Claims (11)
1. Postupak za proizvodnju vodika iz rezervoara nafte (18), naznačen time što postupak sadrži:
a. osiguravanje bušotine (12, 34, 42, 52, 62) od površine do rezervoara (18);
b. lociranje u bušotini (12, 34, 42, 52, 62) najmanje jedne vodik-permeabilne membrane (76, 86, 96);
c. zagrijavanje rezervoara (18) kako bi se omogućilo da se javi najmanje jedna od reakcija rasplinjavanja, voda-plin promjene, i akvatermolize između naftnih ugljikovodika i vode unutar rezervoara (18) kako bi se generirao tok plina koji sadrži vodik; i
d. omogućavanje toku plina da uđe u bušotinu (12, 34, 42, 52, 62) i angažira najmanje jednu vodik-permeabilnu membranu (76, 86, 96), tako da najmanje jedna vodik-permeabilna membrana (76, 86, 96) dozvoljava prolaz samo vodiku u toku plina na površinu.
2. Postupak prema patentnom zahtjevu 1 naznačen time što korak zagrijavanja rezervoara (18) sadrži injektiranje oksidacijskog sredstva u rezervoar (18) kako bi se oksidirali barem neki naftni ugljikovodici unutar rezervoara.
3. Postupak prema patentnom zahtjevu 1 naznačen time što korak zagrijavanja rezervoara (18) sadrži generiranje elektromagnetnih ili radio-frekventnih valova pomoću elektromagnetne ili radio-frekventne antene (32, 44) postavljene unutar rezervoara (18).
