ComboLog-Memory Applications Reservoir delineation Hydrocarbon saturation determination and imaging Movable hydrocarbon determination Location of porous and permeable zones Gas detection Lithology determination Well-to-well correlation Thin-bed analysis
Introduction ComboLog is more cost effective to run because it requires significantly less rig time. The ComboLog system is less than half as long as conventional tools and weighs about half as much, yet it gives you better, quicker and more accurate answers—both in memory and real time. When ComboLog works in memory mode,It can provide wireline-quality openhole logs without wireline. The tool string is powered by a battery sub, and data are stored in nonvolatile memory chips housed in a memory sub. Log values are recorded in time-base and converted to depth logs when the string is recovered at the surface. Using drill pipe conveyance methods, ComboLog enables fast and efficient logging in highly deviated wells and in horizontal wells with challenging hole conditions.
Benefits Less rathole needed for the shorter length, lowering drilling time and cost More reliable performance for reduced downtime, which saves rig time Better quality logs, more data and higher resolution, revealing hard-to-find pay zones Fifty percent reduction in time spent on location, significantly lowering operating costs Short-radius wells readily logged
Features Overall length greatly reduced through the use of integrated sensors and reengineering Speed correction Integrated Rxo measurement Depth matching and borehole correction

Tool String
Swivel Sub (SWS) Applications Different portions of the tool string to rotate independently Unrestricted 360° rotation by means of an internal slip-ring assembly
Introduction The SWS Swivel Assembly allows different portions of the tool string to rotate independently. It allows unrestricted 360° rotation by means of an internal slip-ring assembly. A 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 rotate slowly — typically one or two rotations per 100 ft. (30 m) of depth for a seasoned line. Typically, this rotation does not cause any problems.

Casing Collar Locator (CCL) Applications Depth Measurement
Introduction The CCL tool measurement is based upon the principle that a changing magnetic flux within the instruments sensor coil generates a voltage across the terminals of that sensor coil. The magnetic field of a CCL 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.

Compensated Neutron Tool-Memory (CNT-M) Applications Indicate formation porosity in open or cased boreholes. Dividing reservoir. Distinguish gas reservoir.
Introduction The CNT-M 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-M 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-M responds primarily to the hydrogen content of the formation, the measurements are scaled in porosity units. The CNT-M uses two thermal detectors to produce a borehole-compensated thermal neutron measurement.

ComboLog-Memory Applications Reservoir delineation Hydrocarbon saturation determination and imaging Movable hydrocarbon determination Location of porous and permeable zones Gas detection Lithology determination Well-to-well correlation Thin-bed analysis
Introduction ComboLog is more cost effective to run because it requires significantly less rig time. The ComboLog system is less than half as long as conventional tools and weighs about half as much, yet it gives you better, quicker and more accurate answers—both in memory and real time. When ComboLog works in memory mode,It can provide wireline-quality openhole logs without wireline. The tool string is powered by a battery sub, and data are stored in nonvolatile memory chips housed in a memory sub. Log values are recorded in time-base and converted to depth logs when the string is recovered at the surface. Using drill pipe conveyance methods, ComboLog enables fast and efficient logging in highly deviated wells and in horizontal wells with challenging hole conditions.
Benefits Less rathole needed for the shorter length, lowering drilling time and cost More reliable performance for reduced downtime, which saves rig time Better quality logs, more data and higher resolution, revealing hard-to-find pay zones Fifty percent reduction in time spent on location, significantly lowering operating costs Short-radius wells readily logged
Features Overall length greatly reduced through the use of integrated sensors and reengineering Speed correction Integrated Rxo measurement Depth matching and borehole correction

Combo Logging system (ComboLog) Introduction The PI Combo Logging System incorporate the latest digital capabilities in their sensor, mechanical, and electrical architectures; rendering toolstrings that are significantly shorter, lighter, without penalty in temperature or pressure ratings. It is more cost effective, requiring significantly less rig time. You’ll increase your logging efficiency with reduced set-up and calibration time, and faster turn around on wellsite processing. The toolstring expands the traditional resistivity and porosity measurements. Tool movement is measured for real-time speed correction and depth matching.
