Single phase (PLT) and Horizontal Production Logging Services (HPLT)

Production logging tools are run in completed wells to ascertain the nature and behavior of fluids in or around the borehole during production or injection. These logs are used to analyze dynamic well performance and the productivity or infectivity of different zones to diagnose problem wells, or to monitor results of a stimulation or completion.

  • Fluid Density Radioactive (FDR)
  • Capacitance Array Tool (CAT)
  • Production Dual Caliper (PDC)
  • The Orientation Tool (ORT)
  • Acoustic Fluid Identification Tool (AFI)
  • 1 11/16” Quartz Gauge Temperature
  • Production Logging Gamma Ray (PGR)
  • Reservoir Solution Logging (RSL) SIGMA/CO (carbon-oxygen logging)
  • Spinner Array Tool (SAT)
  • Fluid Density Radioactive (FDR)
  • This tool uses low energy gamma rays to determine the downhole fluid density during a production log. It provides a very reliable measurement, unaffected by well deviation and flow rates. Gamma rays are emitted from an Ameicium-241 at one end of measuring cell and are detected at the opposite end by a scintillation detector and photomultiplier. Well fluid flows through the cell and attenuates the received count rate in inverse logarithmic function of the average fluid density. The detector is temperature stabilized and matched to the gamma energy of the source.

  • Capacitance Array Tool (CAT)
  • Identifies fluid phase circumferentially around the wellbore. Oil, gas, and water have different dielectric constants and the CAT uses this property to identify fluid phases in high deviation and horizontal wells. An array of 12 miniature sensors is mounted on the inside of a set of collapsible bowstrings. They measure the capacitance of the surrounding fluid close to the well casing. All 12 values are simultaneously transmitted to the surface or into a memory section. Taking measurements in a single plane across the diameter of the wellbore rather than along it, results in an accurate cross-sectional plot of fluid phases. Combined with data from the SAT and the RSL, the tool allows quantitative estimates of the volumetric flow rate for each phase.

  • Production Dual Caliper (PDC)
  • The PDC has a pair of caliper arm mechanisms set at 90 ° to each other for measuring the inside casing diameter in the X & Y axes. It is fully collapsible down to tool diameter for funning into and pulling out of the hole.
    The PDC is spring-loaded and follows tubing ID while running in hole. It opens fully on leaving the tubing to enter the casing. Each arm operates as an independent unit exerting a constant radial force in any casing diameter.

  • The Orientation Tool (ORT)
  • The ORT uses highly sensitive magnetometers and accelerometers to provide accurate borehole measurements (azimuthal, deviation and relative bearing information)

    • Directional package for orientation and dip analysis
    • Fast Z acceleration for depth correction in analysis software
    • Easy to transport – less than 10 ft tool length
    • Fully compatible with Ultrawire tools
    • Operates up to 302ºF
  • Acoustic Fluid Identification Tool (AFI)
  • The AFI tool uses the characteristics of a vibrating tuning fork to determine the density of wellbore fluid mixtures. The tool is non-radioactive and is used to determine density in the wellbore. The industrial tuning fork sensor is routinely used in multiple production related applications. The amplitude and frequency of vibration is used to determine the density and viscosity of the fluid within the surrounding area of the fork and the operation is unaffected by well deviation. Excellent results can be achieved in liquid-liquid or pure has environments.

  • 1 11/16” Quartz Gauge Temperature
  • The Quartz Gauge Temperature Tool contains a highly stable and accurate quartz pressure sensor, combined with an external temperature sensor, to give the customer concise and accurate downhole data for use in production control and pressure transient analysis

    • Production Logging FlowMeter Spinners
    • Flowmeter Spinners provide flow measurements downhole. APC offers caged both caged fullbore and continuous spinners, both of which are run at the bottom of a production logging tool string to monitor downhole fluid flow rates. The caged fullbore spinner assembly collapses down to tool diameter, enabling it to pass through tubing restrictions, while the continuous spinner continues to measure flow rate through tubing.

    • Fullbore Flowmeters (CFBM)
    • Caged Fullbore Flowmeters (CFBM) have a spring-loaded cage that centers the spinner in the middle of the flow and supports tool weight in deviated wells. CFBM comes in two versions 3 arms & 6 arms. A large diameter impeller measures flow rates with coverage across the full bore of the casing. The spinner runs on precision roller bearings and its rotation is sensed by zero drag Hall-effect sensors. The signal from the sensors is converted into a flow rate measurement. The low mechanical threshold of these spinners enables them to be used in low flow rates; normal output is 10 pulses per revolution with directional indication. APC offers both 3 arm and 6 arm CFBM.

    • Continuous Flowmeters (CFJM & CFSM)
    • The continous flowmeters either have jewelled bearings (CFJM) or roller bearings (CFSM). The Jewelled bearing flowmeters typically have bettwe (lower) thresholds, while the roller bearing flowmeters are a little easier to maintain. Additionally, some contionous flowmeters have a ported shroud, which may make them less likely to trap debris. APC offers both CFJM & CFSM.

    • Capacitance Temperature Flowmeter (CTF)
    • The CTF combines three sensors – capacitance water holdup, temperature and flowmeter. Consequently all three measurements are taken from the same depth in the well, unlike the sensors on a standard PL string that are a much greater distance apart. Interchangeable spinner mecahnical sections are fitted to the bottom of the CTF- dual magnets and Hall effect sensors detect the rotation of the impeller . The signal response is converted by the flowmeter electronics, within the CTF and output as spinner velocity.

Reservoir Saturation Logging Services (RSL)

Each reservoir presents unique parameters and challenges in optimization. APC’s Reservoir Saturation Logging Services (RSL) is configured using a gamut of production logging sensors and state-of-the art pulsed-neutron sensors. The production logging sensors accurately describe the wellbore environment and performance. This data is enfolded in the pulsed-neutron workflow for characterization and interpretation of the reservoir parameters. This combination of sensors creates a comprehensive data set, thus providing a complete solution for reservoir characterization.

Cased Hole Formation Resistivity (TCFR)

With our Casing Formation Resistivity Tool (TCFR), APC provides deep-reading resistivity measurement behind steel casing. TCFR’s enhanced hardware and design brings improved operational efficiency. The tool injects a current that travels up and down the casing before returning to a return electrode. While most of the current remains in the casing, a very small portion gets into the formation. Specially designed electrodes measure the Nano-voltage difference created by this leaked current, and that difference is proportional to the formation conductivity. TCFR has many applications and uses, such as primary formation & evaluation in cased hole, monitoring of gas, oil and water contacts, re-evaluation of reservoir saturation, identify shallow gas, water injection status evaluation and detection & evaluation of bypassed hydrocarbons.

Cement Evaluation Services

Early Cement Bond Log (CBL) designs (1960s) used a single transmitter and single receiver for an amplitude measurement. In an evolution similar to that of open-hole acoustic logs, new designs were subsequently introduced that measured signal amplitude at a near receiver and a full waveform from a far receiver. Eventually, borehole-compensated devices using dual transmitters and dual receivers were introduced in the 1980s, and today most commercial devices use multiple transmitters and receivers in a variety of arrangements to provide compensated measurements.

  • Cement Bond Tools (CBT)
  • The Cement Bond Tool (CBT) uses a single acoustic transmitter and dual acoustic receivers spaced at 3ft. and 5ft. to accurately measure the quality of the cement job in a cased-hole environment. This tool uses an oil filled mandrel and all ceramic transducers to withstand the hostile environment of the well bore and provide good stability over the operating range of the tool.

    • 1 11/16" Cement Bond Tool
    • 1 11/16" Digital Cement Bond Tool
    • 2 3/4" Digital Cement Bond Tool
  • Cement Bond Logs (CBL)
  • Presentation of the full acoustic waveform assists in resolving bond ambiguities arising from use of an amplitude measurement alone and provides qualitative information about the cement-to-formation bond.

    Waveform displays may be in:

    • Variable density (VDL) or intensity (also called micro seismograms) formats
    • Oscilloscope waves (also known as x-y or "signature")

    APC provides VDL (Variable Density Logs) with the CBT. Variable density is a continuous-depth time display of full-waveform amplitude presented as shades of black and white. Positive waveform amplitudes are shown as dark bands and negative amplitudes as gray or white bands; contrast is proportional to amplitude. On a variable-density log, free pipe and fluid arrivals (if present) are easily identified as straight dark and light lines (indicating homogenous acoustic properties) at either side of the display.

Radial Cement Evaluation

Radial-cement-evaluation devices were developed to overcome some limitations of conventional cement-bond tools and to permit more accurate evaluation of cement distribution behind casing by providing the precise location of partial bond and channeling. These tools use one or more azimuthally sensitive transducers to evaluate cement quality around the circumference of the casing. Data from these tools are presented as individual log curves or as azimuthal images ("maps") of cement quality generated by interpolating between the individual azimuthal measurements. In addition, each tool design also provides a conventional 5-ft VDL waveform measurement to provide information about the cement-to-formation bond.

  • 2 3/4" Dual Receiver Cement Bond Tool
  • 2 3/4" Dual Receiver Cement Bond Tool + Temperature
  • 3 1/2" Dual Receiver Cement Mapping Tool

Corrosion Evaluation Logging Services

Reduce cost throughout the life of your well with corrosion control: it’s been estimated that at least 1% of the total operating costs of the petroleum industry could be saved by the correct application of existing corrosion protection technology. Corrosion evaluation and control are particularly cost effective for deep or remote wells, wells expected to have a long lifetime, and wells producing CO2 or H2S.

Because downhole corrosion problems are many and varied, we provide a variety of measurements—acoustic, electrical, and mechanical—to identify and quantify corrosion, determine the cause, and monitor, including evaluating the effectiveness of anticorrosion measures.

  • Multifinger Caliper Logging (MFCL)
  • Multi-Finger Caliper tools (internal casing and tubing corrosion evaluation) provide direct, accurate and reliable measurements of internal tubing and casing diameters. Used in both drilling and production environments, applications include the evaluation of corrosion, erosion, wear, bending, buckling, pits, holes and other defects with high accuracy.

    The Multi-Finger Caliper may also be used to measure the buildup of scale, paraffin or other mineral deposits in the wellbore. Auxiliary measurements include an integral wellbore temperature probe, along with deviation and azimuth information. Measuring fingers move radially along the inner casing or tubing wall, detecting any diameter change. This produces a high-resolution record of the tubular geometry, which can be viewed and presented as a conventional log, a cross section, or a 3-D color enhanced image. A range of instrument diameters with different finger arrays are available to provide optimized measurements in tubulars ranging from 1 7/8" to 13 3/8" diameter.

  • Multi- barrier Electromagnetic Telescope Corrosion Evaluation
  • The multi-barrier corrosion-logging tool is a new-generation tool that allows evaluating technical condition of the tubing and 3 casing strings (or 4 casing strings without tubing) simultaneously. The tool has fast response oils that generate electro-magnetic pulses. The speed of decay for these pulses is directly correlated to the pipe thickness and with the use of post-processing, individual pipe thickness responses are determined.

Noise and Leak Detection

APC’s Well Integrity Platform is being built to address the ever changing oil and gas market and its need for high quality services. Our range of memory logging services addresses the full well lifecycle and provides operators with tool packages to assist in the critical decision making process of well optimization.

Applications include: fluid breakthrough identification, injection and production profiling, stimulation and fracture flow evaluation and formation pressure determination behind multiple casings.

Tubing or casing leaks disturb the temperature profile and generate noise in a wide frequency range. These two phenomena’s can be jointly analyzed for leak location, origin and even rate.

Cement Dump Bailer

APC’s dump bailers are gravity-activated systems. This simple, yet effective, design is the most common type of system used in the industry. Cement is simply poured into the dump bailer. A glass rupture disc at the bottom of the chambers holds the cement inside the tool. Once above the bridge plug, the glass disc is broken and the cement, under the influence of gravity, falls freely onto the plug. Options are also available for heavy-duty top section windows. These provide extra support for long dump bailer tool strings at the filler window, which is the weakest part of the string. Two types of activation systems are available from APC. A small blasting cap can be placed on top of the glass rupture disc and actuated when required. The other method uses a mechanical striker pin. When the dump bailer hits a bridge plug with force, the pin strikes the glass disc rupturing it.

Isolation Packers

The packer forms the basis of the cased-hole completion design. The packer is a sealing device that isolates and contains produced fluids and pressures within the wellbore to protect the casing and other formations above or below the producing zone. This is essential to the basic functioning of most wells.

  • Retrievable Isolation Packers
  • The retrievable packer can be very basic for low pressure/low temperature (LP/LT) applications or very complex in high pressure/high temperature (HP/HT) applications. Because of this design complexity in high-end tools, a retrievable packer offering performance levels similar to those of a permanent packer will invariably cost more. However, the ease of removing the packer from the wellbore as well as features, such as reset-ability and being able to reuse the packer often may outweigh the added cost.

  • Permanent Isolation Packers
  • Permanent packers can be removed from the wellbore only by milling. The retrievable packer may or may not be resettable, but removal from the wellbore normally does not require milling., retrieval is usually accomplished by some form of tubing manipulation; this may necessitate rotation or require pulling tension on the tubing string. The permanent packer is fairly simple and generally offers higher performance in both temperature and pressure ratings than does the retrievable packer. In most instances, it has a smaller outside diameter (OD), offering greater running clearance inside the casing string than do retrievable packers. The smaller OD and the compact design of the permanent packer help the tool negotiate through tight spots and deviations in the wellbore. The permanent packer also offers the largest inside diameter (ID) to make it compatible with larger-diameter tubing strings and monobore completions.

Perforation Services

APC’s expendable Hollow Carrier Gun Systems are designed to run on wireline, tubing-conveyed or coiled tubing operations. All explosive parts designed are optimized for the best possible perforation performance. DPEX energetic Liner, Deep Penetrating Shaped Charges, Big Hole Shaped Charges and Good Hole Shaped Charges are available if a high degree of flexibility is required.

  • No Debris Gun System (NDG)
  • APC has acquired a new type of perforating gun to overcome the problems of unwanted debris in a well. This No Debris Gun System (NDG) leaves no debris in the well – and uses standard steel-case shaped charges. Special or exclusively dedicated shaped charges can be designed, optimized and manufactured at a customer’s request.

  • Booster Kit Slimline
  • Our booster transfer system provides an innovative method for ensuring the reliable detonation of perforating guns run in tandem. It includes a unique upper booster retainer that has a spring, which pushes the booster as close as possible to the lower booster retainer. This ensures a reliable transfer by closely aligning the bi-directional boosters end to end and by reducing the likelihood of debris falling between the boosters during operation.

    This booster Kit is used with Expandable Retrievable Hollow Carrier Guns from 40mm (1 1/16”) to 51mm (2”).
