Abstract: Drilling operations are validated whether the objectives of the wells are achieved within a time frame that is faster than the planned drilling time without compromising safety. The drilling costs in general are going to be reduced only if the drilling time is less than the planned program. While developing a field considerable numbers of similar wells are required to be drilled for big oil/gas fields. The performance of the drilling contractor is best compared to one another by means of time follow-up and non-productive time (NPT) monitoring. The purpose of this study is to give the methodology in which the acquired codes throughout the daily drilling reports are handled in a specific manner and the category for the NPT occurrences of various contractors are compared to one another in a proper quality control practice in place. The novelty of the proposed methodology in this study is the possibility to monitor the drilling performance history of the contractors. [Received: November 11, 2015; Accepted: October 19, 2017]
