Abstract:
Excessive water production is one of the major problems in Sudanese oil fields.
The main purpose of this project is to diagnose the excessive water production mechanisms as case of a Sudanese oil field.
The diagnostic plots derivative method is applied using Microsoft Excel format on calculating and plotting the derivative response to understand the mechanisms that create the problem, considering seven examples of a Sudanese oil well's data. As a result of this research, channeling is the main reason for water production in five wells, and normal with high water cut is the other phenomenon for wells.
