Abstract There is no doubt about the presence of iron sand around west coast West Sumatra. Several studies have been carried out, but in Ulakan Tapakis area still under observation, and investigation its potential distribution. One methods that can provide models subsurface descriptions using goelectrical resistivity method. The geoelectrical application was used Wenner-Schlumberger array into ...

This research aims to identify landslide-prone zones using the geoelectric resistivity method in Pao Village, Tombolo District, Gowa Regency. The configuration used for data collection field is Wenner-Schlumberger four number of lines. result indicates that first line average founded each layer which suspected occur a soil and igneous rock form lava with 2.10 Ωm- 12.7 Ωm value. In second line, ...

The present paper consists in two parts, determined by the historical emerging production of Dipole Sonic Imager (DSI) measurements and results early 1990’s. DSI data were processed following methods simultaneously developed France USA Schlumberger . In first part dipole sonic S-wave velocity obtained late 1993 are confronted with other borehole scientific MM-1, entirely cored extensively logge...

In hydrocarbon reservoirs, the accuracy of saturation depends on precision water and resistivity (Sw Rw). A significant interpretation parameter is formation (interstitial or connate which is, uncontaminated by drilling mud that saturates porous rock) because it appropriate for calculations (water and/or hydrocarbon) from basic logs. The most reliable way to determine this value through determi...

We present improved combinatorial approximation algorithms for the uncapacitated facility location and k-median problems. Two central ideas in most of our results are cost scaling and greedy improvement. We present a simple greedy local search algorithm which achieves an approximation ratio of 2:414+ in ~ O(n= ) time. This also yields a bicriteria approximation tradeo of (1+ ; 1+ 2= ) for facil...

The conditions for the development of population growth and in area around City Bandar Lampung are very fast starting to get crowded, as happened District Natar South Lampung, especially Village Pemanggilan. This condition causes an increase need clean water resources line with groundwater exploitation. Therefore it is necessary map potential through aquifer mapping rock layers geoelectrical me...

In this study we estimated the aquifer hydraulic parameters of Damaturu, Yobe State, Nigeria, using electrical resistivity method. Schlumberger configuration was adopted for study. Five geologic layers, which are Topsoil, Clay, Sand, Sandy-clay, and Sand were delineated in area. The results measured revealed that values area ranged from 126 to 518 Ωm has an average 328 Ωm. thickness 39 71m with...

Abstract Efforts to reduce the clean water crisis do research in Karimunjawa. Research Karimunjawa at UTM coordinates 437524.656 m Easting and 9351066.022 Northing aim describe location groundwater, distribution of brackish freshwater conditions so that could make as a consideration making well drill or usual later crisis. uses geoelectric resistivity method Schlumberger configuration. configur...
