Why is WITSML important?
•
is the result of an industry collaboration to update the
widely used American Petroleum Institute WITS standard for moving
drilling data between rig and office based computer systems.
•
It provides data in a consistent XML format which is independent of
service company systems and geographic location.
•
It underpins the key objective to achieve leading edge productivity in
well delivery by providing enhanced real-time information sharing.
•
It facilitates standardisation in collaboration environments.
•
It provides a framework for smart tools deployment.

Reasons to Upgrade to v1.4.1
•
•
•
Simpler
– The WellLog and RealTime objects have been removed with the important parts of
their purpose being taken up by support in the Log object.
More efficient
– Compression. The WITSML standard supports HTTP and Gzip compression
resulting in less on-wire data for the same information.
– Query Optimizations. High frequency small row count data updates for Logs had
a high overhead of Log header to data block ratio in 1.3.1; This has been greatly
improved with support for headerless Log updates.
– Change Logs. The introduction of Change Logs enables clients to query servers
more efficiently.
Less ambiguous
– Improved documentation of the WITSML 1.4.1 API.
– WITSML Certification. Unlike WITSML 1.3.1 which had a weak and self-certified
approach, 1.4.1 servers can be tested against a published set of standard query
sequences on a defined set of data and the results compared against pre-defined
results enabling vendors to prove conformance to the WITSML 1.4.1 standard.
Cross-theme components
Foundation for all development
• Regulatory
• Security
• New data
• Certification
• Data quality/provenance/context
• Data management - life cycle data use
• Horizontal integration to data standards in drilling or
other domains
• Technology overlay - new API, binary API, etc.
