LWD Solutions

 

AtBit

Enteq and WRT (Well Resolutions Technology) have collaborated to provide seamless MWD plus integrated AtBit solutions that will provide directional drillers with real-time access to critical AtBit data for improved drilling operations and faster steering decisions.

AtBit Gamma

The PayzoneTracker is the latest generation of at-bit tool system. The PayzoneTracker is the latest generation of at-bit tool system designed and developed for placement of long laterals in shales or thinnly bedded payzones.

Unlike MWD and/or LWD tools that usually are tens of feet behind the bit, the PayzoneTracker brings sensors as close as12 to16inch behind the bit, allowing well trajectory adjustments to be made hours earlier.

AtBit Resitivity

The GeoTracker tool delivers, for the first time, compensated propagation resistivity measurement at or near the bit. With the patented side-mounted antennas, the tool provides 16 sectors of attenuation andphase-shift measurements from a rotating BHA.

The depths of investigation of the measurements range from a few inches to 30 inches.The tool may be run either below a motor, right above a rotary steerablesystem (RSS), or as part of an RSS.

When run below a motor, the measure point is as close as 12 inches from the bit.

EM short-hop is available for transmitting the data across the motor to the MWD system. Like traditional propagation resistivity tools, the GeoTracker tool works in almost all kinds of mud.

PowerHop Wireless Power & Data Dowhole Connectivity

Seamlessly and without anyconnection wires, integrates any 3rd party collar based resistivity, LWD sensor or device to a retrievable standard bottom mount pulser MWD string, enabling a simple, safe and efficient rig-up.

The Powerhop provides precision Pipe / Annulus pressure, gamma and continuous inclination at the top of the drilling motor.

For power efficiency and to extend battery life, the PowerHop and LWD sensors are powered up, measurements taken and powered back down in under 0.03 seconds.

Resistivity Solutions

Boundary Tracker

A new generation of LWD azimuthal resistivity tool. It provides both deep-reading propagation andazimuthal resistivity measurements for well placement andformation evaluation.

The tool is designed to run with low-speed MWD systems with data telemetry rates around 1 BPS.

The tool can be run above either an RSS or a motor. When run above an RSS, the tool offers two fully independent sets of azimuthal resistivity measurements, thus increasing the measurementreliability.

When run above a motor, the tool offers a unique feature of continuous boundary tracking, even in a sliding mode.

Tracker Express

A new class of LWD azimuthal resistivity tool that offers both propagation and azimuthal resistivity measurements from a compact sub.

With a sub length of 8ft(~2.4m), the tool permits assembling of a complete M/LWD toolstring in shops.

The tool is designed to run with low-speed MWD systems with data telemetry rates on the order of 1 BPS.

The toolcan be run above either an RSS or a motor.

Atbit Resistivity GeoTracker

The GeoTracker tool delivers, for the first time, compensated propagation resistivity measurement at or near the bit.

With the patented side-mounted antennas, the tool provides 16 sectors of attenuation and phase-shift measurements from a rotating BHA.

The depths of investigation of the measurements range from a few inches to 30 inches.The tool may be run either below a motor, right above a rotary steerable system (RSS), or as part of an RSS.

When run below a motor, the measure point is as close as 12 inches from the bit.

EM short-hop is available for transmitting the data across the motor to the MWD system.

Like traditional propagation resistivity tools, the GeoTracker* tool works in almost all kinds of mud.

RMS Strata-Multi Frequency Propagation Wave Resistivity

Is a spatially compensated, dual frequency (2MHz & 400 kHz), dual spacing device designed for wireline equivalent logging while drilling (LWD) services in all types of wells.

Applications include: geosterring correlation, casing point selection, logging while tripping and reservoir evaluation.
