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 with peer reviewed technical papers on NMR technologies and applications and establishing a committee to organize 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. It is a great opportunity to learn and contribute to the advancement of NMR to formation evaluation as well as to network and work with the experts in this field.

The NMR SIG had a virtual board meeting on Oct. 9, 2020, and decided to make changes to the executive committee because some board members are no longer working in the petroleum exploration industry. The board has also agreed to hold an election for new executive members in the spring of 2021, and to hold a SIG conference in 2021. All SPWLA members are welcome to volunteers to serve the SIG board and to organize the SIG conference.
