Resistivity SIG 2021 FALL Meeting -Open registration

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.

We are excited to let you know that the Resistivity Special Interest Group (Rt-SIG) 2021 Fall Meeting will be held virtually on Tuesday, October 26th, 2021. Please refer to the attachment for the detailed agenda. The meeting will start at 8:00 AM (US Central Time) and end by 12:30 PM. The registration is open now. You are welcome to register at our Eventbrite registration page . The registration fee will be $10 for students, $20 for SPWLA members and $30 for non-members. Once registered, you will receive a confirmation email with instructions on how to join the online meeting. Feel free to contact us at [email protected] if you have any questions.

Looking forward to seeing you at our SIG meeting.

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.

SDAR Workgroup

Initiated by Rt SIG and several EM experts in the Oil & Gas industry, Standardization of LWD Deep Azimuthal Resistivity Services (SDAR) workgroup is formed in June 2016. It is an industrial advisory committee, which is composed of technical experts and representatives from oil companies, oilfield service companies, and universities. The sole purpose of SDAR workgroup is to promote deep azimuthal resistivity LWD services within the industry and provide recommendations on standardization of these services from the technical perspective. For any further information, please contact Rt SIG committee. The workgroup have organized several meetings and its progress has been shared regularly at Rt SIG biannual meetings. Previous updates and meeting notes are archived in the following files.
In April 2018, the workgroup decided to prepare a comprehensive document with a consistent outline to describe current deep resistivity tools and its related service from four major service companies: Schlumberger, Halliburton, Baker Hughes GE, and Weatherford. The outline of the documents covers all aspects of deep azimuthal resistivity LWD services, including tool physics and configuration, key parameter definitions, major applications, real-time workflow, pre-drill studies, post-drill studies, and reference. The documents are also archived in the following files. It is highly advisable to always contact service companies for any further information and explanation.
