Integration of New Evaluation Tool for Production Forecast Management In PHM: A Success Story

Abstract

An integrated material balance tool (new software) was introduced and used to improve the reliability of field production forecast. The integration of this tool will be elaborated in three phases : 1) Selection Phase; describing the approaches to select the software including the calculation speed comparison of each available software in the market, 2) Integration Phase; describing the efforts to ensure that the software is fit for forecast purpose and ready to use as part of business process; and 3) Improvement Phase; elaborating how the software evolving become a dependable evaluation tool for future development projects and other purposes. The new tool tackles the major limitation of the previous tool where surface constraints were not integrated thus resulting in a more reliable production forecast.  Evaluating short term and long term forecast as well as future development projects is now faster. It is also bringing the benefit of efficiency, as the calculation speed of the software allow more detailed evaluation of project production forecast profiles at the same timeframe. All of these improvements eventually contribute to field development optimization. Some of the projects were benefitted from the software such as well head compressor (WHC) and drag reducer agent (DRA) which were dedicated to Sisi Nubi and South Mahakam fields. The evaluaton tool integration process is practical and relatively easy to replicate. This paper also demonstrates how the integration of surface limitation and subsurface evaluation brings additional value for field development.
