Technical challenges
Deepwater Services
In terms of deepwater wells, it can provide a wide range of cable, while drilling technology services.
Unconventional Resources
With the increasing number of unconventional reservoir logging, especially the high-end logging project (cross-dipole XDT, nuclear magnetic logging ERMT, imaging well logging ERMI) has been widely used in reservoir of tight sand gas, and 3D sound wave, far detection, pressure sampling and new technology has been applied wider and wider.
High Temperature, High Pressure
The high temperature logging system is a conventional logging surface system and downhole instrument with temperature resistance of 200℃ and pressure assistance of 140MPa, among which the surface system integrates the ESCOOL high-speed logging system, which is a fresh new logging software, and could realize the high-speed data transmission of upstream 1Mbps and downstream 500kbps on logging cable at 7,000m.
The same as the above.
The ERMI-HT is applicable to high-temperature water-based mud open hole well, and could convert the changes in rock resistivity near sidewall caused by the sidewall cracks, holes, bedding and others through array scanning imaging measurement into colored images, so as to display the stratigraphic characteristics of the sidewall intuitively and clearly. It could make fine evaluation on the siltstone formation, carbonate stratigraphy and carbonate formation through software processing.

The ERMI-SLIM is applicable to small-sized water-based mud open hole well, and could convert the changes in rock resistivity near sidewall caused by the sidewall cracks, holes, bedding and others through array scanning imaging measurement into colored images, so as to display the stratigraphic characteristics of the sidewall intuitively and clearly. It could make fine evaluation on the siltstone formation, carbonate stratigraphy and carbonate formation through software processing.
