The problem the invention solves
In horizontal oil wells, highly viscous crude oil is difficult to extract through conventional means due to its inability to flow into the production liner effectively. This increases extraction costs and reduces efficiency.
The core features of the invention
This invention introduces a technologically advanced bottom-hole heater for horizontal oil wells. It utilizes electrical resistance heating cables placed coaxially along a supportive rod within the production liner to reduce crude oil viscosity.
The inventive step
The novelty lies in using a PEEK-insulated electrical conductor that is highly resistive to extreme pressures and temperatures (up to 250ºC and 10,000 psi). The heating system employs trifasic power to evenly distribute heat, preventing overheating between conductors.
The tangible benefits
Enhances oil flow by uniformly reducing the viscosity of crude oil, leading to increased oil extraction rates and reduced energy use in pumping operations.
The broader impact
By improving oil extraction efficiency, this system potentially reduces the environmental footprint of oil wells and promotes safer, more sustainable drilling practices globally.
