Induction resistivity logging of boreholes
WebSedangkan induction log mengukur konduktivitas formasi yang merupakan kebalikan dari resistivitas. Induction log bekerja dengan baik pada sumur yang mengandung fluida non-konduktif pada lubang bor seperti oil-based mud, atau fresh water mud. Contoh log yang termasuk dalam induction log adalah induction deep log (ILD), induction medium log … WebIt is the only resistivity tool that will work in non-conductive borehole fluid and in non-metallic casing (no resistivity tool works in steel casing). A Dual Induction Log (DIL) consists of a deep-reading induction device, and is …
