The paper presents as one of the recent "Schlumberger" developments
in the well logging instrumental field a new tool: the formation microscanner
(FMS). The whole of the equipment to be lowered into the bore hole is represented
in fig. 1 together with the configuration of one of the measuring pads, two
of which are mounted in the present form of the instrument but more are being
envisaged for subsequent developments.
The multiple applications of the new technique of interest both for the petroleum
the mining industries – and not only for geologists but also for petrophysicists
as well as for production and reservoir engineers – are mentioned and
corresponding examples are presented. The technical interest of the FMS procedure
is made conspicuous by the information it provides as an additional image of
the geologic formation characteristics presenting a simple handling and interpretation
as well as an easy transmission in the case of the petroleum exploration. It
is paralleled by an obvious economic interest, the new instrument allowing
to reduce and complete the conventional well-coring programmes.
Key words: Sabba Stefanescu, Schlumberger, electrical well logging, formation
microscanner.
