Description

Vigor's Memory Cement Bond Tool is specifically designed to assess the integrity of the cement bond between the casing and the formation. It accomplishes this by measuring the cement bond amplitude (CBL) using near receivers positioned at both 2-ft and 3-ft intervals.

Additionally, it utilizes a far receiver at a distance of 5-ft to obtain the variable density log (VDL) measurements. To ensure a comprehensive evaluation, the tool divides the analysis into 8 angular segments, with each segment covering a 45° section.

This enables a thorough 360° assessment of the cement bond's integrity, providing valuable insights into its quality.

For those seeking customized solutions, we also offer an optional compensated sonic Cement Bond Tool.

Vigor's Memory Cement Bond Tool can be tailored to meet specific requirements and boasts a compact structure design, resulting in a shorter overall length of the tool string. Such characteristics make it particularly suitable for memory logging applications.

How Does Memory Cement Bond Tool (MCBT) Work?

Memory Cement Bond Tool (MCBT) accomplishes this by measuring the cement bond amplitude (CBL) using near receivers positioned at both 2-ft and 3-ft intervals. Additionally, it utilizes a far receiver at a distance of 5-ft to obtain the variable density log (VDL) measurements.

Features Of Memory Cement Bond Tool (MCBT)

①13-core quick change sub design

This feature allows for easy connectivity with other logging tools,which is crucial in creating comprehensive logging suites that can gather multiple data types in a single run.

②Integrated sensor

The tool combines gamma ray, Casing Collar Locator (CCL), and temperature sensors into a single unit. This integration allows for simultaneous data collection of multiple parameters:

- Gamma ray: Measures natural radioactivity of formations

- CCL: Identifies casing joints and depth correlation

- Temperature: Monitors wellbore temperature variations

③Post-logging calibration

The ability to calibrate after logging is completed enhances data accuracy. It allows for adjustments based on actual downhole conditions experienced during the logging run, potentially improving the interpretation of results.

④Inclination and relative azimuth measurement

This feature provides information about the tool's orientation in the wellbore, which is crucial for accurate data interpretation, especially in deviated or horizontal wells. It helps in understanding the tool's position relative to the wellbore and formation.

⑤Independent sensor structure

The sensors are designed as separate, modular units. This design improves reliability as individual sensors can be replaced or maintained without affecting the entire tool. It also simplifies maintenance procedures and potentially reduces downtime.

⑥Versatile deployment options

The tool can be run through various conveyance methods including drill pipe, tubing, slickline, or wireline. This flexibility is particularly valuable in highly deviated and horizontal wells where traditional wireline logging might be challenging or impossible.

⑦Large data storage capacity

With 10G bits of memory, the tool can store vast amounts of data. This is crucial for memory logging tools that need to record all data downhole for later retrieval.

⑧High-speed data acquisition

The 320ms acquisition frequency allows for very detailed logging, capturing rapid changes in wellbore conditions. This high resolution can be crucial for identifying small-scale features in the cement bond or formation.

⑨Fast data reading

The ability to read data at over 10Mb/s after logging significantly reduces the time required to download and begin analyzing the logged data once the tool is retrieved.

⑩ Extended logging duration

The large storage capacity allows for over 200 hours of continuous logging. This is particularly useful in long horizontal sections or when multiple logging passes are required.

⑪Operational efficiencies

The last three points highlight the operational benefits:

- Field labor saving: Fewer personnel may be required to operate the tool.

- Project time saving: The tool's efficiency can reduce overall project duration.

- Less equipment: The integrated nature of the tool and its versatility mean fewer separate tools or equipment pieces are needed on site.
