Modernizing WITSML Data Exchange: Bridging SOAP and ETP Protocols for Migration Automation

With the energy sector’s shift toward digital oilfield operations, the ability to efficiently migrate and utilize wellsite drilling data is critical. WITSML, the Wellsite Information Transfer Standard Markup Language, is a cornerstone standard for well data exchange but is often hampered in legacy environments by the use of the SOAP (Simple Object Access Protocol). ETP (Energistics Transfer Protocol) now serves as the modern, high-performance backbone for WITSML v2.0+. This paper details both the motivation and technical architecture for a SOAP to ETP conversion utility, comprehensively analyzes the protocol differences impacting performance, bandwidth, latency, and data integrity, and offers a practical approach to seamless WITSML data migration
