SEQUENTIAL TRIPS OF HIGH WATER CUT WELLS

Baronia Production Platform (BNP - A) shutdown on high level of surge vessel was due
to one of the crude oil transferpump (COTP)trips. The response time for personnel from
Baronia Quarters Complex(crew BNQ- B) especially during bad weather condition is a
constraint. Currently BNP- A is running all the pump to sustain a high production of
crude; the problem is to maintain the surge vessel level if one of the pump trips. This
project is about integrating the instruments that will automate the sequential trips process
to prevent a total shutdown of BNP-A by tripping the wells that have high percentage of
water. The system is made use of the water cut sensors to determine the percentage of
water inside the particular wells and a level transmitter to sense the process level inside
the surge vessel. The newsystem wasdesigned at the lowest possible costs but withhigh
reliability. In designing the most applicable and reliable process level control system, the
Programmable Logic Controller (PLC) wasprogrammed to automate the sequential trips
process.
