Expert In-House Log Analysis That Turns Raw Wireline Data Into Clear, Actionable Insights
At Reliance OFS Canada, our dedicated 24/7 in-house log analysis team provides fast, accurate interpretation of all datasets through advanced wireline log analysis to support field crews and help producers make confident, regulator-ready decisions across the full well lifecycle, from new completions through production to abandonment.
Working remotely from our central processing facility, our analysts deliver real-time support to field operations while preparing detailed, client-ready interpretations. Using proprietary in-house software optimized for Western Canadian wells, we transform complex data into high-resolution waveforms, spectrograms, playable audio files, 3D visualizations, and standard Canadian reporting formats.
How Our Log Analysis Process Works
Real-Time Data Acquisition & Quality Control — Secure streaming and immediate QC of logs from electric line, slickline, and fiber optic wireline operations across our full fleet.
Advanced Processing — Raw signals are processed into clear waveforms, full-spectrum frequency analysis, and intuitive visual displays.
Expert Interpretation — Experienced analysts apply decades of regional knowledge to integrate datasets and deliver precise results.
Rapid Deliverables — LAS files, annotated logs, PDF reports, and regulatory-compliant documentation tailored for AER, Saskatchewan, and BC requirements.
Specialized Interpretation Services
SCVF & Gas Migration (Well Abandonment) Analysis Advanced spectral noise logging, powered by our proprietary Casing Vibration Tool (CVT), delivers superior source identification for Surface Casing Vent Flow and Gas Migration. By capturing vibrations directly in the casing steel, we generate cleaner datasets with higher signal-to-noise ratio. These are processed into detailed spectrograms, full-well frequency analysis sets, and playable audio files that let you clearly “see” and “hear” gas movement, channeling, micro-annuli, and leak paths behind pipe. This precision minimizes failed squeezes, reduces rework, and accelerates compliant abandonment.
Cement Bond Logging Interpretation Detailed analysis of Cement Bond Logs (CBL), Variable Density Logs (VDL), and high-resolution radial cement maps to evaluate cement-to-casing and cement-to-formation bonding. Through advanced cased hole log interpretation, we can identify free pipe, micro-annuli, channeling, and zonal isolation quality, providing clear recommendations that support permanent plug and abandonment programs and full regulatory compliance.
Casing Inspection & Well Integrity Analysis High-resolution interpretation of Multi-Finger Caliper (MIT) and Magnetic Thickness Tool (MTT) data to assess internal and external casing condition. We map corrosion, pitting, wall thickness reduction, deformation, and wear using 3D imaging and full circumferential coverage, delivering critical insights for casing integrity management, risk assessment, and targeted remediation.
Formation Evaluation Comprehensive analysis of through-casing formation evaluation logs including the Cased Hole Analysis Tool (CHAT), Gamma Ray, Compensated Neutron (CNL), and Density measurements. Our Formation Evaluation also incorporates advanced neutron-based techniques, including analysis, providing a clearer understanding of fluid saturation and gas presence behind pipe. We accurately identify producing zones, gas storage behind pipe, fluid contacts, nuisance versus productive gas sources, and annular gas accumulation to support completion decisions, reservoir characterization, and precise barrier placement during abandonment.
Production Logging Analysis Expert evaluation of multi-phase flow profiles, spinner, pressure, temperature, density, capacitance, and noise data. We determine inflow/outflow contributions, leak paths, cross-flow, and overall well performance to support optimization decisions and accurate regulatory reporting.
Fiber Optic Sensing Interpretation Analysis of distributed temperature (DTS), distributed acoustic (DAS), and strain data for real-time monitoring. Applications include fracture monitoring during hydraulic fracturing operations, injection profiles for water/gas/CO₂ injection wells, completion diagnostics, production profiling, leak detection, and integrity verification.
Key Benefits
24/7 remote analyst support for field teams with rapid client deliverables
Superior visualization with spectrograms, audio playback, and 3D anomaly mapping
Reduced uncertainty and first-time-right outcomes on SCVF/GM and abandonment jobs • Seamless integration of all wireline logging datasets
Fast, Canada-specific deliverables fully aligned with AER Directive 020, Directive 080, ID 2003-01, Saskatchewan PNG015, and BC guidelines

Why Producers Across Western Canada Choose Reliance
Conventional log interpretation often misses subtle events due to fluid attenuation and waveform stacking. Our proprietary in-house processing and experienced 24/7 team overcome these limitations, delivering sharper, more reliable insights that help operators reduce inactive well inventories, meet provincial mandates, optimize production, and execute compliant abandonments — faster and more cost-effectively.
