SPWLA Local Chapter

On Tuesday April 18th, 2017 at Calgary, Alberta the Canadian Well Logging Society (CWLS) signed a local chapter agreement with Society of Petrophysicists and Well Log Analysts (SPWLA).

The CWLS would like to invite everyone who has been active in the past to renew their CWLS membership.

If you renew your membership soon it will convert to a SPWLA membership for the remainder of the year. By doing so you would have access to SPWLA resources and webinars.

We will also be inviting some distinguished speakers to present at luncheons later this year and into the future. Luncheon fees are much less for members.

Please consider renewing to gain access to a great technical resource and grow the CWLS membership back to past numbers.
