Simple Engineering Applications Recycled as Effective Training Aids

Abstract

Summary Technical advances have led to both expansion and increased specialization in the engineering skills employed in our industry. In many cases, these specializations involve the use of complex engineering calculations involving a bewildering number of inputs and outputs to match real-world situations. Another problem with high-end applications is that they are costly and their logic is often presented as a "black box"—disclosure may be hampered by intellectual-property concerns. Although such high-fidelity applications may be essential for operations, simpler models with few inputs are better for scoping exercises or training. The rapid and effective transfer of knowledge and experience to new hires with diverse backgrounds remains a key challenge. Though information technology and richer media have helped standardize delivery methods, accessing appropriate engineering applications for training purposes remains a challenge. The important requirements are to communicate the fundamentals and build on knowledge gained at university. At the same time, the teaching methods and modules should instill curiosity and encourage critical assessment of the models and methods used. Therefore, the models should not be too far from reality. Technical progress and refinement of a broad range of topics are inherent in the content and structure of the SPE paper library. The application to training is illustrated using examples including the simple 2D bottomhole-assembly (BHA) algorithm presented by Walker (1973). This paper shows how key refinements have been included by use of simple geometrical constructs and how the model has been used effectively in spreadsheet form to develop an understanding of BHA behavior and directional-survey-sag correction, and to identify and correct programmatic errors. It is suggested that greater use can be made of the SPE library as a ready source of cost-effective training material and that the descriptions of the simpler engineering applications it contains can be recycled as valuable training aids.
