Abstract
This is a comparison study done on the heavy oil reservoir fields to estimate the production by the use of thermal recovery technique called In-situ combustion, in which the air is injected along with water and combusting it to increase the mobility of the heavy oils, thus enhancing the production in heavy oil fields. It gives an insight of the contrast between the theoretical estimations and the actual production of hydrocarbons on the field scale and helps in better and efficient optimization of the production from the field. An analysis was done by comparing the two methods namely Gates and Ramey method and Nelson and McNeil method and correlation was shown in terms of total oil produced and air/oil ratio based on the data of the field.
