Manufacturers of Oilfield Reliable Electric Bottom-Hole Heating System.

Heat helps the flow of any low gravity or waxy crude by eliminating solids and reducing viscosity. This improves flow in the formation, lowers lifting loads and costs and increase its daily production and total recovery. In many instances, electric bottom hole heaters have been the most successful method in generating and maintaining consistent, substantial improvements in well performance. In the past, these benefits have been reduced or even wiped out by the consequences of systems unreliability.

The David Industries Electric Bottom Hole Heater is a completely engineered system, fully field tested and to establish its proven reliability. The system supplies production zone heating in the most efficient and economical way now technically possible.
