SCOPE OF APPLICATION
- Side-wall coring in oil and gas open holes
- Side-wall coring in cased holes
- Drilling perforation in cased wells with the large diameter of pipes
- Perforation channels of 35 mm in diameter in cased wells of large size
FEATURES AND ADVANTAGES
- Increase exploration efficiency by partially or fully replacing core sampling with side-wall coring
- Ensure accurate tie of samples to the geological section and oriented sampling of the interval of interest based on gamma-ray logging data.
- Provide casing and cement sampling when studying wellbore integrity of large diameter in long-term operation.
- Enable drilling perforation of cased wells of large diameter
- Ensure perforation channels of 35 mm in diameter in large-size pipes when performing workover of annular space cementing
