Abstract
Fracturing fluid in a fluid tank is heated at a wellsite to protect against freezing of the fluid because of cold weather conditions. Convection currents induced in the fluid during heating cause fluid circulation in the tank to stir the fluid without additional equipment for that purpose.
Claims20
A well fracturing fluid tank for operation in low temperature conditions, comprising:
- a fracturing fluid container tank receiving a supply of fracturing fluid for application to a subterranean formation accessible by the well to fracture the formation;
- a fracturing fluid heater located in the a fracturing fluid container tank for maintaining the fracturing fluid above freezing temperature in low temperature weather conditions;
- and
- a mounting attachment for mounting the fracturing fluid heater with the fracturing fluid container tank.
1 more element
