WITSML Project A New Information Transfer Standard
Project Goal • The “right time” seamless flow of well site data between operators and service companies to speed and enhance decision-making. Domain:Drilling, Completion, Well Services
Existing Standards • WITS • Designed, implemented, and established as an industry standard in the mid eighties • A binary file format for transferring wellsite drilling data • No standard programming interface • Limited data objects • It was great for it’s time, but times have changed.
Project Timing • Initiation of Project - Oct 2000 • Data Objects defined May 2001 • July 2001 – Working prototype • Wider industry roll-out at SPE Forum + Austin workshop 21/22nd Aug • Data standard design freeze 1st Oct • January 2002 – Commercial offering by the three major service companies and at least one small or midsize company
Software Design Decisions • Web Based & W3C Standards • Wide area networking • cross platform • XML data formats • Platform and language independent • SOAP for Programming Interface • Web server based • Platform and language independent • API Prototype in MS Visual BASIC
Open Sourced Deliverables • Definition of Data Objects & Catalogs • Example WITSML files • Validation tool for WITSML files • Example code to read and write simple WITSML data files • Documentation
Well Wellbore Rig Rig Equipment Pump Location Units Trajectory Target Bit Record Data Objects • Bottom Hole Assembly • Wellbore Geometry • Casing Scheme • Open Hole • Daily Operations • Fluids Report • Cement Job • Log • Real Time • Mud Logging
Future • Data standard owned by API & POSC • Still under discussion • Now has its own web presence • Steering Board will continue • Original companies plus others
Further Information • Web Site: www.witsml.org • Full details of object schemas • Documentation • Downloadable API components • WITSML Conference • Austin, TX, Aug 20/21 hosted by Schlumberger
