For any given drilling operation, several drilling technologies are available to optimize the process of producing a usable bore hole. The intent of this process is to conduct the drilling safely and in the most cost-effective manner possible. Our industry has made significant progress in developing improved technologies such as real-time formation evaluation, directional control while drilling, improved Bottom Hole Assembly (BHA) components and drilling fluids. These and other new technologies have added the requirement for specialized staff at the wellsite and at the same time have often reduced the role of the Driller. The challenge facing the industry for the foreseeable future is to find a more efficient method of utilizing these technologies while simultaneously reducing the need for certain specialized staff.
This paper analyzes the Driller's role and emphasizes his role as the critical link in safely and efficiently drilling a bore hole. As the industry moves toward the more cost-effective technologies of computer-based instrumentation, power handling tools and automated drilling, the Driller's role will need to evolve from one of basic drilling mechanics into that of a real-time drilling supervisor. In this way, the Driller (the only 100-percent real-time link with the drilling process) should become an active member of the wellsite management team, thereby reducing some need for specialized advisory staff.
In an age of the information highway where cost-effective computer networks are linking thousands of offices weekly, we find a problem unique to our industry:
Why must the man who is responsible for the real-time operation of a multimillion dollar oil rig and who is drilling a well in a multibillion dollar reservoir have to request his bit depth by telephone?
And if that well came in, why would he have to be told about ft by a consultant on the other side of the rig?
This paper explores these questions and identifies some of the drilling industry's major problems in re-engineering the rig site from a different perspective-that of the Driller.
From its inception, the Driller's role (in some cases) has been diluted to a point where the Driller now finds himself non-empowered. As wellsite technologies have moved away from the drillfloor, a dependence culture has emerged, isolating the Driller from interaction with drilling data and stalling the development of automated and closed-loop systems.
In order to better understand the current status quo, this paper explores the evolution of wellsite responsibilities. Using this historical perspective as a backdrop, it explains some of the resulting hurdles of today's wellsite technology optimization efforts.
