Abstract
Steam injection is a common EOR – Enhanced Oil Recovery – method that consists in injecting steam inside the formation in order to increase or allow production. During the flow of steam to the formation a lot of heat is lost to the environment through the injection equipment, and this may compromise the recovery efficiency in some cases. There are a few strategies able to reduce the heat loss during the flow, including the use of thermal insulation in the equipment that compose the injection column and the fluid transport pipeline. Usually, those insulated tubing and pipeline are more expensive than the common equipment, because of the difficulty of manufacture and boarded technology, and also are more difficult to install. These limitations must be evaluated comparing the expected cost and the simulated benefit in order to determine if the use of thermal insulation is economically viable in each project and what kind of insulation should be used in each case. This paper describes a computational method to run these thermo-economic simulations and demonstrates its applicability and reliability in some steam injection scenarios.
