Development of AO NPF GITAS with PAO GAZPROM
is designed to control technical condition of tubing, casing pipes and well strainer by a complex of methods including defectoscope and thickness measuring tool, highly sensitive thermometer, gamma-ray logging and pressure sensor.
In most drilling wells MID-K-GK is used to control:
- well construction having till 4 casings;
- compliance to casing interval project with different diameter and wall thickness;
- tail liner installation interval;
- casing integrity and rate of wear during tool operation.
In the running wells MID-K-GK allows to define:
- perforation intervals;
- cut through failure position;
- casing blowout in double casing string well program;
- factual installation intervals of sealing patch;
- factual installation depth of casing packer and etc.;
- well construction till 4 casings;
- corrosion intervals and casing rate of wear;
- casing failure intervals, requiring repair;
- first, second and third casing thickness.
