Drill Pipe Gauge Carrier
Our Drill Pipe Gauge Carrier technology was developed to meet the specific needs of a customer. The DPGC allows these ruggedised probes to be simultaneously run on drill pipe whilst retaining pump-through capability and high tension, compression and torque characteristics. This permits data collection without additional runs in hole or the need to mobilise a wireline intervention set-up and crew.This permits data collection without additional runs in hole, dramatically reducing not only operational and rig time costs but also the risk associated with increased crew numbers, had a separate wireline intervention been used.
The DPGC is a multi-functional memory logging tool designed to log gamma ray, CCL, fluid temperature and well pressure at up to 32 simultaneous samples/sec. The sensor tool is conveyed in the drill pipe gauge carrier and eliminates the requirement for an additional logging run.
The DPGC was developed by READ Cased Hole as a direct response to the specific needs of a client. It delivers a suite of ruggedized sensors that allows the operator to record fluid temperature, pressure, gamma ray and CCL response without the need to mobilise a wireline intervention setup and crew.
APPLICATIONS:
•Deployed to capture temperature profiles to verify formation models.
•Deployed to capture GR and CCL to verify completion depths to openhole GR Logs.
•Deployed to capture pressure profiles to verify integrity of completion.
BENEFITS
—Reduced costs without the requirement for Wireline Intervention
—Improved HSE without the requirement for Wireline Intervention
—No additional runs in hole required
—Verification of tally
—Verification if Liner Hanger set with GR Pip Tag
—Verification of temperature curve before perforating
—100% redundancy on each run ensures first class data integrity and reduced risk of NP

The READ Ruggedised CCL tool is a highly versatile precision correlation system used to determine the position of moving inserts within downhole completion devices.
An extremely robust memory and electronics permit the deployment of the tool in a carrier, run on Coiled Tubing or slick line, to deliver precision determination of depth and relative positions of complex assemblies. READ’s unique “fingerprint” library of completion devices enables precise and accurate interpretation of the data.
A high-resolution coil and magnet assembly responds to changing metal thickness and geometry in its vicinity, while the temperature and quartz pressure sensors in the tool can aid in diagnosing well production problems. The resulting signals are input to high sample-rate, programmable electronics and stored on high capacity memory.
Owing to its rugged construction the RCCL system has been designed to withstand hammering and jarring forces, often required during manipulation of completion items or the delivery of remedial products. The in-built bypass tube within the optional carrier system also facilitates pump-through capability for use on Coiled Tubing applications.
APPLICATIONS:
•Depth correlation in tubing and casing
•SSD position identification
•SSD flow verification/leak detection
BENEFITS
—Robust design
—Deployable on slickline or coiled tubing
—High density data storage
—Provides accurate temperature and quartz pressure data in same run
—Fast data sampling for more accurate results
—Downhole redundancy (2 short R-CCL tools may be run in the same carrier)
—Pump through facility for coiled tubing operations
