Cased holes technical condition control

According to "The technical rules of downhole logging and wireline works in oil and gas wells" a complex of general studies of cased holes technical condition includes: gamma-ray logging (GR) to assure tying of the obtained data to the section, casing collar locator (CCL), acoustic cement bond logging (ACBL), gamma-gamma cement bond logging (CBL) or gamma-gamma inspection and thickness measuring (GGDTM), thermal log (TL). The following set of downhole tools allows to accomplish this complex of general studies by only one round-trip operation.
The set consists of:
  technological tool (TM);
 tying tool (ALM, GK, TD);
  compensated acoustic logging tool (4AK);
 sectioned acoustic cement bond log sonde tool (AKTsS);
 acoustic thickness gage - profiler (on the reflected waves) (ATP);
  caliper-profiler (4SKP);
  downhole gamma-densitometer-thickness gage, high-temperature high-pressure (SGDT-6TB);
  acoustic imager (scanner) (AST).
