Technology Implementation

Technology application is a fundamental aspect of business improvement of well engineers. Along with other improvement initiatives like Push the

Boundary and NPT reduction, the

implementation of technology can

and should be planned for in the yearly

business planning.

Any business plan should contain

aspiration and set of promises to

shareholders.

On the asset level that usually means a

yearly commitment to unlock a certain portfolio of reserves and produce a certain amount of oil and gas within a year.

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

experience.

Technology implementation requires time, resources

and patience. Technology implementation should be

priorities to ensure the safest and fastest results

achieved in the early phases.
