Abstract
The potential of casing cost reduction is investigated by using an optimization technique. A simple recurrent computer procedure for the minimum-cost casing in vertical wells if derived. Application analysis reveals 24% casing cost reduction as well as several special applications. A new model of the minimum-cost casing design in directional wells is developed. Directional data are used for casing loads calculations, then the minimum-cost casing string is selected. An anlaysis of the effect of directional well geometry and the borehole drag on the minimum casing cost is performed. This paper and the optimization computer programs provide the casing designer with the complete cost-related information necessary to make the best decision.
