This digital probe measures simultaneously 8, 16, 32 and 64 inch normal resistivity, single point resistance (SPR) and spontaneus potential(SP). Using one injection electrode and four sense electrodes users can log resistivity profiles with different depths of investigation and gain information about permeability, porosity, water quality and geological formation properties.

The QL40 ELOG is an in line sub. It can be combined with other logging tools of the QL (Quick Link) product line or operated as a standalone tool.

Application

• Bed boundary analysis
• Facies changes
• Quantitative geological formation properties
• Identification of hydrostratigraphic units
• Aquifer thickness
• Water quality
• Identification of hydrocarbon intervals
• Detection of ore body zones
