Techniques for Drilling Optimization

Introduction:

Despite being a critical process in the offshore industry, drilling is sometimes taken for granted due to its time-consuming nature. Non-productive drilling time, however, is even worse as it represents the most significant form of time wastage. With the ability to optimize drilling performance, these issues can be improved. Drilling demystifies the need for a short-sighted approach in identifying optimization measures, using KPIs for gap analysis, data management, subsurface uncertainty acquisition, risk mitigation, assessment, and planning of drilling technologies and trends.

The rise in oil prices was disrupted by the development of fracking and enhanced oil recovery. Due to the challenges faced by several large oil producers, it became imperative for engineers to improve the drilling process to reduce non-productive time and cut production costs.

In today's world, without focusing on time parameters chronicling drilling operations such as comparison, analysis, and adjustments, success is unlikely. The application of these technologies is critical for engineers in optimizing oil well drilling.
