Title: Jostein Alvestad: Innovator in Hydrocarbon Recovery
Introduction
Jostein Alvestad is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of hydrocarbon recovery, holding a total of 3 patents. His innovative approaches have the potential to enhance the efficiency of hydrocarbon extraction processes.
Latest Patents
Alvestad's latest patents include a "Solvent Injection Recovery Process" and a "Solvent and Gas Injection Recovery Process." The first patent presents a method for recovering hydrocarbons from a hydrocarbon-bearing formation using an upper injection well and a lower production well. This process involves preheating the region between the wells by circulating hot solvent until hydraulic communication is achieved. The solvent, which can be pentane or a mixture of butane and pentane, is injected into the upper well at or above its critical temperature. This creates a hot solvent chamber where bitumen and solvent mix, allowing the hydrocarbon and solvent to drain downwards and sideways towards the lower production well.
The second patent outlines a method for recovering hydrocarbons such as bitumen from a hydrocarbon-bearing formation. This method includes injecting a non-condensable gas into the solvent chamber created by the hydrocarbon solvent, further enhancing the recovery process.
