Summary:A method of determining the position of a valve includes, measuring pressure at a first location within a bore and measuring pressure at a second location within the bore wherein the first location and the second location are positioned on opposing longitudinal sides of the valve. The method further includes analyzing values from the measuring and attributing characteristics of the analyzing to specific valve positions. Procédé de détermination de la position d'une soupape, consistant à mesurer la pression en un premier endroit à l'intérieur d'un forage et à mesurer la pression en un second endroit à l'intérieur du forage, le premier endroit et le second endroit étant placés sur des côtés longitudinalement opposés de la soupape. Le procédé comprend en outre l'analyse des valeurs provenant des mesures et l'attribution de caractéristiques de l'analyse à des positions spécifiques de soupape.
