 Press Releases

  • FORT WORTH, Texas – May 6, 2019Probe, a leading supplier of cased-hole logging and advanced monitoring technology to the global oil and gas and geothermal industries, today announced that it continues to make headway in offering its customers additional resources to dramatically increase their data logging capabilities through the adoption of its high-speed digital (HD) telemetry platform.

    Known as the HD Platform, an increasingly wider range of high-speed, highly configurable digital sensors play critical – and unique -roles in helping operators to log data much more efficiently. In addition to its range of Standard and Array Production logging tools, Probe has been focusing on cased-hole formation evaluation solutions:

    -The MAC 24™ Multi-arm Caliper Tool, which makes it possible to identify integrity problems, such as mineral deposition, corrosion, wear or mechanical deformation, inside a completion.

    -The RADii™ Segmented Bond Tool, which measures and maps the quality of cement behind casing in oil and gas wells.

    -The RAS™ Reservoir Analysis Sonde, a three-detector pulsed-neutron logging tool for measuring reservoir saturation using Sigma and Carbon-Oxygen techniques.

    -The Spectral Gamma-ray Tool, an evaluation tool that offers insight into the radioactivity and mineral composition of cased-hole formations. 

    More data gathered per well intervention

    “For years, the demand for logging tools that are highly configurable and capable of gathering high quality data more efficiently has continued to rise unabated, so we believe that continuing to expand our truly intelligent, effective formation evaluation solutions is critical to our customers’ success,” said Martin Barratt, VP Global Sales of Probe. “The HD Platform is the result of a concerted initiative to enhance our field-proven tools with the highest quality measurements in the industry.  By enabling fully combinable configurations, we are confident that Probe delivers on every front.  By employing HD Platform compatible logging tools, service providers can now acquire more data per run in every well intervention. This enables operators to meet key objectives with a minimal number of well entries, improving efficiency and reducing cost.”

    The HD Platform: what it is and how it gathers data more efficiently

    The new HD Platform consists of two parts:  an inter-tool communications bus and mono-conductor telemetry which is managed by the Telemetry Control Unit (TCU).  The inter-tool communications bus is a single wire bi-directional system that operates at 500kpbs, which is ample speed to accommodate many different combinations of logging tools. The controlling telemetry - or alternative memory tool - samples sensors at a rate of 50 times per second, allowing high data rate tools and, for example, multi-arm calipers to provide high vertical resolution. Commands and instructions are also sent to the sensors on the same single wire bus.

    The TCU handles all communications to surface.  This device controls the data collected by the tools below, and packages it for transmission to the surface system. It receives commands from the surface system via the fast downlink, and responds back to the surface, as necessary. 

    The TCU can be replaced by the Memory Logging Tool (MLT) allowing all HD sensors to be deployed on slickline and coil tubing, among others,

    The HD Platform is a modular design offering simple mechanical maintenance and supported by plug0in electronic boards. It is well suited to both conventional and remote environment operations.

    Looking ahead, as part of its continuing commitment to developing technologies that gather comprehensive data, Probe plans to integrate HD telemetry technology into all current and future cased-hole logging tools.

  • MAC: Multi-Arm Caliper Tools
    MAC Multi-Arm Caliper tools are electromechanical cased hole logging instruments that provide an accurate and detailed internal profile of the tubing, casing and completion assembly....

  • A multi-finger caliper log of the inside of a completion enables operators to cost effectively plan work-over and remedial operations, and to keep  historical records of the general condition of tubing and casing in order to assess any problems associated to corrosion, wear or mechanical deformation through the life of the well.

    A series of independent radial measurements provided by the caliper arms, also commonly referred to as “fingers”, yields a detailed image of the inspected well that can be presented in various formats, including a cross-section of the casing and a 3-dimensional, color-enhanced visualization for tubulars ranging from 1 ¾ -in. to 14-in. internal diameter.

    Probe MAC™ tools are available in 24, 40 and 60-finger configurations with an extended range of measurement, and are designed with a small diameter housing that allows them to traverse most completion restrictions. A precision machined calibration bowl ensures that each tool configuration delivers accurate and reliable data.

    As a MAC tool logs the internal profile of the completion, the actuation of each finger is converted to an individual electrical signal. The signal is converted into a calibrated radial measurement that is transmitted in a data frame that consists of a frame identifier, individual finger channels, electronics temperature data and a checksum, at a rate of 13 times per second. Directional data is acquired simultaneously and can also be included in the log presentation.

    MAC tool data can be acquired on a standard Warrior™ cased-hole logging panel to offer real-time plotting of downhole data, high-speed data transmission, data processing and vivid imaging of the inspected casing.

  • RADii Segmented Bond Tools
    Probe's RADii™ Segmented Cement Bond Tools accurately measure and map the quality of cement behind casing in oil and gas wells...

  • The RADii™ Segmented Cement Bond Tool uses a single ceramic transmitter, an eight or sixteen segment receiver at 3 ft. and a single receiver at 5 ft. spacing. The segmented receiver generates a cement map which enables identification of cement channeling, while the single receiver generates the traditional cement bond log (CBL) and a variable-density log (VDL).

    The ruggedized design of the RADii tool ensures consistently reliable and accurate operation in a wide range of environments. The oil-filled mandrels containing the transducers can be serviced individually, enabling significant time savings when the tool requires service. Ceramic transmitter and receivers enable the tool to withstand hostile high-temperature environments.

    Data from the receivers are digitized and stored in the tool’s internal memory before being sequentially transmitted to surface. An internal controller transmits 8 signals from the RADii receiver, a composite signal representing the sum of the eight RADii signals, the 5 ft. receiver signal and an internally generated calibration signal. 

    An optional temperature sensor can also be mounted close to the transmitter. The temperature log recorded while running in hole can be used to provide additional cement quality information.

    In addition, the tool can be combined with other tools, including Gamma Ray, Casing Collar Locator, Neutron and Compensated Neutron tools to provide a comprehensive behind-casing cement and formation evaluation analysis.
