Almost all operators use percentage Non-Productive Time (NPT) as a measure of efficiency, concluding that a well drilled with a low % NPT represents a “better” performance than a well with a high % NPT. This, however, is not necessarily true. If two identical wells are drilled with 10 days NPT where the first well took 100 days in total resulting in 10% NPT and the second was drilled more aggressively in just 50 days, resulting in 20% NPT. The 20% NPT well represents the better drilling performance despite the higher % NPT figure proving that % NPT is meaningless standalone. This, however, only provides a useful measure if NPT is, in fact, capturing all the inefficiency in the drilling process. If it is only capturing some part of the total inefficiency, then the NPT metric is of limited use in measuring total performance.
Technical Limit (TL) is a challenging reference level that is the ‘time is the time it will take to drill a theoretical well assuming a flawless operation on the basis of current
knowledge and design technology for all involved systems’
(David Bond and Phil Scott). TL is derived by analysis of
historic well data and taking into account offset data and the
opportunities team members perceive exist based on their
Technology implementation requires time, resources

priorities to ensure the safest and fastest results
achieved in the early phases.
