JDX-3Dr Well Gamma Logging Equipment Geophysical Sp Equipment
Description
The JDX-3Dr probe is a multi-functional logging instrument that captures natural gamma emissions and electrical resistivity readings at two distinct depths (16 inches and 64 inches). Additionally, it records spontaneous potential, single-point resistance, and temperature. By generating resistivity profiles across various depths, this tool provides critical information about the formation's permeability, porosity, water quality, and other geological attributes. It operates effectively in uncased boreholes filled with either water or mud, making it an indispensable tool for detailed subsurface analysis.
Description
Core Features & Benefits
1.
Precise Digital Transmission: The probe converts the collected geological data into digital signals and transmits them to the surface, thereby preventing any cable-related disturbances that could compromise data accuracy.
2.
Automatic Measurement: Equipped with a stable power source and adaptive measurement systems, the probe functions automatically, eliminating the need for manual operations.
Application Areas
•
Lithofacies Study: Examining changes in lithofacies patterns.
•
Formation Property Quantification: Offering detailed assessments of geological formation properties.
•
Hydrostratigraphic Unit Identification: Recognizing and characterizing hydrostratigraphic units.
