The MWD SHUTTLE was designed to meet the needs of the small-hole, horizontal drilling segment of the oil industry. Efficiently designed, the small diameter SHUTTLE produces positive pulses and offers low resistance to flow. Reliability and ease of operation are enhanced with a downhole assembly that is battery operated (extended operating times are possible with a second automatically switched battery pack). The SHUTTLE is designed and capable of meeting demands in directional and horizontal drilling. Additional cost efficient, competitive advantages of the MWD SHUTTLE include:
  • Simple design has no dedicated collar requirements - easily inserted into normal nonmagnetic drill collar.
  • Portability - easily transported by helicopter, van or pickup truck.
  • Unique flexible design, 50 degrees - 100 ft. natural flexure.
  • Capable of slim-hole use.
  • Horizontal, straight, and directional hole capability.
  • Shock mounted construction.
  • Capable of downhole operation in environments to +150 Centigrade and 20,000 psi pressure.
  • Capability for use with 9" down to 3-1/2" tools.
  • Directional and gamma measurement capability.
