Well logging suite

The equipment is intended for thermo hydrodynamic investigations in operating wells during field management. It works under the environment temperature of 0-120ºC and under the pressure of 60 MPa. The diameter of down hole device is 38mm. The equipment works as a part of computer-controlled well logging unit. It's furnished with single-conductor armored cable, personal computer and digital recording device. Two types of equipment are used for measuring – cable and self-contained devices. They can work in wells with corrosive and nonaggressive environment.
