How to Increase Your Oil field Production

How to increase you oil field production
These steps are based on my experience and my thoughts that could increase your oil production from daily monitoring or well surveillance works,

1. We must know the productivity or IPR (inflow performance relationship) of all wells. Then try to model it the vertical lift performance and find out the operating rate the subjected well. If your operating point position on the IPR curve is at the left side of the IPR curve, then you have to think to increase this operating rate to move it at least to the middle of rate range on the IPR. This can be done by reducing the well head pressure or if it is already minimum or 100% opened you must consider other ways to create more drawdown in the bottom hole (installing bigger tubing size, ESP etc).


2. Review all the shut in wells in your field. And try to find the reason why it was shut in. Once you have known the problems, try to reactivate the well using new technology etc and also make the economical consideration and risk assement.


3. Check well performance if it is declining, try to find the answer why it is declining. If reservoir pressure issue, then we don’t have too many options to improve its performance. However, if you can find other reason likes skin or something that reducing the flow such as scale, sand problem or any solid doposit built up in welbore, we have to do something like pump clean up, wellbore clean up or matrix stimulation, sand controll installation etc. By knowing the problem it will make us easier to have better mitigation action plan.


4. Subsurface or GGRE review, need to review all the unopened pay zones behind casing of each wells either shut in or active wells. And also to consider secondary recovery technique to increase recovery factor or change out the artificial lift method with highr drawdown can be created than the exisisting one.


5. Create model of surface facility that is connected to the wells performance or it’s called well integrated production model to know and simulate the current operating system and find opportunities to do debottlenecking projects, Production optimization, etc.
   Hope those steps useful for you all.
