SKL-76 hardware-software wireline complex for geophysical surveying of the production wells
The complex serves for geophysical surveying of the open boreholes of the vertical and directional wells of 120-245 mm diameter being drilled for oil and gas, both while tripping the complex in and while tripping it out. It is possible to work through the drilling tool with 90-110 mm inner diameter
estimation of relative dielectric permeability, which allows to separate oil-saturated reservoirs from the reservoirs flushed by fresh and mixed waters
reduction of downtime
geophysical surveying is performed during one trip
