Eric Cayeux is a key member of the D-WIS team and his papers are stated as “must reading in the field” in the latest edition of JPT.

NORCE is working to enable interoperability between drilling systems, encompassing automation, monitoring or analysis systems. This will be achieved by developing semantical interoperability standards that allow the various components of drilling operations to exchange real-time data in a meaningful and unambiguous way.

D-WIS (Drilling and Wells Interoperability Standards) is an initiative for establishing recommended practices and standards that enable interoperability between all components, equipment and systems used in oil and gas well construction – regardless of the type or provider. The D-WIS initiative is now part of The Open Group OSDU Forum (, with the creation of "The OSDU D-WIS Program.

Levels of Interoperability:

1. Technical- drilling systems can exchange binary signals with each other’s but there are no requirements that the systems are capable to make sense of the binary data.

2. Syntactical- there is a protocol that allows to send/receive numerical values between drilling systems under access control.

3. Semantic- There is an agreement about the meaning of exchanged data between drilling systems.

4. Dynamic- New drilling data information can be added on the fly and drilling systems can interpret the meaning the data.

5. Organizational- Different disciplines can exchange drilling data regardless of their different domain perspectives.

Levels 1-4 are focus areas for D-WIS and the second phase of the Demo2000 project DDHub II (DSID), while number 5 is the focus area for DDHub+ in SFI DigiWells.

In December NORCE aims for a demonstration showing the progress for both D-WIS, DDHub II and DDHub+.
