or export to other formats

Wellsite Information Transfer Standard Markup Language (WITSML) 

• All  data  transfer  in  DREAL  system  use  WITSML standard to guarantee vendor/platform independence
• WITSML  is  a  standard  for  sending well  site  technical data  between  business  partners  (oil  companies, service  companies,  drilling  contractors,  application vendors and regulatory agencies)
• WITSML  is based on open  and well‐known  standards to ensure compatibility and platform independence:
  • eXtensible Markup Language (XML)
  • Web Services (SOAP, WSDL, XML, HTTP)

Sub Systems DREAL has three integrated sub systems:  DREAL has three integrated sub systems:

• WITSML Aggregator

  • Receive data (in WITS signal) from Data 
    Acquisition units, converts to WITSML, and send them to WITSML server

  • Support all records defined in WITS (25 records)

• WITSML Server
  • Stores real‐time data received from Aggregator to persistent storage (DBMS)
  • Serves real‐time data request from client(s)
• WITSML Client
  • Consumes real‐time data from WITSML server and visualizes real‐time data
• Key features:  
  •  Supports multi wells 
  •  Authentication: user – well mapping 
  •  Real‐time visualization: charts and numbers 
  •  Static visualization: specific date time 
  •  Templating: export/import visualization template 
  •  Print & export to other format
