DEEP-HOLE SEISMOMETER (VARIABLE-RELUCTANCE TYPE)

Abstract

A variable-reluctance seismometer suitable for long-term operation in a deep well was designed, constructed, and laboratory-tested. The seismo meter was operated in a deep well near Grapevine, Texas, and in a deep well near Hobart, Oklahoma. The field operations showed that the seismometer meets the design objectives and is satisfactory for use in more extensive field programs.
