SureShot-MP

MWD Rotary Pulser – Mud Pulse Transmitter

Introducing the Next Generation in Pulser Technology

MWD Rotary Pulser - Mud Pulse Transmitter

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.

APS also offers an EM Telemetry-based MWD system, which uses the same flow subs and is a drop-in alternative for the mud pulse transmitter.

The mud pulse MWD system’s downhole portion includes a rugged directional sensor package with NIST-traceable magnetometer calibration; a reliable, field-proven Rotary Pulser*; and battery and/or turbine alternator for power. SureShot’s modular design allows for the addition of other functions such as high-quality gamma and/or vibration logging.

SureShot MP Pulsers
Built around the toughest, most advanced, most LCM-tolerantmud pulse transmitter in the industry.

Generation 4 Pulser

Single Pulse Motion

SureShot’s patented fourth-generation Rotary Pulser* is the toughest, most advanced, most LCM-tolerant mud pulse transmitter in the industry. Capable of 0.35 second pulse widths, the gen4 pulser delivers a faster single pulse motion and provides significant power savings over current rotary pulsers.

Mechanically, our gen4 pulser offers a new compensation seal location, adding a weep hole in the shaft on the bottom side of the valve, new 100:1 gearbox and superior cold weather performance. A ultra-reliable, high-efficiency DC brushless motor and controller, single open-flow path, positive pulse output and anti-jamming control virtually eliminates all jamming or blockage during the run.

Our G4 pulsers are currently deployed in the field with multiple installations for our US, Russian and Middle Eastern customers.

Features & Benefits

  • Built around the toughest, most advanced, most LCM-tolerant mud pulse transmitter in the industry.
  • Stores up to 32 MB of MWD/LWD and diagnostic data for retrieval during trips or for post-run processing.
  • Additional sensors including gamma, vibration monitoring and resistivity can be quickly enabled or incorporated into our “LWD-ready” system.
  • Data is presented in a simple, user-friendly control and display module; it is transferred to a central control PC, from which it can be directed back to a dedicated wireless rig-floor display and/or rig monitoring system.
  • Multiple encoding schemes and advanced decoding enable rapid customization of the data stream for maximum speed or maximum data integrity.
  • APS's unique power management module enables the system to be powered through dual battery packs or a combination of battery power and APS turbine alternator.

Design

  • Each package is protected by a state-of-the-art vibration isolation system and is mounted in ToughMet™ or high-strength steel pressure barrels.
  • A small, robust surface decoder interfaces with a computer running APS’s SureShot Control Center (SureShot-SSCC™) software.

The APS MWD system makes it easy to add higher-level MWD and LWD capabilities, including:

Adding these more advanced sensors is easy thanks to APS's new m-Con modular connector, which allows for quick, safe and reliable electrical and mechanical connections and provides maximum flexibility for placement within the BHA.
