How to predict Liquid Rate and Water Cut versus time
How to predict Liquid Rate and Water Cut versus time
(OP)
Is there any publised method to predict liquid production
and water cut progression with time ?
Anyone, please help
Thanks and Regards

RE: How to predict Liquid Rate and Water Cut versus time
Once you have the log WOR vs cum oil relationship, you can use decline curve analysis to forecast future rates. Assuming an economic limit WOR allows you to predict a cumulative oil produced to that economic limit. Of course, all of this is easier said than done. This is a quick and dirty approach, but is common for petroleum engineers to use as a tool. You really need to understand the reservoir and try to understand the source of the water. Is the reservoir relatively homogenous or is it fractured or have high permeability streaks? Is the water influx from the bottom or the edge? Is the water due to a coning of water? Of course the best approach is to build a reservoir model and try to match historic production and pressures to get a handle on what might be expected.
