The study of overall well quality is a neglected area of the industry. Aspects such as formation damage, drilling interactions, and hole rugosity tend to be treated separately in the literature.

This paper describes a software tool that uses stored well data and drilling experiences to produce an overall set of well quality metrics that facilitate the assessment of drilling and completion performance in a given field. The tool is particularly useful for risk assessment when drilling complex trajectories and for improving the design of new deepwater wells.
