Upcoming Event: SPWLA 2026 NMR SIG Conference
📍 Location: Celle, Germany (Hosted by Baker Hughes)
📅 Dates: 10–11 September 2026
The SPWLA 2026 NMR SIG Conference is an in-person technical meeting bringing together NMR experts in petrophysics, logging, core analysis, data processing and correction, and NMR sensor technology applied to subsurface characterization.
The conference is designed as an off-the-record technical forum, with no publication and no recording (pictures or videos) of the material presented, ensuring an open and candid environment for technical exchange, discussion, and collaboration.
Registration & Attendance
The SPWLA 2026 NMR SIG Conference is an in‑person event with limited capacity due to venue access, safety, and logistics constraints.
Registration will close on August 21.
Registration Fee Structure:
- SPWLA members: 200 USD
- Students: 100 USD
- Standard registration: 250 USD
The registration fee covers full access to the technical program, coffee breaks, and lunch on both conference days.
Participation will be managed on a first‑come basis once registration opens. Early registration is strongly recommended. Due to site access and safety requirements, late registrations may not be possible.

About the NMR SIG
NMR SIG was established in September 2016, as one of the outcomes of the 2016 SPWLA Spring Topical Conference on NMR, to provide a focal organization designed to bring the NMR community of experts and practitioners together to educate each other as well as the broader community on the proven concepts and applications of NMR.
The SIG will also serve as a venue to discuss new ideas for technology and applications to enhance understanding of the formations and the fluids contained in them. The SIG’s initial goals include establishing industry standards for NMR measurements, publishing a special volume in Petrophysics, and organizing future SIG conferences and workshops.
Membership in the NMR SIG is open to all current members in good standing of the SPWLA at no additional fee.
To join the NMR SIG, you need to login to your SPWLA account and modify your profile to indicate that you would like to become a member. You can communicate with the Executive Committee of the NMR SIG by emailing [email protected].
