SPWLA France Chapter

Français : 

SPWLA France, section locale française de la Society of Petrophysicists and Well Log Analysts (SPWLA *), est une association à but non lucratif, sur participation individuelle, dont l’objet est de faire partager les connaissances, le savoir faire et l’expérience de terrain des scientifiques, ingénieurs, managers et étudiants sur les techniques d’évaluation des formations géologiques. Cela couvre les mesures de surface, subsurface et laboratoire, incluant tous les types de données obtenues au cours des opérations de forage et de logging.

De 1966, année de sa création, à  2018, l’association a porté le nom de  ” S.A.I.D.” , Société pour l’Avancement de l’Interprétation des Diagraphies. Le site web la-said.org a été fermé en 2020 et remplacé par spwla-france.fr.

English : 

The SPWLA France Chapter (formerly SAID), French Chapter of the Society of Petrophysicists and Well Log Analysts (SPWLA)*, is a non-profit making professional organization aiming at sharing knowledge, know-how and fieldwork experiences among scientists, engineers, managers and students about geological formation evaluation techniques covering surface, subsurface and laboratory measurements.  It embraces all data acquisition types performed while drilling, logging or with the mean of surface surveys.

From 1966 to  2018, the chapter name was : ” S.A.I.D.” , Société pour l’Avancement de l’Interprétation des Diagraphies. The website la-said.org has been closed in 2020 and replaced by spwla-france.fr

*The Society of Petrophysicists and Well Log Analysts (SPWLA) is a nonprofit corporation dedicated to the advancement of the science of petrophysics and formation evaluation, through well logging and other formation evaluation techniques.

Main goals

The association will propose initiatives, coordinate them and implement the necessary means to the realization of activities for the promotion of the science of the formation evaluation :


    • Diffusion of information to any interested person
    • Communication and illustration of good practices applied to oil & gas, mining and energy industries
    • Preservation and diffusion to professionals of working , technical, scientific and ethical standards
    • Setting, maintenance and promotion of the science of formation evaluation. To do so, the association organizes workshops, conferences, demonstrations, communication and training campaigns and participates to the professional networks in the field of petrophysics
