Our XACT acoustic network is designed to help you make different decisions for realizing your well’s potential.

Our platform is powerful, easy to use and seamlessly integrates into existing drilling and completion operations. Our network of tools and associated on-site equipment and support offer a comprehensive virtual view of the entire wellbore and drill string, by transmitting measurements and other downhole data in real-time. Scroll down or click here to learn more.

The key components of the network are distributed downhole measurement nodes. A collar-based design provides space for batteries, sensors, electronic boards, and the piezoelectric stack that transmits the data. Physical parameters such as pressure, weight and temperature are transmitted to surface acoustically via standard drill pipe.

The nodes are handled like drill pipe and use the same threads as the drill pipe tool joints. They are spaced at predetermined locations within the drill string (usually about 5,000 feet apart in vertical sections and 3,000 feet apart in lateral sections) to provide optimum signal strength and transmission range depending upon the angle of the hole. All the nodes have open through-bores. This allows for deployment of wireline conveyed tools as well as wiper darts and third-party tool activation balls, without restricting flow during drilling or completion operations.

The nodes function as voltage charges sent across their piezoelectric stacks generate an acoustic signal that is transmitted up the drill string via the wall of the drill pipe in real time. This signal carries the associated measurement data.

Once the acoustic signal reaches the surface, it is captured and transmitted wirelessly to an onsite computer by XACT’s patented C1D1-rated Electronic Acoustic Receiver (aptly abbreviated EAR).

The EAR is attached to the top drive, frac head, cement head, etc. Repeater nodes along the string not only act as signal boosters, but also are capable of taking measurements independent of each other.

Measurements of weight, torque, pressure, bending, and other physical conditions are displayed. They are output via WITS onto the rig and client networks.

They are also ported to a highly secured server and web-based visualization service. This allows for remote viewing of the data at well sites, offices, and real-time operating centers (RTOCs) anywhere in the world in a matter of seconds.

The decoded data is available via a number of visualization options. A graphic format presents even small changes in the downhole environment such as weight, torque and annular pressure along the wellbore. Data can be transmitted to the surface in real time, and/or held in memory until tripped out of the hole—providing along-string measurement and logging of downhole events. Also, data can be easily integrated with other data streams for improved downhole insights. The network is configurable to client needs to balance between essential update rates, battery life and other considerations.

XACT’s acoustic technology platform operates in virtually any drilling or completions environment as it is independent of fluid type and isn’t restricted by circulation rate or high-resistivity formations.

This makes the network an ideal option for monitoring downhole dynamics during critical well construction operations such as completions, liner running, and cementing; pressure data visibility in under-balance drilling; or managed-pressure drilling, during well control, tripping, and other no-flow operations among many other applications.

The balance of  Capability and Simplicity makes XACT’s Acoustic Telemetry Network a fit-for-purpose tool for many well construction operations.
