摘要： It is proposed a method of delivering chemicals such as scale inhibitor into a wellbore producing fluids including providing the chemicals, in a slow-released form, through a container located in the path of the production fluids so that the production fluids pass through the container. Preferably, the container is suspended to the production tubing and periodically retrieved out of the well to be refilled.
