Gun barrel tanks are an economical low maintenance oil separator. Production enters into the flume. Through retention, the oil and water separate and the oil is drawn off the top and the water is drained off the bottom.

Belco offers several types:

  • Single chamber
  • Dual chamber
  • Custom built
  • Retention example: Customer has 1,000 BBL. per day; divide it by 4, giving you 6 hours of retention in a 24- hour period requiring a 250BBL gunbarrel. Retention time can change depending on the consistency of crude.

It used to be that the industry had to separate a little water from a lot of oil. Now it is important to get all of the oil from the water before it is injected back into the ground. Belco, with our 30 years of fiberglass experience, has built numerous Saltwater Disposals in Texas, New Mexico, Oklahoma, Louisiana, Colorado, Ohio, North Dakota, Arkansas, and expanding to several other locations.

  • Disposals can be made up of standard API design or custom built tank systems to meet the customer’s needs.
  • Belco can help build your disposal from the ground up, providing you with engineered drawings as well as necessary provisions to get your disposal up and running.

Belco maintains a new fleet of trucks and custom built trailers.

  • Trailers designed to ship multiple tanks per load, lowering your cost.
  • Lowboy trailers allow shipment of tanks up to 20-foot diameter with up to 54-foot of load space.
  • Crane trucks are available to allow for delivery and setting of most tank sizes.
  • Belco can ship coast to coast and has extensive experience with over-sized loads.
