Gas anchor, английский
Used to prevent gas lock, this tubular and perforated device works by allowing the lighter gas to rise, while the fluids make their way to the pump. it works like this: fluids first enter the anchor, while gas rises and exits the anchor through the perforations at the top. the rest of the fluids enter the anchor through a mosquito bill which allows all the gas to escape before fluids enter the pump.
Over balanced drilling, английский
Used to describe instances where the pressure used to drill (from the drilling fluids) is more than the pressure of the oil or gas within the reservoir.
