Resistivity SIG SPRING 2018 Meeting: CALLING FOR TOPICS & PAPERS! 

SPWLA is a nonprofit corporation dedicated to advancing the science of petrophysics and formation evaluation through well logging and other techniques applicable to exploitation of gas, oil and other minerals. Founded in 1959, the organization serves as a voice of shared interests for scientists in the petroleum and mineral industries, strengthens petrophysical education and increases awareness of roles petrophysics play in the oil and gas industry as well as the scientific community.

Nested under SPWLA and based in Houston, Resistivity Special Interest Group (Rt-SIG) is an active group of resistivity specialists, and for people generally interested in resistivity-related formation evaluation. Rt-SIG organizes meetings twice a year (Spring & Fall), featuring technical presentations and discussions on a variety of resistivity formation evaluation topics.

The Rt-SIG 2018 Spring Meeting is tentatively scheduled for Wednesday 14 March 2018 at Rice University, Houston. We are now calling for special topics, abstracts and presentations.

The registration fee will be $10 for students, $20 for SPWLA members and $30 for non-members.

Resistivity Special Interest Group

The Resistivity Modeling Special Interest Group(Rt-SIG) is dedicated to the modeling, characterization, and application of resistivity logging for petrophysical evaluation.Founded in November 1995, the Rt-SIG is an independent, member-run, not-for-profit organization. It provides an open discussion platform to petrophysicists, scientists, log analysts, individual consultants, people from academia and etc to share (and explain) “strange” resistivity log responses and conduct high level technical discussions to acquisition, interpretation, and integration of resistivity wellbore data.

There are two meetings every year; one is in Spring and the other is in Fall.Announcements are sent out two months prior to each meeting to all of the members. Please feel free to pass on meeting information to those who may not be on our email distribution list. If you are interested in attending, but are not currently on the distribution list, please contact one of the Officers:
