Agenda

• Real-time data acquisition
• Data hub, real-time monitoring
• Project data store, visualization tools
• Drilling applications

3
IDEAL Data acquisition

• Front-end accept WITSML data objects
• Gather all wellsite data transmit WITSML data
  objects

4
InterACT Data hub

• Data aggregator / data store
• Gather data from multiple sources wells
• From the rig, surface sensors, gas, lithology,
  downhole tools, etc.
• Accept data in standard log files (DLIS, LAS,
  other ASCII formats), streaming WITS as well as
  streaming or static WITSML documents
• All data available on demand anytime
• File generation standard formats
• Streaming WITSML documents
• WITSML API Server

5
InterACT Data hub (2)

• Real-time monitoring

6
InterACT Data hub (3)

• WITSML API Server
• Well, Wellbore, Trajectory Log
• Objects grow in real-time as more data available
• Query any log curve over any index range
• Units conversion on request
• Data securely available
• Authentication with user name password
• Encryption with HTTPS (usually 128 bits)
• Users and access control rules administered
  within InterACT
