DETAILS 2 3/4″ Tool
The near receiver, located 3 ft from the transmitter, is constructed of an 8-sector radial receiver and a separate 3′ receiver. Each sector provides bond data covering a 45° section of casing. The primary 3′ amplitude is measured directly and does not rely on reconstructing the sectored data from the near receiver. The far receiver, located 5ft from the transmitter, generates a Variable Density Log. The RBT deploys in deviated holes and combines readily with any of the complete range of tools. Its slotted sleeve technology imparts sound isolation, rigidity and tool strength. The tool is comprised of corrosion resistant materials throughout.
Applications & Benefits
- Provide quantitative analysis of cement bond in eight 45 degrees segments for 360 degrees coverage around the borehole.
- Effectively identifies intervals of uniform bonding and detects cement channels or voids in casing sizes from 4.5 to 13.4 in
- Quantitative analysis of cement bond to casing
- Qualitative analysis of cement bond to formation
- Fully digital and combinable
DETAILS 1 11/16″ Tool
Much like the larger tool the near receiver, located 3 ft from the transmitter, is constructed of an 6-sector radial receiver and an independent 3′ receiver. Each sector provides bond data covering a 60° section of casing. The primary amplitude is constructed from radial signals at the near receiver. The far receiver, located 5ft from the transmitter, generates a Variable Density Log. This thru-tubing tool deploys in deviated holes and combines readily with any of the complete range of tools. Its slotted sleeve technology imparts sound isolation, rigidity and tool strength. The tool is comprised of corrosion resistant materials throughout.
Applications & Benefits
- Provide quantitative analysis of cement bond in six 60 degree segments for 360 degrees coverage around the borehole.
- Effectively identifies intervals of uniform bonding and detects cement channels or voids in casing sizes from 2.375″ to 7″
- Quantitative analysis of cement bond to casing
- Qualitative analysis of cement bond to formation
- Fully digital and combinable
