Pipeline Leak Location & Leak Detection

HGI specializes in detecting subsurface pipeline leaks using advanced geophysical techniques. Our services cover pipelines transporting water, sewage, oil, gas, and hazardous materials. Accurate leak detection is essential to prevent environmental damage, ensure regulatory compliance, and maintain pipeline integrity.

Importance of Leak Detection

Pipeline leaks can result from defects, damage, or aging infrastructure. Rapid and precise leak detection is vital to minimizing environmental impact, operational disruptions, and financial losses. Early detection helps prevent catastrophic failures, environmental contamination, and costly repairs, ensuring the longevity and safety of the pipeline infrastructure.

Advanced Leak Detection Methods

Time Domain Electromagnetic (TDEM) System

The Time Domain Electromagnetic (TDEM) method involves inducing electrical currents in subsurface conductors using electromagnetic waves generated on the surface. The depth of investigation is adjustable by varying the transmitter loop size, making TDEM suitable for a wide range of projects, from deep water-resource exploration to near-surface environmental applications.

Functionality: TDEM sends electromagnetic pulses into the ground and measures the response, which varies in the presence of leaks.

Usage: Highly mobile and suitable for large-scale surveys, often towed by an ATV. TDEM is effective for detecting leaks in pipelines located in remote or hard-to-access areas, providing comprehensive coverage quickly.

Electrical Resistivity

Electrical resistivity is a two-dimensional resistivity method that creates an image representing a slice of the earth. Electrical property contrasts are used to interpret differing geological or hydrogeological conditions.

Functionality: When a leak occurs, the electrical resistance in the surrounding soil changes, indicating potential leak points.

Usage: Ideal for detecting leaks in conductive environments, such as soils saturated with water or other conductive fluids. It provides detailed information on the location and extent of leaks.

Ground-Penetrating Radar (GPR)

GPR is a geophysical technique designed to image shallow soil and subsurface structures using electromagnetic (EM) waves, typically in the frequency range of 10-1000 MHz. GPR operates by emitting EM pulses into the ground and analyzing the reflections, similar to the principles of shallow seismic reflection surveys.

Functionality: GPR detects changes in material properties, such as moisture content, which may indicate a leak.

Usage: Effective in non-conductive environments and shallow depths. GPR is particularly useful for identifying leaks in pipelines buried under roads, pavements, or other hard surfaces without excavation.

How It Works: Data Presentation

HGI presents the data using electrical contour maps. These maps are color-coded to show regions of varying electrical resistance, with conductive areas indicating potential leaks. This method provides clear, visual identification of compromised sections, facilitating efficient and targeted repair efforts. The maps provide an intuitive and easy-to-understand representation of the survey results, aiding in quick decision-making and action.
