Temperature Logging
Wireline or Coiled Tubing Deployment — Slim 34 mm (1-3/8") or 43 mm (1-11/16") tools conveyed via electric line, slickline or coil tubing (E-coil or memory).
GR & CCL — Ensures accurate depth correlation and lithology/zonal identification.
Advanced Processing & Interpretation — Full datasets are compiled and analyzed post-job using our analysis software, delivering detailed visualizations, correlations, and actionable insights.
Tool Specifications
Applications, Detection, and Interpretation
Cooling anomalies — May indicate fluid influx, injection storage, or gas expansion (Joule-Thomson cooling).
Heating anomalies — May reflect production, injection storage, fluid flow, or exothermic reactions.
Sharp changes — May point to leaks, channels, micro-annuli, fluid communication or other types of cross-flow.
Key uses and detections include:
Fluid entry/exit points, behind-casing flow, or leaks.
Cement placement, tops, and plug integrity.
Gas/liquid movement related to SCVF/GM.
Zonal isolation (Hydraulic Isolation), barrier effectiveness, and post-intervention confirmation.
Thermal monitoring during circulation, injection, production, or interventions.
Injection profiles (warmback or coolback transient analysis for waterflood, steam, or EOR distribution).
Fracture evaluation (cooling effects for stimulation effectiveness).
Reservoir surveillance (water breakthrough, horizontal flow characterization, conformance optimization).
SAGD monitoring (steam chamber growth and efficiency).
Low-flow qualitative detection where other tools lack sensitivity.
Enhanced Capabilities & Advantages
Combined with Production Logging Tools (PLT) — Delivers single and multiphase flow profiles: fluid identification, flow rates correlated to thermal anomalies, diagnostics for crossflow/channeling, and abandonment flow confirmation.
Proven in Low-Flow Wells — Captures subtle events; integrates with acoustic data.
Through-Tubing Efficiency — Slim design reduces downtime, costs, emissions.
Regulatory Compliance — AER Directive 020 (Well Abandonment), Directive 51 (Injection and Disposal Wells), Directive 080 (Well Logging), Saskatchewan PNG015, and BC guidelines; boosts LMR/LLR profiles.
Complements Tools — Pairs with CVT, Noise Logging, CHAT, Flow Meter and Cement Bond Logs for hybrid diagnostics.
Versatile Deployment — Supports E-Coil/memory on coiled tubing for challenging environments.
Simple & Reliable — Sensitive, works in open/cased hole, minimal complexity, useful across well life.
Typical Output & Visualization
Data appears as a continuous curve (temperature vs. depth), overlaid with other logs. Real-time plotting aids field decisions: logging analysis software provides advanced post-processing and interpretation.
