Prior to the DMX512 protocol, analog control systems were used; zero to ten volt analog was one common standard. 912 0 obj <>stream converges towards a fit between Data Driven and Model Driven approach. DMX512 is a standard for digital communication networks that are commonly used to control stage lighting and effects. Adequate treatment of spatial organization is perhaps the most problematic gap in many DFN models. against pre-existing joints. A novel network growth model to construct larger scale fracture systems is developed. length data and geomechanical models need to model the range of fracture sizes in 3D, simulate interfaces, and account for cement. topology) and allow for the representation of a complex arrangement of fracture networks. Laser scanning is a very efficient way to generate realistic, high-resolution digital models of 3-D geological outcrops. between fractures and geological structures. in the subsurface and challenging to obtain from outcrops. Some specific aspects of geological fracture and faults patterns need to be taken into account: introduce the concept of "Discontinuity" which includes them both. and image log information) to the observed fracture and fault pattern. to be boosted with a DMX-Booster.

As a result the sensitivity analysis showed that key parameters affecting fracture intensity are fracture orientation (Trend / Plunge). The need for better laboratory testing methods for fractured rock samples, conceptual models of broader applicability, and numerical modeling systems capable of more complex reservoir descriptions and conditions remains. © 2008-2021 ResearchGate GmbH. This paper utilizes these four factors to obtain, 3D fracture network model is built based on discrete fracture surfaces, which are simulated based on fracture length, dip, aperture, height and so on. or less accurately describe the spatial variation of these characteristics.
