Abstract – Early water injection for X Field offers an opportunity for high initial oil rates due to lower gas production in a gas-constrained system. This study covers “Produced Water Supply” and “Produced Water Injection”: the chemistry study of fluid characteristics, scaling prediction, souring, corrosion, solid prediction, chemical inhibitor selection included chemical consumption prediction and material selection. Basically, the possibility to have the water supply in X Field is conducted following the scenario of two sources:

1. Aquifer or produced water in X Field or nearest water supply and

2. Y Field produced water (after separation from Bulk Separator). After reviewing the possibility of scaling precipitation, water compatibility, souring and continuity of supply and risk of deliverability the best economic decision resulted to take the water from Y Field and to control the quality of produced water and to avoid process problems, consumption of oilfield type of chemicals will require around 0,092 USD/barrel oil production.
