There is always an urgent need to make sure that you recover as much oil as possible. This needs to be done with a relatively affordable budget. You will observe that for a while now, newer techniques are being used in this recovery process. This is due to the advancement in technology. This advancement in technology has also led to the increased demand of both oil and gas. It is these new techniques that then intend to get the best out of a particular reservoir. These advanced technologies are what have brought about the recovery of more than fifty percent of the oil that is formed. There are three basic stages that recovery takes place.
There is the primary recovery stage. Once the well has been completed and started to flow, it will automatically enter the first stage of recovery. It often involves the basic method of an artificial lift. This will often include 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 assumed to recover about five to twenty percent of the produced oil and gas.
Then follows 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. The use of flood technique will make sure that there is injection of a fluid or gas at one well in order to push the oil to the second well. It is in the second well that this gas or fluid is recovered. One of the commonest methods used is the water flood. This process is usually complex and needs extreme expertise. In a way it is responsible for introducing external energy to the reservoir. This stage accounts for the collection of between twenty and fifty percent of the oil.
The tertiary stage is often characterized by the use of combined forces. This could be the use of both natural gas and carbon dioxide. Heat and water can also be used. This is meant to produce enough steam. Slugging is a common application in this particular stage. This stage has more improved effectiveness and results. You need to note that there is a necessity for improved oil recovery. It is expensive. However, this is the only way to make sure that we meet the growing demand of oil and gas.
