3.2.4 Hydraulic Fracture Summary and Recommendations
Results presented here are the average of two transverse, conductive and producing fractures per stage
in either the DFN or Planar modeling scenario. Although the created DFN lengths are shorter than the
Planar model, the sum of propped dominate primary fractures created by the Discrete Fracture Network
is similar to the propped single fracture created in the Planar models solution. Fracture width and fluid
efficiency in the DFN model is less those solutions in the planar model because the same fluid volume is
being used to create complex fracturing geometry. Comparison of Posidonia and Aalburg fracture
geometries can be found in the
Table 3-8, Comparison Results for DFN and Planar Fracture Geometry (20/40-mesh RC proppant),
Posidonia Shale and Table 3-9, Comparison Results for DFN and Planar Fracture Geometry (20/40-mesh
RC proppant), Aalburg Shale below.
