PRODUCTION ENHANCEMENT BY USING ELECTRICAL SUBMERSIBLE PUMP

This research project is to to design the suitable electrical submersible pump
(ESP) component to be used for high water cut well which is PP-7, Pelanduk Putih
Field, Offshore Sabah. ESP is one of artificial lift method that is used worldwide
today, which the whole assembly is submerged in the fluid to be pumped. Another
problems in PP-7 well are pressure depletion, sand production problem and side
pocket mandrel has mechanical problem and then was categorized as idle well. The
project problem is how to design the most ideal ESP systems, that can extend life of
the systems since the installation cost of ESP are very expensive. So, most of this
project were run in production software such as PROSPER, in order to find the most
efficiency and optimum ESP components.[9] By having different results from
different parameters, the author will compare and choose the ideal one that can fix in
solving the case study problem. Thoughout 2 semester period of this research project,
in first period, the author need to have the study on theory, engineering application
and installation procedures of the artificial lift application especially on ESP system
from papers, journals and books. Next, the author will determine the suitable ESP
components from the results and graphs. End of the project, the author found that the
pump, REDA DN1800 that has pump efficiency about 74.45%, number of stages is
107, motor efficiency about 84.40% and the motor speed is 3443.llrpm. From the
designing, the well can reproduce again about 1349 STB/Day with 60Hz power
supply.
