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
-
-
