Hot Crude Gravity Drainage (HCGD)
It consists of injecting hot crude oil through the annulus at high speed so that the liquid column drags all the sediments and asphaltenes that clog the liner.

The HCGD technology or continuous hot crude injection, consists of heating and continuously reinjecting a volume of crude produced from the intervened well, in order to increase the temperature of the oil and decrease its viscosity to increase the production rate. Temperatures and pressures in the reinjection process are variable, determined by the specific characteristics of each well.
Twenty to 25% of the crude oil produced by the well is used to heat it to 446 ºF and reinject it into the producing sand through the annulus between the production line and the producing liner with the aid of a thermal packer that partially isolates the producing zone.
A well producing 11" API crude oil, with five steam cycles, which initially produced 20 BPD, reached production of 250 BPD with the injection of 80 BPD. Profit: 180 BPD.
