Oilfield Review Autumn 2011: 23, no. 3. Copyright © 2011 Schlumberger. ClearFRAC and HiWAY are marks of Schlumberger. In 1947, Stanolind Oil & Gas performed the first experimental hydraulic fracturing treatment in the Hugoton field in southwestern Kansas, USA. Since then, E&P companies have employed this reservoir stimulation technique extensively to enhance or prolong well productivity. Indeed...

Electrical Resistivity Imaging (ERI) has emerged as an important technique in geophysical surveys for gaining more information and locating hidden water. This method was used at Parit Raja, Johorto investigate the location of underground water storage. Two-dimensional (2D) geoelectrical imaging been this study. The three different locations study area to identify potential aquifer suitable bore...

Geophysical survey for groundwater was conducted in two newly built halls of residence (hostels) named Dangote and Shehu Idris at the second phase Ahmadu Bello University (ABU), Zaria Nigeria. The vertical electrical sounding (VES) technique resistivity method employed with Schlumberger array seven VES points distributed within hostels. Results showed that 4 to 6 geoelectric layers exist study ...

The results on the effectiveness of five 2D electrical resistivity tomography (ERT) survey profiles for Ag-Pb-Zn, fluorite, and barite exploration Mississippi Valley Type (MVT) magmatic deposits northeast Mexico, are presented. were made in areas with mining activities or mineralization outcrops. Schlumberger, dipole-dipole, Wenner array configurations used measurements. showed that electric ca...

Electrical Resistivity Imaging (ERI) and Vertical Sounding (VES) were deployed over the Uruagu landslide area. The main purpose of study was to characterize failure parameters in identify soil mechanisms. Ten profiles 2D ERI measuring 200 m each, thirty VES, with three VES along each profile, executed. Nine ten executed within site while one profile a residential street as control profile. Four...
