Introduction


The ComboLog-SM delivers the same, high-quality data you would expect to get from conventional tools, but with a much smaller 2.875-in. diameter in hostile envirement. Every Slim Combo logging tool is fully characterized, which means that you never have to choose between data fidelity and tool size. These tools provide the accuracy of traditional wireline logging. The Slim combo Logging system offers multiple conveyance options. Data can be acquired in real time when run on wireline, or it can be deployed by coiled tubing or drillpipe in memory mode. When it conveyed by drillpipe, it can be released by mechanical ball method or Timing control method.With Slim Combo logging services, you can easily achieve reliable logging in challenging applications with data quality you expect from conventional tools.OurSlim Combo logging tools are available for holes with diameters up to 12 in. Theyare environmentally corrected and fully characterized for:

The CCL-S Tool measurement is based upon the principle that a changing magnetic flux within the tool sensor coil generates a voltage across the terminals of that sensor coil. The magnetic field of a CCL-S magnet is affected by any magnetically sensitive material close to it, such as the casing in a borehole. A collar or joint in the casing changes the magnetic flux field including the flux passing through the sensor coil ends adjacent to the magnets,causing an electric voltage to be generated.

This tool is the downhole telemetry interface for GTS type tool. The primary function of the TSO-SM is to act as a repeater of the telemetry channels and to create the GTS tool Bus (GTS-IB).A secondary function is to acquire data from several sensors located in its electronic cartridge and outside of it. It can acquire the signal of natural gamma-ray spectralog, three orthogonal accelerometers and magnetometers, it can acquire the data from the downhole temperature/tension/mud resistivity.

The CNT-SM measures the hydrogen index of downhole formations. The measurements are converted to porosity values, which in combination with density tool measurements provide an indication of lithology and gas in zones of interest.The CNT-SM contains a radioactive source that bombards the formation with fast neutrons. The neutrons are slowed, primarily by hydrogen atoms in the formation. Detectors count the slowed neutrons deflected back to the tool. Because the CNT-SM responds primarily to the hydrogen content of the formation, the measurements are scaled in porosity units. The CNT-SM uses two thermal detectors to produce a borehole-compensated thermal neutron measurement.

The ZDT-SM measures formation density, photoelectric factor (a lithology indicator), borehole diameter with Decentralizer Sub(DCS-S). The density data are used to calculate porosity and determine the lithology. The combination of density and CNT-S data is used to indicate the presence of gas.The ZDT-SM has a gamma ray source and two detectors.Magnetics shielding and high-speed electronics ensure excellent measurement stability. It records the full-pulse-height gamma ray spectra from both detectors and processes them into windows. Bulk density and photoelectric factor are derived conventionally from the windows counts with enhanced quality control.

The DLT-SM tool measures formation resistivity and is designed primarily for use in boreholes filled with highly conductive drilling fluids. DLT-SM provides two resistivity measurements: a Shallow reading to investigate the formation near the borehole and a Deep reading to measure farther out where the formation is less disturbed by drilling fluids. These two readings are used to estimate the amount of hydrocarbon in a formation and the ease of recovering that hydrocarbon.

The tool provides the conductivity data necessary to estimate the effects of mud filtrate invasion and to resolve true formation resistivity. measurement recorded: Shallow Focused Laterolog

Detect and measure thin permeable beds in highly resistive formations

To aid in the interpretation of invasion profiles.

The Array Induction Tool-Slim Memory (AIT-SM) uses multi-spacing and multi-frequency measurements to acquire a complete set of data fromthe formations surrounding the borehole.The multi-spacing measurements allow improved conductivity measurements in complex environments. The short-spacing measurements (as short as 6-inch spacing) allow improved correction for borehole, rugosity and invasion effects. The long-spacing measurements (up to 94-inch spacing) are useful in deep invasion situations. The multiple-frequency measurements allow for an improved skin-effect correction and data quality checking. AIT-SM allows us to characterize invasion profiles, even in oil-based muds.

The Mass Isolator Sub-Slim (MIS-S) is designed as a substitute for long bridles on deep laterolog jobs.It has a standard 31-Pin connector and 9 feedthru wires. The pressure housing is comprised of a fiberglass substructure with an outer layer of rubber coating. The MIS-S should typically be located in the tool string below the cablehead.Two MIS-S are combined together to provide the necessary 24’ length of electrical isolation between the wireline armor of tool string housings, as required for the deep laterologs. The middle field joint of the assembled MIS-S’s serves as an SP sub and remote electrode.

The pressure housing is comprised of a metal substructure with an outer layer of fiberglass insulation material. Electrical mass isolation occurs in a specially designed bottom sub. The ISS-S should typically be located in the tool string upper the Dual Laterallog Tool-Slim Electronics and below the Micro Spherical Focused Laterolog Tool-Slim electronics.

The Swivel Assembly allows different portions of the tool string to rotate independently.It allows unrestricted 360°rotation by means of an internal slip-ring assemblyA swivel isolates an tool from the normal torque induced as the spiral-wound wireline is lowered into and pulled out of the well. This torque causes the tool string to rotatslowly-typically one or two rotations per 100 ft. (30) of depth for a seasoned line. Typically, this rotation does not cause any problems.

Introduction


ApplicationsAvoid the tool rotation when the cable is rotating, and enhance the reliability.

Reduce the risk of cable head and tool string tripping when long tool strings connect.
