Built from thousands of feet of casing and tons of cement, comprehensive cased-hole well integrity raises questions that no single tool or measurement can answer. That’s why our SecureView service combines and overlaps measurements to detect any wellbore problem in one logging run.

An advanced, high-speed DC motor drives the scanning head—ranging from 3.38-in. (86-mm) to 10.5-in. (266.7-mm) outer diameter—�which enables precision transducer firing that minimizes the risk of missing critical details and improves accuracy. An ultrasonic transducer on both the scanning head and body provides 360° casing and cement coverage and identifies channels in the cement map as small as 5°. The patented mud chamber provides a continuous mud-property measurement that enables an accurate evaluation of the cement acoustic impedance.
BondView™ tool Short and lightweight cement bond tool for horizontal applications
Cement-to-casing bond assessment
Cement-to-formation bond assessment
Applications
Determine the quality and vertical length of the cement bond between your casing and the formation.

• Uses a monopole transmitter and 3-ft and 5-ft receivers to acquire amplitude, travel time, signature, and variable-density-log (VDL) measurements. • Suited for highly deviated wellbores in which centralization critical for accurate acoustic measurements—is difficult to maintain. • The short length and light weight help to eliminate problems associated with inadequate centralization.
FluxView™ tool Superior analysis of internal and external casing damage using 360° coverage magnetic flux technology
Determination of penetration percentage Geometry of internal and external casing defects Long-term, time-lapse corrosion monitoring
for storage and injection wells Evaluation of anticorrosion system effectiveness
Applications
Location and identification of casing hardware Evaluation of perforation performance Establishment of remediation requirements Identification of casing weight or grade change

Presentation Notes
• The 360° sensor array and advanced analysis techniques determine percent of defect penetration and evaluate casing geometry inside and outside the casing wall. • A powerful samarium-cobalt (SmCo5) magnet produces concentrated levels of magnetic flux in the casing wall. Within this magnetic field, localized disturbances �created by the casing defects cause magnetic flux to leak from the casing. The sensors evaluate the magnetic flux to pinpoint the location and extent of casing damage. • The tool response can be modeled for different casing sizes, weights, and grades use the Weatherford pipe library.

Presentation Notes
• The precision-calibrated feeler arms capture independent, radial measurements. • The 40-arm and 60-arm CalView tools capture 400 data samples per 3.2 ft (1 m), compared to the industry standard �of 40 samples. No other caliper tool on the market can deliver equivalent resolution at the same logging speeds. • The 60-arm tool can be modified to measure casing internal diameters up to 20 in. (508 mm) and can include a �high-pressure housing to raise its pressure rating to 30,000 psi (206.8 Mpa).

Initially client called in to log pipe integrity logs, but well had too high of h2s concentration for us to log. They ended up setting a plug and killing the well and squeezing off what they thought was a hole. They drilled out and called us out to log across where they had squeezed with urs, cbt, cit and msc. The combination of the logs explained what we were looking at. The caliper read the bit they had drilled out the cement with. The cit showed lack of metal due to parted connection. The urs showed that the caliper was reading cement, until it reached a channel which was confirmed by the msc and urs in combination. To summarize, without the cit, the cemented portion of the parted casing would not have been realized due to caliper reading bit.
Let’s shine a light on cased-hole well integrity.

As an industry, we don’t talk about well integrity enough. It’s what protects our assets and lets our crews go home to their families at night. We have invested years of research into a complete well-integrity evaluation. We think that this information, combined with an efficient remediation package, takes the bite out of well integrity unknowns, including cost.
