Wellsite Information Transfer Standard Markup Language

“The ‘right-time’ seamless flow of well-site data between operators and service companies to speed and enhance decision-making”An Open Information Transfer Standard for the Oilfield

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.

WITSML Roadmap Planning

2011 Release – 1.4.1

• June 30 – Candidate Release for public review• September 23 – 1.4.1 Published• Marketing name = WITSML 2• Product launch

– IADC Annual Conference March 2012 (San Diego, CA, US)– Intelligent Energy – March 2012 (Utrecht, The Netherlands)

• 1.4.1 Product Certification– More robust testing– Testing application to automate– Publically available test data– Commercial terms (particularly for non-members to be defined)

• Bug fixes to be issued as necessary• New object process to continue development as industry

requirements are identified and defined beyond 1.4.1

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.
