VibmonThe VIBMON monitors downhole shock and vibration in three axes. Real-time telemetry and display of downhole shock and vibration enables drillers to avoid costly downhole equipment failure and optimize ROP. Data is also recorded downhole for plotting and analysis on surface.

Directional Interface ModuleThe XXT DIM provides a flexible, intelligent solution for the acquisition, formatting and telemetry of downhole data to surface. It is a drop-in downhole Directional Interface Module providing Mud Pulse Telemetry compatible with industry standard Tensor systems.

Directional Sensor ModuleThe XXT-DS Directional Sensor, designed to XXT standards and specifications, incorporates the industry renowned JAE accelerometers and magnetometers. Incorporating XXT’s Digital Head module, the complete Directional Sensor assembly provides a temperature corrected plug-and-play solution using the most reliable aviation specification components.

Pulser Driver & DC Drive PulserThe XXT-PDEM Pulser Driver and DC Drive Pulser is a rugged field proven unit with a highly efficient and reliable brushless DC motor. The intelligent PDEM electronics optimizes telemetry rates and manages power consumption using an accelerometer flow switch. The DC motor drive gives huge battery savings and higher MTBF than comparable solenoid based units whilst being easy to service.

AccessoriesEnteq manufactures a complete range of MWD and DD accessories including everything needed to run an MWD survey. Our South Houston product centre makes everything from spearpoints to mule shoes and all of the barrels and interconnects in between. We also supply larger accessories including the kit boxes, tools racks and pipe screens.

OptionsGamma Ray Sensor

An Industry standard, natural Gamma Ray tool based around a highly ruggedized scintillation counter and photomultiplier tube. The GR data can be used in depth correlation and geostreering applications where radioactive uranium is associated with gas rich shales.

EM System

The Enteq EM telemetry system provides high-speed electromagnetic uphole data transmission. The systems can be used standalone in shallow wells or where mud pulse telemetry is not appropriate. It can also be ran in combination with a pulser to provide added data security and increase real-time data bandwidth.

Resistivity Tool

Single and Multifrequency LWD tools available in a complete range of sizes including slim hole. These field proven tools deliver true reservoir saturation data from multiple depths of investigation. The wireline log quality output has been used by many major oil all over the world. The data can also be used for geostreering applications.

Enteq MWD System

The Enteq surface system is based around the xxMWD/PC program suite. This PC based solution offers a unique, feature rich range of programs and utilities to cover every MWD option. Advanced capabilities such as Dynamic Sequencing save operating time and optimize data throughput. The software runs on a ruggedized Laversab 4100 unit, which is fully rated to Class 1 DIv 2 specification. Within the 4100 enclosure sits the Enteq MPRx which utilizes XXT’s best-in-class decoding algorithms to receive and decode the telemetry pulses received from the standpipe’s pressure transmitter.. Robust hardware, filtering, and embedded firmware is used to remove mud pump and other undesirable noise, allowing the XXT downhole sensors to transmit data at maximum bit rates.
