It is important for us to make sure that there is a higher rate of oil recovery. This has to be done at quite an affordable cost too. You will observe that for a while now, newer techniques are being used in this recovery process. This is basically due to the innovative technology that is in place. This advancement in technology has also led to the increased demand of both oil and gas. Therefore, these techniques purpose to get the best out of each reservoir. These advanced technologies are what have brought about the recovery of more than fifty percent of the oil that is formed. This recovery is put into three stages.
There is the primary recovery stage. This is the first stage that is entered once the well has been completed and is flowing. There is the involvement of an artificial lift in this process. You will note that most of the time it will involve the various types of electrical, mechanical as well as hydraulic lifts. You will also observe that most of the treating methods in the well’s production will be covered in this stage. It also goes ahead to consider stimulation of the production. This stage will basically rely on naturally occurring pressure that lies within the reservoir. It is known to recover about five to twenty percent of the oil.
After that we have the secondary recovery stage. It is often characterized by the use of water flood or even gas injection. This is aimed at ensuring that the pressure within the reservoir is safely maintained. Using this flood technique will always make sure that there is an injection of a fluid or gas in one well which then pushes the oil to the second well. This second well is where the fluid or gas is then recovered. One of the commonest methods used is the water flood. You will have to employ a lot of expertise in this process due to its demanding nature. In essence, it is the one that introduces external energy to this reservoir. This is the stage where about twenty to fifty percent of the oil is collected.
The tertiary stage is often characterized by the use of combined forces. Such could be the combination of both natural gas and carbon dioxide. The use of heat and water can also be employed. This is directed towards the production of enough steam. You will also learn that is the stage that slugging is commonly used. You will note that there is effectiveness and better yields under this stage. You will learn that it is necessary for improved oil recovery. It is quite pricy. However, this is the only way to make sure that we meet the growing demand of oil and gas.
