Voyager
Modular Near-Bit Sub | The Closest Thing to The Bit
Need to know what is happening at the bit and not fifteen meters away from it?
Indispensable when approximation of the position of the bit is an invitation for failure, our modular near-bit sub, Voyager, provides measurements as close to the real-time position of the bit as possible. For example, geosteering around tight formations, long laterals, horizontal drilling, and, perhaps most critically, collision avoidance applications — all rely on factual data from the position directly behind the bit.
Equipped with high-resolution 16-bin azimuthal gamma readings, impressive battery longevity, and easy to service and repair design, Voyager near-bit sub truly thrives in applications when “close enough” gets you nowhere you want to be.
Key Features
Critical Data
High-Quality Data From at The Bit
With sensors positioned less than two feet behind the drill bit, Voyager near-bit sub provides the following data:
- Inc at Bit with impressive sensor accuracy range of 0.15°,
- Gamma at Bit, and
- High-Resolution 16-bin Azimuthal Gamma.
Ultimately, MWDPlanet ensures that your data is both high-quality and high-accuracy during your most critical applications.
Easy and Fast Service
Innovative Modular Pressure Housing Design
Voyager near-bit sub’s pressure housing safely protects the electronics inside and allows you to quickly replace the washed out sections. Typically, repair to near-bit subs is restricted by design constraints. Now, with our innovative modular design, damaged sections are easily replaced without needing to discard the entire sub.
In short, Voyager is built to enhance your directional drilling workflow for a long time.
Hours of Battery Capacity (4.5 API Regular)
Hours of Battery Capacity (3.5 API Regular)
Extended Battery Life
Our near-bit sub models boast impressive battery capacity: at least 200 hours more than competing subs! Due to our innovative pressure housing, Voyager is able to fit a higher quantity and quality of batteries. This is one of the many ways our design implementations prioritize reliability for our clients.
Easy to Integrate
Non-Interfering With Current Workflow
Voyager is designed to seamlessly integrate into existing fleet of MWD systems, even ones based on Tensor technology. And, since Voyager is an add-on sub, you have full control over which motor to use.
Data From Where It Is Needed Most
For applications when accuracy of bit position needs to have no compromises, our near-bit sub, Voyager, provides rich inclination and gamma data directly behind the bit. No matter how complicated the expedition, Voyager’s unobtrusive design will dependably deliver critical data.
