Low Pressure System Performance and Economic Analysis as a Production Enhancement Initiative for Bayan Field

This project is aimed to determine the reliability of a new generation production
enhancement technique, which is Low Pressure System or LPS. It is currently
implemented in two fields in Malaysia. Bayan is one of the fields which is the main
concern in this project. Since LPS is a newcomer in oil and gas industry, it is not widely
applied yet to the depleting oil fields worldwide. The main concerns are to determine
how efficient is LPS in boosting oil production and reactivating idle wells at Bayan
field. Besides, there is a need to determine the economic viability of the system's
implementation at the field, as well as finding the most potential candidates to
maximize oil production from LPS. Thus, this project comes with three solid objectives.
First is to determine the performance efficiency of LPS at Bayan field. Next is to
determine its economic viability by conducting engineering economic analysis. The
third objective is to identity new potential wells to be connected to the system. The
scopes of this project revolve around calculating the percentage of increase in oil
production prior to and after being connected to LPS, as well as conducting a detailed
engineering economic analysis on the implementation of the system. Another scope
involves building well models using WellFlo™ 2010 to identify potential well
candidates for the system. A strategic methodology is used throughout this project. The
four major elements include data acquisition, LPS performance analysis, engineering
economic analysis and building well models. The outcome of this project has shown
that the system managed to increase production from the field by 209%, and
successfully reactivated idle wells. The system has also been proven as economically
viable with the calculated incremental Internal Rate of Return (IRR) being higher than
the Minimum Attractive Rate of Return (MARR). Lastly, two wells were identified as
potential candidates to flow through the system in order to maximize production from
the field.
