APS Technology, Inc. products

APS’s SureShot™ mud pulse family of directional and directional plus gamma systems provides reliable and flexible Measurement While Drilling (MWD) performance in combination with our second-generation Rotary Pulser – the toughest top-mounted pulser in the industry. This MWD system provides highly accurate azimuth and inclination data for all applications, from straight-hole through horizontal drilling. Rapid and accurate toolface transmission enables the most complex well paths to be drilled with confidence.

The APS SureShot™ EM telemetry MWD system communicates by transmitting electromagnetic waves through the formation instead of pressure pulses through a fluid column. Benefits include time saved by transmitting surveys during a connection, high data rates and the ability to operate in conditions where mud pulse telemetry cannot.

This MWD system provides highly accurate azimuth and inclination data for all applications from straight-hole through horizontal drilling. The DDS includes a tri-axial fluxgate magnetometer and three quartz accelerometers in APS’s unique ruggedized package. Simultaneous 16-bit analog-to-digital conversion of all channels assures the best possible directional measurement while rotating. APS Technology offers local NIST-traceable DDS recalibration in China, Russia, Dubai, and the United States, which simplifies R&M logistics and improves asset utilization.

APS’s next-generation SureShot™ MWD natural gamma sensor employs a rugged scintillation counter and photomultiplier mounted in a specially designed package which provides protection against the high levels of shock and vibration encountered in the drilling environment. In addition, this extensively qualified new design offers environmental monitoring capability and lower power consumption, while maintaining back-compatibility with APS’s earlier sensor designs.

APS`s WPR™ Wave Propagation Resistivity sub is a spatially compensated, dual-frequency (400 kHz and 2 MHz), dual spacing device designed for wireline-equivalent logging while drilling (LWD) and measurements after drilling (MAD) services in all well types.

Operating directly behind the drill bit, the iPZIG at-bit inclination and gamma ray tool provides real-time measurements that reduce directional drilling risk in critical hole sections. The early indication of changes in lithology, delivered by the gamma ray log, helps to accurately land horizontal wells. Designed to operate as two separate subs, a lower sub, located directly above the drill bit, acquires data and transmits data to the upper sub, located above the drilling mud motor. The upper sub provides communication to measurement/logging-while-drilling systems.
