Looking On The Bright Side of Oils

The Process of Recovery of Oil and Gas

It is important for us to make sure that there is a higher rate of oil recovery. 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 has been brought about by the current technology that is actually so advanced. 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. Modern technologies have led to the recovery of more than half of the oil that is formed. There are three basic stages that recovery takes place.

The primary recovery stage comes in first. 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. In most cases, it will include the various types of electrical, mechanical as well as the hydraulic lifts. You will also note that there are several treatment methods for the well’s production that are covered in this stage. It does go ahead to consider stimulation of the production too. 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 will usually feature the use of water flood or even gas injection. This is intended to make sure that the reservoirs pressure is properly maintained. The use of this flood technique intends to ensure that there is an injection of a fluid or gas in one well that will then make sure that the oil is pushed to a second well. It is in the second well that this gas or fluid is recovered. It is so common to find the water flood method being used. 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 stage accounts for the collection of between twenty and fifty percent of the oil.

The third stage will basically involve the use of more than two combined forces. This could be the use of both natural gas and carbon dioxide. Heat and water can also be used. This is directed towards the production of enough steam. Slugging is a common application in this particular stage. You will note that there is effectiveness and better yields under this stage. It is important to note that there is a global need to enhance oil recovery. It is expensive. However, there is no better way of meeting the growing demand of oil and gas.
