Steam Injection System
The steam injection system plays a role in heavy oil projects, where injected steam is used to stimulate a reservoir’s production. The modeling of a steam injection system contemplates water and gas requirements, and the associated costs and capacity constraints.
PetroVR uses specific Units for steam volume and steam rate, where a liquid unit label is characterized by a prefix CWE = "Cold Water Equivalent". Thus, 1 CWE bpd expresses the amount of steam equivalent to 1 bpd of cold water.
The actors involved in the generation and injection of steam are:
Steam Plant: Generates steam from incoming water. 
Steam Injection Facility: Routes steam to steam injectors. 
Steam Injection Well: Injects steam coming from an injection facility.
In Thermal projects, a pane Steam Injection Options is shown in the reservoir Injection Tab, with options similar to those of water and gas injection.
Steam injection system runtime variables
The following Runtime Variables refer specifically to steam injection activities.
