This paper describes the current systems that are being developed and used in the petroleum production industry with processors and electronics that are currently available to the designer for production controls. It highlights the transition from mechanical to the initial attempt at electronics through the discreet systems of operation to the current designs that are providing a complete integrated overview of the well and its requirements to produce.
This paper discusses the ability of various operating and production philosophies to now be developed into actual working systems of specified formats and yet yield varied results due to those concepts that are applied. The truly innovative approach has now a means of becoming a reality in the processor based system. The overview of the current concepts is evaluated to show its current merit in today's need for efficient and truly effective stand-alone production systems.
The current trend of developing optimal production of wells at the best bottom line for equipment and work over is forcing many manufacturers of production equipment to reevaluate and redevelop their current lines of products to the present concepts of electronic adaptation to current systems.
This has led to certain old and less than reliable concepts being given a new insight due to microprocessor and processor controlled devices. The influx of electronic devices is not limited to any particular speciality in production operations but rather to the broad field of the equipment that falls under this title. This allows the user to evaluate the various production systems as they are currently used to produce the liquids from the well bore to the surface in a reliable and consistent cyclical routine.
The use of these systems does require the well to be placed upon an intermittent type of operation in all cases and this places the well into a cycle of production then recovery. The use of the intermittent cycle is relevant to our topic as it will be the one factor that all these systems share as a common requirement.
The use of this intermittent concept in production is not new and is a very successful step in the series of methods to be employed to produce the well. This is not a permanent or ultimate solution to enhancing or sustaining the well but its results are beneficial and will show marked increases in production of liquids and gas. This paper is an evaluation of those processor based controls that utilize this concept and obtained results are discussed.
The inability of a well to sustain continuous flow of gas and liquids to the surface and into the gathering system is a direct response of a combination of any or all of the following factors.
The first two types of reduced production can be so intertwined that they are often readily confused.
