Abstract

The Objective of this project is to study the types of water injection pumping system and their performance, related to deepwater reservoirs and to analyze the pressure maintenance effectiveness using ECLPISEIOO reservoir simulator. Producing hydrocarbons from deepwater reservoirs is a challenge faced by most oil and gas companies to sustain for high and long production life. For effective pressure maintenance, a good pumping system design is critical due to very high pressures associated with deepwater reservoirs. A good design of the pumping system together with the injection wells location could provide good results for pressure maintenance and lead to higher production rates. The Scope of Study was to do a literature review of water injection facilities assessment, their performance and problems associated with their operations. Literature review of the types water injection pumps used and their trend in the future and finally a simulation work using ECLIPSE I 00. The methods used to achieve the objectives of this project are, a) Conducting literature review of work pertinent on water injection, b) Communicating with companies specialized in oil and gas pumping systems c) case study was conducted by doing the simulation work on Gelama Merah reservoir model using ECLIPSEIOO, Black oil simulator where water injection wells and production wells were designed on the model to run the simulation. This study concluded that, the main water injection types suitable for water injection are a) Multistaged Centrifugal pumps and b) Reciprocating Positive Displacement Pumps. Due to the trend of usage on the market, most of the Oil and gas companies tend to use Multistaged Centrifugal pumps, due to several advantages over the reciprocating pumps such as the cost of maintenance and space available on the platform for pumps for offshore operations. Using Line drive injection pattern for Water injection, suitable pressure maintenance can be achieved. The ratio between the water injected and oil produced for equals number of wells of producers and injectors is 2STB (IIP=2). Use of miscible gas injection to the reservoir could improve the pressure maintenance this is due to the high production of this gas as obtained in the field production.
