Abstract
"Multi-stage hydraulic fracture completions in horizontal wells have facilitated economic development of natural gas from unconventional and tight gas reservoirs.Industry has relied on two horizontal multi-stage completion technologies: cemented and perforated liner or Plug-and-perf method and Openhole Sleeve Multi-stage method. Each method has its own advantages and disadvantages. However, one of the most important questions is which method yields better gas production? Computation fluid dynamics (CFD) is a powerful tool for solving complex fluid flow problems. In well completion design, CFD plays a significant role aiding the completion engineers on making decision on well completion methods. In this study, a three-dimensional CFD model of a horizontal well with a single transverse fracture has been constructed to compare Plug-and-perf versus Openhole sleeve multi-state completion methods using steady state natural gas production and no formation damage. The results are shown in a relationship of dimensionless fracture conductivity and fold of increase. Parametric studies have been performed varying horizontal permeability ratio, penetration ratio and propped fracture width. Considering only the effect from the completion method and without the presence of the natural fractures, results of this study indicate a well completed with Openhole Sleeve Multi-stage method does produce more than a well completed with the Plug-and-perf method, but the difference in production is substantially less than previous publications indicate. The results from this study were compared with the previous study using the two-dimensional models by Augustine (2011)"--Abstract, page iii.
