Greetings from the SPE, Wellbore Positioning Technical Section, ISCWSAOur MISSION - "The primary aim of this group is to produce and maintain standards for the industry relating to wellbore survey accuracy. To set standards for terminology and accuracy specifications. Establish a standard framework for modelling and validation of tool performance. Raise awareness & understanding of wellbore survey accuracy issues across the industry."

We have comprehensive cross-industry, international representation with regular attendance from a wide variety of service companies, operators, and consultants, academia and software companies.The Industry Steering Committee on Wellbore Survey Accuracy was founded to dispel the confusion and secrecy commonly associated with wellbore surveying and to enable the industry to produce consistent, reliable estimates of survey-tool performance in today's wells. We achieve these goals through the production and maintenance of standards covering the construction and validation of tool error models.Work focused initially on Measurement While Drilling systems. They provide a large proportion of the total directional survey data world-wide and, because of their similarities between suppliers, are more amenable to specification standardization than other types of survey tool.There is no formal membership enrollment to join the ISCWSA and its meetings are open to all who wish to attend. The committee generally holds twice yearly meetings and has held 48 meetings internationally to date. The ISCWSA is also affiliated with the Society of Petroleum Engineers as the SPE Wellbore Positioning Technical Section, click here to join.Click this link for the Wellbore Positioning Technical Section Meeting MinutesClick here for Wellbore Positioning Technical Section Sub-Commitee information and documentsActive Sub-Committees : Collision Avoidance Sub-Committee Education Sub-Committee Error Model Sub-Committee Operator Wellbore Survey Group Sub-Committee Survey QA/QC Sub-Committee Well Intercept Sub-Committee - Released E-Book Elected ISCWSA WPTS Committee Members - Ross Lowdon, Schlumberger: Chair Adrian Ledroz, Gyrodata: Program Chair Ryan Kirby, SuperiorQC: Secretary Robert Wylie, xnDrilling: Treasurer Phil Harbidge, PathControl: Webmaster and QAQC Subcommittee Chair Mark Willerth, MagVar, H&P: Membership Chair Steve Sawaryn, Independent Consultant: Collision Avoidance Chair Andy McGregor, AJ Consulting Ltd: Error Model Chair Carol Mann, Dynamic Graphics Inc: Education Chair Heather Vannoy, EOG Resources: Director at large Adrian Ledroz, Gyrodata: Director at large AnaS Sikal, PathControl: Director at large Chad Hanak, SuperiorQC: Director at Large
