Regulatory Compliance

During hydraulic fracturing operations, interwellbore communication can impact Identified Offset Wells (IOWs) located within the FPZ.

In Alberta, operators are required to monitor and mitigate these risks in accordance with:

• AER Directive 083

• Energy Safety Canada – IRP 24

Directive 083 requires licensees to maintain a documented well control plan for each at-risk offset well, including clear procedures outlining:

How pressure information is monitored and communicated to fracturing operations if interwellbore communication occurs.

GCI’s offset monitoring service is designed to support these requirements by providing:

• Continuous real-time pressure surveillance

• Automated alerts tied to defined pressure thresholds

• Secure data retention for post-operation compliance review

Why Monitor Offset Wells?

Many offset wells lack permanent instrumentation or reliable telemetry, making real-time pressure monitoring difficult during active completions.

Offset well monitoring allows operators to:

• Detect pressure communication early

• React immediately to unexpected pressure increases

• Reduce the risk of casing, tubing, or surface equipment failure

• Protect groundwater and surface infrastructure

• Demonstrate due diligence in the event of regulatory review

Beyond regulatory compliance, pressure data from offset wells provides valuable insight into:

• Fracture geometry and growth behavior

• Reservoir connectivity

• Stress shadow development

• Potential impacts on existing producers

This information supports faster post-frac decision-making and can reduce future downtime by identifying wells requiring early intervention.

Why GCI

Operators choose GCI because we focus on actionable pressure intelligence, not just raw data.

Our approach combines:

• Field-proven monitoring hardware

• Reliable real-time telemetry

• Clean, engineer-ready datasets

• Optional analytical support for interpretation

The result is faster operational response, stronger regulatory defensibility, and improved understanding of fracture behavior across the field.

Surface-Based DFIT Monitoring & Data Delivery

GCI Monitoring provides surface-based pressure monitoring for Diagnostic Fracture Injection Tests (DFITs), delivering high-resolution surface pressure data for independent engineering analysis. Our role is to accurately capture and deliver pressure data during injection, shut-in, and falloff, allowing operators and their engineers to perform DFIT interpretation using reliable, well-structured datasets.

GCI installs high-frequency surface pressure gauges at the wellhead, while the operator retains full control of pumping operations. During DFIT activities, we record continuous surface pressure data through injection and falloff, ensuring that pressure transients and decline behavior are captured with sufficient resolution for engineering evaluation.

All DFIT data is delivered in an easy-to-use format through GCI’s online dashboard and as downloadable files. This allows engineering teams to apply their preferred interpretation methods, workflows, and software tools without restriction, using data captured and delivered by GCI Monitoring.
