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.
A well kill operation places a column of special fluids of the required density into a well bore. This well control technique is done to prevent the flow of reservoir fluids without the need for pressure control equipment at the surface. It works on the principle that the hydrostatic head of the kill fluid or kill mud will be enough to suppress the pressure of the formation fluids.
Not all well kills are deliberate. On occasion, the unintended accumulation of fluids, either from injection of chemicals like methanol from the surface, or from liquids produced from the reservoir, can be enough to kill the well, particularly gas wells, which are notoriously easy to kill.
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.
Where P is the pressure at a specific depth, h, within the column, g is the acceleration of gravity and ρ is the density of the fluid. It is common in the oil industry to use weight density, which is the product of mass density and the acceleration of gravity. This reduces the equation to:
Where γ is the weight density. Weight density may also be described as the pressure gradient because it directly determines how much extra pressure will be added by increasing depth of the column of fluid.
The objective of a well kill operation is to make the pressure at the bottom of the kill fluid equal (or slightly higher) compared to the pressure of the reservoir fluids.
