Lesson plan
Well kill
A well kill is a well control operation of placing a column of special fluids of the required density into a well bore to prevent the flow of reservoir fluids without the need for pressure control equipment at the surface. The density of the column's fluids are intended to suppress the pressure of the formation fluids. The principle of a well kill revolves around the influence of the weight of a fluid column and hence the pressure exerted at the wellbore's bottom. Well kills may be planned in the case of advanced interventions such as workovers, or be contingency operations. The situation calling for a well kill will dictate the method taken. In order to reverse the well kill, the kill fluid must be displaced from the well bore.
