Title: Eimund Gilje: Innovator in Hydrocarbon Recovery
Introduction
Eimund Gilje is a notable inventor based in Oltedal, Norway, recognized for his contributions to hydrocarbon recovery processes. With a total of four patents to his name, Gilje has made significant advancements in the field of petroleum engineering.
Latest Patents
One of his latest patents is the "Solvent Injection Recovery Process." This innovative process focuses on the recovery of hydrocarbons from a hydrocarbon-bearing formation, utilizing an upper injection well and a lower production well. The method involves preheating the region between the wells by circulating hot solvent until hydraulic communication is achieved. Solvent is injected into the upper well at or above its critical temperature, with pentane or a mixture of butane and pentane being used. A hot solvent chamber is created, consisting of both solvent vapor and liquid, allowing for effective mixing of bitumen and solvent. The hydrocarbon and solvent mixture is then drained downwards by gravity and sideways by pressure gradient towards the lower production well, where it is produced to the surface.
Another significant patent is the "Solvent and Gas Injection Recovery Process." This method also targets the recovery of hydrocarbons, such as bitumen, from a hydrocarbon-bearing formation. It involves injecting a non-condensable gas into the solvent chamber created by the hydrocarbon solvent, enhancing the recovery process.
