Radial Bond Tool

Category: Tags: , , , , ,




The Ultra High Speed Hybrid Radial (UHSHR ) tool evaluates the cement bond quality and integrity to both pipe and formation by providing the measurements of the cement bond amplitude (CBL) through near receiver (3-ft crystal ), and variable density log (VDL) through far receiver (5-ft Crystal). UHSRH tool also provide a cement map through six (eight) (twelve) segmented receivers, each segment covers 60° (45°) (60°) section of the pipe. All sonic data is captured and stored at 1µs sample rate digitally within 2ms after the transmitter fires allowing flexibility of the output telemetry. The UHSHR has a built in TOP SIDE LOCATOR (optional) which determines the top of the tool during logging. The telemetry can handle the Hybrid Memory / Real Time mode at the same time, the UHSHR can run as Combo with the Multifinger Caliper 40 or 56 arms, The data can be uplink in Real time at a high baud rate (100kbaud to 400kbaud), all the data is digitalized, transmitted and storage in 32 Gbytes of memory continuously over 18 hours. The tool be can run as standalone memory tool with slickline units. UHSRH runs with Scientific Data Systems panels and their software Warrior.
