Muleshoe Assembly
Pulser Driver
Vibmon The 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 Module The 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 Module The 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 Pulser The 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.
Accessories Enteq 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.
Options Gamma 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.
