Aps Technology

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.

SureShot EM is compatible with all APS downhole sensors. The electromagnetic transmitter uses the same flow subs and is a drop-in alternative for the mud pulse transmitter, having many parts in common with the SureShot mud pulse MWD system. Operators benefit from reduced inventory cost and increased flexibility when providing a mix of EM and mud pulse MWD services.

SureShot EM is a state-of-the art system with a downhole tool featuring two-way electromagnetic communication. The sequence and frequency of transmitted measurements is EM downlink selectable. Whether it's a higher density log to pick a casing point, more pressure measurements for drilling optimization or emphasis on directional measurements while sliding, SureShot EM enables the operator to quickly choose the optimum data sequence for the drilling operation.

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.

The APS MWD system uses either battery pack(s) housed in APS battery module(s) or a turbine alternator, which can be run alone or in combination with battery module(s). The APS Turbine Alternator is a high-temperature, axial flow design for use in measurement-while-drilling (MWD) and logging-while-drilling (LWD) systems. This device provides reliable, ongoing power at temperatures of up to 175°C, taking the place of expensive, short-lived disposable batteries. The turbine is configurable to match the required flow rates for typical BHA/hole size combinations.

AAPS’s MWD Pressure While Drilling (PWD) sensor measures annular and drill pipe pressures in all collar sizes. Captured data may be transmitted in real time via APS’s SureShot™ MWD/LWD system, or stored in downhole memory for later download and analysis. Real-time data or pressure alarms may be transmitted via SureShot.

APS’s SureShot™ MWD Vibration Memory Module (VMM™) is a software-enabled extension to our SureShot MWD tool that measures, analyzes, records and enables real-time transmission of axial (bit bounce), lateral and torsional (stick-slip, chatter and whirl) vibrations and shocks. VMM allows users to assess the severity of downhole drilling to improve drilling efficiency and alert them to vibration conditions that could damage MWD and other downhole tools.

The base model of our expandable SureShot surface system is the Sensor Interface Unit 2 (SIU 2.5), which includes everything needed to measure, filter, decode, display, store, retrieve, transmit and remotely access data for basic survey jobs. A separate PC and rig floor display can be added when needed for full directional MWD capability, and a depth tracking system (DTS) SIU 2.5 retrofit and Printrex plotter can be added for LWD service, when required.

SureShot’s intuitive, menu-based operating system allows you to lock-out some parameter changes while allowing the field engineer to still make necessary adjustments on the job. SureShot systems are available in both “ruggedized” and “lite” versions.
