Abstract
The applicability to prototype wells of a suggested maximum design velocity of axial flow of 1 m s-1 for an efficient horizontal well, derived using a model experiment (Kim et al. 2008), was investigated. The Darcy-Weisbach equation associated with the Manning’s formula was analyzed using the Euler-Cauchy method and the frictional resistance was investigated in the case of both model and prototype laterals. Results showed that the frictional resistance to the axial flow was smaller in the prototype well than in the model well and that the design velocity obtained from the model experiment was also applicable to the prototype wells. However, the results should be applied with caution since the conclusions need to be verified employing a prototype well. It should also be noted that the methodology involves some sources of error since an uniform discharge intensity is assumed over the entire length of the wells. Moreover, the methodology adopted in this study employs a phenomenological rather than hydraulic approach (especially in Fig. 2). In spite of these limitations, the results of this study appear to be useful in practice, especially in the prediction of the production rate by both analytical and numerical methods and in the diameter design of horizontal wells.
