Title: Casing Cost Optimization For Complex Loading Situations
Author: Roque J.L.

Abstract: We present the optimization procedure, method and algorithm to minimize cost of a combination casing string. The algorithm is general and can be used with any commercial program, provided a few modifications are made for it to be used as a subroutine. To demonstrate its use, a commercial package (that can handle complex load calculations) is tested and the results confirm the effectiveness of the optimization procedure. Two complete examples are presented, that include cost predictions, for multiple combination casing strings using an extensive database of price and casing properties for the 9 5/8 inches (with 27 different casing types), and the 7 inches casing (with 64 different types). With such a great casing database to select from it would be very hard to obtain the cheapest string by trial and error.
