... the intersection of the NF-HF planes. These elements have ability to model the fluid continuity at HF-NF intersection. It was observed that for high stress contrast the NF activated length is smaller compared with the low stress contrast. For high stress contrast with principal horizontal stresses reversed...

... work presents a method which automatically generates a 3D classified model from 3D point cloud data. An industrial point cloud is treated as a collection of pipes, planes and general objects, and we thus divide the modeling problem into three sub-problems: pipe modeling, plane classification...

A step-by-step procedure for analyzing pressure tests is included in this paper and illustrated by several numerical examples. hydraulic fracturing inclination angle flow line flow regime upstream oil & gas hhfd 0 plane pressure transient analysis penetration...

... fractures only, but multiple fractures are beneficial to reservoir stimulation in very tight reservoirs when the drawdown is limited to a narrow zone around the fractures. Multiple fractures are also needed when the reservoir has natural fractures aligned with the preferred fracture plane. In that case...

..., this representation implies failure occurring along a simple plane identified by its angle with the principal stresses. With the exception of simple purely tensile fractures, all underground formation failures occur along multiple planes. This is quite different than a laboratory experiment where the limited sample...
