Well Integrity & Production Logging
Surface Read-Out & Memory
Our production logging tools help efficiently and accurately evaluate your well's performance. You can configure these tools for optimal measurement of a wide range of production conditions, including vertical, highly deviated, or horizontal wells. Use them for a variety of well completion types, including openhole (barefoot), cased-hole, perforated, gravel-packed, or slotted-liner configurations.
All our production logging tools operate in memory or surface readout mode, and can combine effortlessly with well integrity and other tools
Our suite of well integrity products enable you to identify faults or defects in your downhole components and make pro-active decisions to perform remedial work and avoid unnecessary production disruptions or emergency interventions.

Casing Collar Locator (CCL)
A Casing Collar Locator (CCL) contains a coil and magnets that detect changes in metal thickness at casing collars. When the tool passes a collar, the magnetic flux is disrupted, which generates an electric signal. This signal is then amplified and recorded as a voltage spike, called a collar "kick". CCLs are used for depth control and depth correlation, and are an essential tool in cased hole e-line operations. They can also indicate line over speed when logging in heavy fluids.
Capacitance, Temperature, Flow (CTF)
The Capacitance/Temperature/Flow Flowmeter (CTF) combines three sensors—capacitance water holdup sensor, temperature sensor, and flowmeter—with a single electronics section to identify water entry into hydrocarbon flow, hydrocarbon/water interfaces in shut-in wells, and hydrocarbon entry into water.
The Flowmeter measures well fluid velocity using a turbine (spinner) impeller, the higher the fluid velocity, the faster the spinner rotates. Knowing the fluid velocity and tubing size, volumetric flowrate can be calculated. Spinner mechanical sections should be selected to suit completion size and fluid velocity. However in general, the largest spinner impeller that can be used will give the best results.
Caged Fullbore Flowmeter: The spinner impeller is closed in tubing and opens up in casing to present a large diameter impeller, giving high sensitivity. It is protected by a spring bow cage.
Jewelled Spinner: This spinner rotates continuously. It has jeweled bearings which give superior performance at very high fluid velocity and in wells with sand or solids polluting the well fluids (which can jam up roller bearings).
Caliper (24,40,60) Finger
When the Multifinger Imaging aka Multifinger Caliper tool (MIT) is run in hole, the fingers are closed to prevent damage. Once at logging depth, a motor is activated from the logging system or by the memory tool and the fingers open. A continuous measurement of Specifications the pipe’s surface condition is made as the tool is logged up. The tool has an inclinometer to indicate the finger positions relative to the high side of the pipe, so that features can be orientated correctly during data processing. MIT data can be used to generate 3D images of pipe condition
Magnetic Thickness Tool (MTT)
The Magnetic Thickness Tool (MTT) surveys variations in pipe metal thickness. Twelve sensors are mounted on the inside of a set of bow springs, allowing the tool to pass through tubing and log pipe sizes up to 7-in. casing. An alternating magnetic wave is emitted from the tool. This wave permeates through the casing wall and then travels a short distance along the outside before passing back through the wall and being detected by the sensors. The velocity and amplitude of the emitted wave are affected by the metal thickness, with thinner walls resulting in faster wave propagation and less attenuation. These differences are used to detect and quantify variations such as pitting and metal loss.
Fluid Density Inertial (FDI)
The Fluid Density Inertial (FDI) tool uses the inertial response characteristics of a vibrating tuning fork to determine the density of the wellbore fluid mixture. The FDI tool is a nonradioactive method of determining density that is unaffected by well deviation. The sensor comprises a stainless steel tuning fork that Specifications Accuracy is vibrated near its natural frequency of operation by a piezoceramic stack and control electronics in the upper section of the tool. The frequency and amplitude of vibration are used to determine the actual density of the fluid surrounding the fork. Optimum quantitative results will be achieved in liquid- liquid mixtures or in pure gas.
In-Line Spinner (ILS)
The In-Line Spinner (ILS) flowmeter is used as a back up flowmeter in conjunction with a CFS or CFB and when it is necessary to log in tubing and casing in one logging run. (combined with a fullbore flowmeter) Density Oil, water and gas have different densities. By measuring the overall density of the wellbore fluid the fraction or holdup of each phase can be calculated.
