INJECTION STRATEGY TO DETERMINE HIGHEST OIL RECOVERY

The main objective of this project is to analyze different type of injection
strategies by comparing the reservoir performance after applying different type of
injection pattern and injection fluid techniques. The main parameter that crucially
observed in this project is the percentage of oil recovery after applying recovery
method, field reservoir pressure depletion, watercut and gas oil ratio from particular
field.Injection is important for secondary oil recovery and highly affecting the
performance of particular reservoir. In order to get the best or most efficient injection,
there are several factors that need to be considered such as injection patterns and also
injection fluid techniques. During FYPI, the author has implemented different type of
injection pattern through out several cases in the conceptual model where injection at
one corner of the reservoir from the bottom has proved the most effective pattern to be
applied in the model. However, the author cannot continue the project to the real field
like Angsi field that the author planned to do since the reservoir is homogenous and the
injection pattern do not effect much in the production of oil from the field. So, for FYP2
the author focused mainly on the different types of injection fluid techniques including
water injection, gas injection and also water alternating gas injection as the next
injection strategy to be implemented in the particular real field in Malaysia which is
Angsi field. The main methadology to be used in this project is simulation of Angsi
field by using Eclipse 100 as the main software and Petrel as the add-on software.
