Summary A computer program was developed for the simultaneous selection of a roller-cutter bit, bit bearing, weight on bit (WOB), and drillstring rotation that minimizes drilling cost per foot for a single bit run. Two drilling models were tested wit

Abstract In recent years the application of steerable bottomhole assembly (BHA) systems in drilling directional and horizontal wells is quite common. The quality of their performance and the amount of time spent in the hole often determines the succe

Abstract An algorithm, based on the steerability of a bottom hole assembly (BHA), has been developed which can predict the complete geometry of the most suitable BHA to drill a given section of a directional well. The model is particularly versatile

Abstract A joint effort was undertaken by an oil company, a research institute, and a service company to carry out field operations using foam cement. This was achieved by understanding the fundamentals and technology involved, as they stand today. T

Abstract PDC bit technology has developed into an attractive and economical alternative in many drilling scenarios. Although much has been done for bit selection and optimization for tricone bits, much is still to be done for PDC bits, due to the dif
