Optimal Configurations of Multiple-Lateral Horizontal Wells Conference Paper uri icon

abstract

  • Drilling multiple-lateral wells and employing intelligent completion systems would very likely lead to considerably higher productivity and increased recovery at relatively low incremental costs. Completing such a well system is a challenge and today it is still considered an extravagant effort. An important reason is that the performance of wells with multiple-lateral completions has not yet been investigated fully. There are several potential configurations for multiple-lateral wells, including planar, multi-planar, branches etc. The reservoir geometry and especially the areal and vertical-to-horizontal permeability anisotropies are critical. Using a versatile simulation model, the calculation of the multiple-lateral well performance is presented. Based on example calculations, optimum spacing, length and number of side-tracks are identified for various reservoir conditions. Shape factors for a number of well configurations are presented.
