Production Optimization for Natural Flow and ESP Well A Case Study on Well NS-5 Mishrif Formation-Nasriya Oil Field
As the reservoir conditions are in continuous changing during its life, well production rate
and its performance will change and it needs to re-model according to the current situations
and to keep the production rate as high as possible.
Well productivity is affected by changing in reservoir pressure, water cut, tubing size and
wellhead pressure. For electrical submersible pump (ESP), it will also affected by number
of stages and operating frequency.
In general, the production rate increases when reservoir pressure increases and/or water cut
decreases. Also the flow rate increase when tubing size increases and/or wellhead pressure
decreases. For ESP well, production rate increases when number of stages is increased
and/or pump frequency is increased.
In this study, a nodal analysis software was used to design one well with natural flow and
other with ESP. Reservoir, fluid and well information are taken from actual data of Mishrif
formation-Nasriya oil field/ NS-5 well. Well design steps and data required in the model
will be displayed and the optimization sensitivity keys will be applied on the model to
determine the effect of each individual parameter or when it combined with another one.
