is designed to determine bed dip angles and dip direction, rock stratification and fracturing in oil and gas, core-parameter and engineering-geological wells including inclined horizontal wells.
The dipmeter is used with logging stations of any type which are equipped with any three-core armored cable.
Features and advantages
• increased radial investigation depth of near-wellbore focused circular scanning;
• high accuracy of bedding elements, fractures, other anisotropic rock planes measurement in vertical and directional wells;
• identification of near-vertical and vertical fractures including the fractures which do not cross the borehole; their space orientation coordinates within the near-borehole space of up to 1 m in diameter.
