Drilling: Efficiency and Aggressiveness in Performance Drilling – Effects On Drilling Mechanics, Drilling System Analysis
The terms efficiency and aggressiveness, play key roles in Performance drilling, with regards to project planning and execution. They influence drilling system (bit & reamer/BHA/drive system, hydraulics, drilling parameters etc.) design for different applications. The system then impacts how projects are executed, which then determines how success is measured in actual field situations.
Presently, there are several different positions on what the two terms are, and what they represent. Consequently, their perceived influences on the performance drilling process also generate lots of debate. Whereas certain groups assume the two terms to be the same, others argue for an inverse relationship. This situation has arisen, primarily due to the lack of practical field driven definitions for the terms – from a drilling dynamics standpoint. As a result, their actual effects on product development, drilling system analysis, and performance drilling, still remain inconsistent.
This discussion will define efficiency and aggressiveness, from a practical field driven perspective, with supportive data. The effects of the two terms on product development, drilling system analysis, and performance drilling will also be discussed. Most important, their effects on bit/reamer development and matching, BHA design, and drilling system analysis in “hole opening applications”, particularly in harsh environments will be discussed.
