MWD SYSTEMS

MWD SYSTEMS

Falcon MP MWD: It is a full-featured mud pulse MWD system, providing a telemetry foundation upon which all other SDI MWD, gyroMWD, LWD and rotary steerable components build.  Fully compensated and LCM tolerant pulsers deliver up to 5 BPS speeds in a variety of sizes to address your BHA configuration needs.

Target Applications

  • Bi-directional mud pulse telemetry
  • Positive pulse (1-5 bits per second)
  • Full accelerometer and basic dynamics package
  • SDI proprietary surface equipment and software
  • BHA sizes from 3.125” to 9.5”
  • Flow rates from 50 to 1500 gpm
  • Pressure ratings to 30,000 psi

Falcon EM MWD: It uses bi-directional communications and offer the advantage of very high data rates that are approximately four times faster than conventional MP MWD. Tools can be run in collar sizes from 3.125″ to 9.5″ OD and are available in a retrievable configuration when required.

Target Applications

  • Bi-directional EM telemetry
  • Multiple Pulse Patterns (3-16 bits per second)
  • Full accelerometer and dynamics package
  • SDI proprietary surface equipment and software
  • BHA sizes from 3.125” to 9.5”
  • Flow rates from 50 to 1500 gpm in all air, fluid and mist applications
  • Pressure ratings to 30,000 psi

GYROMWD

GYROMWD

The system consists of field-proven gyro and magnetic survey sensor modules combined in a single MWD tool. In most cases, the gyro sensor is used until the well clears external magnetic interference sources, at which time the gyro can be put to sleep and the magnetic probe can be used to complete the hole section without a trip.

The technology produces a tool capable of significant time savings over typical wireline conveyed gyros and conventional MWD tools. Additionally, gyroMWD eliminates the need to use wireline to acquire directional data while drilling, removing unnecessary hazards and personnel from the rig.

In addition to the obvious multi-well platform, top-hole scenario, recent projects have involved the system being used for whipstock setting/window milling operations where the tool is capable of remaining in-hole for the milling operation.

Our gyroMWD can be connected to Scientific Drilling’s Falcon MP and Falcon EM systems.

AZIMUTHAL GAMMA RAY SOLUTIONS

AZIMUTHAL GAMMA RAY SOLUTIONS

The azimuthal gamma ray solution provides measurements 20-25ft (6-8m) closer to the bit than the MWD. It is an excellent tool for Geosteering – helping to keep the bit within the “sweet spot” of the reservoir.


DELIVERING THE ULTIMATE VALUE

  • Provides azimuthal gamma and inclination measurements closer than standard MWD
  • Supports all BHA sizes
  • Works seamlessly real-time with both MP and EM MWD

MESUREMENT SPECIFICATIONS

  • Detactor Type - NaI Scintillation Crystal
  • Inclination Accuracy - Inclination: ± 0.15° all angles
  • Gamma Range - 0 - 1,000 AAPI
  • Azimuthal Gamma Bins - 2
