Overview
The Cased-Hole Logging is the measurement and acquisition of various downhole parameters using different downhole tool combinations from WellRay, which can help customers grasp the subsurface reservoir dynamics in real time, accurately monitor fluid distribution and wellbore health, quickly locate problem layers, optimize production plans, and reduce costs. At the same time, it can ensure wellbore safety, extend the life of the oil well, improve the recovery rate, and meet the environmental requirements, and is the “intelligent eye” for the efficient development of oil and gas fields.
Key Objectives
- Assess well integrity: Check cement bond quality, casing corrosion, or leaks.
- Monitor reservoir performance: Track fluid saturation, pressure, and flow profiles.
- Evaluate completion efficiency: Verify perforation effectiveness or sand control.
- Detect undesirable fluid movement (e.g., water/gas breakthrough).
- Measure remaining hydrocarbon reserves (time-lapse logging).
Applications Scenarios
- Well Integrity Checks: Diagnose cement failures or casing leaks.
- Production Optimization: Identify zones contributing to water/gas production.
- Reservoir Surveillance: Monitor saturation changes (e.g., depletion, water encroachment).
- Workover Planning: Guide decisions on remedial cementing, perforation, or plugging.
- Abandonment Verification: Confirm zonal isolation before well closure.
Modern Innovations
- Fiber-Optic Sensors: Distributed Temperature Sensing (DTS) and Acoustic Sensing (DAS) for real-time monitoring.
- Advanced PNL Tools: Multi-detector systems for precise saturation analysis.
- Slimhole Tools: Compact designs for through-tubing logging in complex completions.
- Digital Integration: AI-driven interpretation software for faster diagnostics.
