3. What is ISCWSA?
The “Industry Steering Committee on Wellbore Survey Accuracy”
aka SPE WPTS – Wellbore Positioning Technical Section
Our Primary aim* is:
Produce and maintain standards relating to wellbore survey accuracy
Raise awareness & understanding of wellbore survey accuracy
Set terminology and accuracy specification standards
Establish a standard framework for the modelling and validation of tool performance
*Blatantly plagiarized from the ISCWSA Mission

4. Who Can Join?
Anyone with an interest in wellbore positioning issues, technologies, data is welcome to attend ISCWSA meetings
and yes…
Reservoir Engineers
Geologists
Geodetic specialists
Geomagnetic specialists
Non-SPE members
Our members include :
Well Planners
Coordinators
Field Hands
Software Developers
Downhole Tool Manufacturers
Drilling Engineers
Technology Companies
People with General Interest in Survey Accuracy

5. Meetings General Meetings
Held twice a year – generally once in Europe and once in the US
Fall meeting has to be held in conjunction with SPE ATCE
Subcommittee Meetings
Held in advance of the General Meetings (generally the day(s) before)
Current subcommittees include:
Error Model Management
Collision Avoidance
Operator’s Wellbore Survey Group
Education
Survey QA/QC (revived)
Well Intercept (retired)
QA/QC (retired)
