Annotation:
The authors of the article consider the improvement of approaches to selecting the well bottom configuration for vertical and horizontal wells. The existing traditional methods are based on a rigid correlation between specific geological-lithological characteristics and production technologies. However, in practice, completely identical conditions of productive formations structure or operational methods are not encountered. It necessitates a transition from classical "rigid" models to adaptive decision-making systems capable of taking into account a significant spread of geological-lithological, filtration-capacitive and technological indicators.
As a solution, it is proposed to use facet coding of technical data, in particular, the classification of well bottom types. If previous studies considered the flexible selection method for vertical wells, the authors of the article describe its application to horizontal wells. The key advantages of the proposed algorithm compared to traditional schemes are: simplicity of software implementation and the possibility of adapting the system by oil and gas industry specialists by adjusting facet codes based on practical experience of operating various well bottom types.
