WGSB-3.5 MONOCONDUCTOR ( 1/8" ) AWG 24 Wireline Logging Cable

1. Normal-Temperature Conventional Production Wells (Open Hole/Cased Hole)

Applicability: Vertical/directional wells (build rate ≤30°) with continuous downhole temperature ≤150°C and well depth ≤4000m.

Operations: Routine open-hole logging, cased-hole production logging, standard perforating, conventional coring.

2. Onshore Shallow/Medium-Deep Oil & Gas Wells

Applicability: Shallow wells (≤2000m) and medium-deep wells (2000-4000m) with normal formation temperature (≤150°C).

Operations: Shallow reservoir evaluation, basic formation parameter testing, daily production dynamic monitoring.

3. Low-Risk Old Well Recommissioning/Simple Workover Wells

Applicability: Mature wells with only minor scaling and slight hole restriction, free of corrosion and with downhole temperature ≤150°C.

Operations: Simple workover logging, basic casing inspection (CCL), auxiliary scraper operations in shallow wells.

4. Onshore Conventional Exploration/Development Wells

Applicability: Onshore shallow exploration wells with stable formation temperature and pressure and no corrosive gas/fluid, as well as shallow to medium-depth production wells for low-yield and conventional development; regular wellbore trajectory without high-curvature sections.

Operations: Initial formation evaluation, basic parameter acquisition logging after drilling and completion; meets the requirements of low-cost logging construction for batch conventional exploration wells in oilfields.

1. High-temperature wells (continuous downhole temperature ＞150°C) and deep/ultra-deep wells (well depth ＞4000m).

2. Sour service wells (containing H₂S/CO₂) and corrosive fluid environments.

3. High-curvature horizontal wells (curvature radius ＜300m) and wellbores with severe friction/scaling.

4. Geothermal well operations, high-pressure well testing, and heavy oil well operations.

5. Offshore oil & gas well operations.
