Barge

​​​​GEDCO owns two Barges for offshore drilling in both shallow and deep water. Both are custom built per Mr. Rigby's design. The big Barge is a Jack-up Barge so it can be lifted out of the water and create a stable work-platform in rough water lakes. It can operate in water as shallow as one foot or as deep as needed. It is self contained and has a built-in mud pit which is mounted under the deck. All drilling fluids are contained in the mud pit. All cuttings and drilling fluids are collected in 55-gallon drums and removed from the barge upon completion of drilling. It also has three containment systems for possible spills.

Additionally, the barges are equipped with lighting for drilling at night.


A support boat is used to transport field personnel and samples to/from barge. This boat is equipped with a rest room, grill and refrigerator which allows the field crew to stay on board during breaks to maximize the daily production.

ATV RIGS/TRACK RIG

  • CME 55 HD ATV
  • ​CME 550 ATV
  • ​CME 850 TRACK RIG

GEDCO owns two types of ATV rigs; one is used for drilling on soft surface, where other rigs cannot access. The other type has shorter tires and is used for drilling on slopes, rough terrain and muddy job sites. Both perform flight augur, hollow stem, air/wet rotary and rock coring with capabilities of Army Corps of Engineers sampling standards.
