  4. The Wenner method is the most widely used method for measuring soil resistivity for electrical grounding (earthing) purposes. The Schlumberger method was developed to increase the voltage signal for the earlier, less sensitive instruments, by placing the potential probes closer to the current probes
  5. The conversion between values measured using the Schlumberger and Wenner methods is possible only in an approximate way. In any cases, for both Wenner and Schlumberger methods the electrode spacing between the currents probe corresponds to the depth of soil investigation and the measured apparent soil resistivity is referred to a soil volume as in the figure

In this study, we apply a two-dimensional joint and separate inversion of data with dipole-dipole, Schlumberger, and Wenner configurations on real and synthetic data. We show that joint inversion is better than using separate inversions because the joint inversion uses a higher density of data and different current distribution in the subsoil.

Wenner-Schlumberger Untuk Penampang Horizontal dan Pendugaan Vertikal (Karanth, K.R., 1987). Metode geolistrik lebih efektif jika digunakan untuk eksplorasi yang sifatnya dangkal, jarang memberikan informasi lapisan di kedalaman lebih dari 1000 atau 1500 kaki. Oleh karena itu metode ini jarang digunakan untuk eksplorasi minyak tetapi lebih banyak digunakan dalam bidang geologi teknik seperti. Adapun pengukuran tahanan jenis di lapangan menggunakan konfigurasi Wenner-Schlumberger karena memiliki resolusi vertikal dan horizontal yang baik dengan 7 lintasan maksimal berbentang 112 m. Total luas lahan yang diteliti adalah 2 Ha atau sekitar 32% dari luas gunung Lumpur Sedati.

The DSI dipole shear sonic imager combines monopole and dipole sonic acquisition capabilities for the reliable acoustic measurement of compressional, shear, and Stoneley slownesses. The transmitter section contains a piezoelectric monopole transmitter and two electrodynamic dipole transmitters perpendicular to each other The Wenner-Schlumberger and Dipole-dipole method can detect differentiation of limestone types and also the exposed underground river successfully. However, compared to Wenner-Schlumberger array, Dipole-dipole array reveals less vertical accuration.. Therefore, on this research, the best method to detect water saturated zone or gourndwater in the karst system is the Wenner-Schlumberger method. This software is designed for Schlumberger, Wenner and pole-pole spreads. The possibility of displaying several surveys simultaneously facilitates the comparison between close surveys. The displayed curves, as well as the electric model of the active survey, with altitudes of the grounds and its raw data, are printed on any printer supported by Windows® and can also be transferred as.

Baris 5 : Jenis lokasi-x untuk titik-titik data. Masukan angka 0 jika lokasi elektroda. pertama dalam konfigurasi digunakan untuk mengukur titik data Schlumberger yöntemi de Wenner yöntemi ile aynı prensipte çalışır ancak tek farkları, Wenner'de 4 elektrotun yer değişimi gerekirken, Schlumberger yönteminde ortadaki iki gerilim elektrotu sabit iken dış kısımdaki akım elektrotları yer değiştirir. Bu ise büyük saha ölçümlerinde kolaylık sağlamaktadır Konfigurasi Wenner-Schlumberger adalah konfigurasi dengan sistem aturan spasi yang konstan dengan catatan faktor n untuk konfigurasi ini adalah perbandingan jarak antara elektroda C1-P1 (atau C2-P2) dengan spasi antara P1-P2 seperti pada Gambar 3. Jika jarak antar elektroda potensial (P1 dan P2) adalah a maka jarak antar elektroda arus (C1 dan C2) adalah 2na + a. Proses penentuan.

Beberapa jenis konfigurasi yang biasa digunakan untuk pengukuran geolistrik adalah, konfigurasi Schlumberger, konfigurasi Wenner, konfigurasi Dipole-dipole dan variasinya. Konfigurasi Wenner. Pengukuran jasa survey geolistrik ini dilakukan dengan cara meletakkan titik titik elektroda dengan beda jarak satu sama lain yang sama. Elektroda yang bersebelahan akan berjarak sama (AM = MN = NB = a. Konfigurasi elektroda ada enam jenis yaitu: konfigurasi elektroda Pole-Pole, Pole-Dipole, Dipole-Dipole, Wenner dan Schlumberger serta Wenner-Schlumberger. 2.2. Teknik pengukuran geolistrik. Teknik pengukuran geolistrik ada tiga macam yaitu mapping, sounding dan imaging. Masing-masing teknik pengukuran geolistrik dapat dilakukan untuk tujuan yang berbeda. Untuk tujuan penentuan airtanah.
