Cased Hole Logging

Empire Wireline Services is synonymous with precision and expertise in the field of Cased Hole Logging. With over 100 years of cumulative experience, we are committed to providing unparalleled cased hole logging services that maximize wellbore integrity and optimize production. Our suite of advanced tools and logging capabilities are designed to meet the highest industry standards, ensuring our clients receive accurate and actionable data every time.

What is Cased Hole Logging?

Cased Hole Logging is a crucial process conducted in wells that have already been cased with steel casing. Unlike open hole logging, which is performed before the casing is set, cased hole logging provides vital information about the well’s integrity, production efficiency, and formation properties after the casing has been installed. This process involves deploying various tools to measure parameters such as cement bond quality, casing integrity, fluid saturation, and temperature.

Empire Wireline’s Cased Hole Logging Services

Multi-Finger Caliper (MFC)

Empire Wireline’s Multi-Finger Caliper (MFC) is a state-of-the-art device featuring 24 to 60 high-resolution calipers to measure the internal radii of wellbore tubing and casing. This tool provides meticulous measurements for pipes ranging from 1.75 inches to 20 inches in diameter, helping to identify deformation, corrosion, and scale buildup.

Electromagnetic Thickness Tool (EMT)

Our Electromagnetic Thickness Tool (EMT) offers a non-invasive method for assessing both inner and outer casing integrity. By measuring the phase shift of an induced electromagnetic field, the EMT detects the extent of corrosion and remaining wall thickness, providing a comprehensive evaluation in a single trip down the well.

Cement Bond Log (CBL)

Empire Wireline employs advanced Cement Bond Logging tools to evaluate the quality of cement between the casing and the wellbore formation. Our Cement Bond Tool (CBT) captures high-resolution data to ensure proper zonal isolation, essential for preventing fluid migration and optimizing well performance.

Spectral Noise Tool (NST)

The Spectral Noise Tool (NST) is integral for detecting leaks, channeling, and flow anomalies within the wellbore. By analyzing the frequency spectrum of noises generated by different sources, this tool can locate production intervals and evaluate fluid dynamics, enhancing overall well productivity.

Pulsed Neutron Tool (PNT)

Our Pulsed Neutron Tool (PNT) measures formation porosity and water saturation behind the casing. It captures data on thermal neutron decay, providing critical insights into remaining hydrocarbons, identification of bypassed zones, and differentiating between oil, water, and gas.
