Abstract: Systems and methods for simulating subterranean regions having multi-scale, complex fracture geometries in a realistic simulation environment, which includes in the modeling process three-dimensional multi-scale rock discontinuities, hydraulic fractures, and heterogenous reservoir properties. Non-intrusive embedded discrete fracture modeling formulations are applied in conjunction with commercial or in-house simulators to efficiently and accurately model subsurface characteristics including three-dimensional geometries having combinations of complex hydraulic fractures and multi-scale rock discontinuities.

Abstract: Disclosed are a tandem modulation device fan and a control method thereof. The tandem modulation device fan comprises a frame, fan blades disposed in the frame, and a light-emitting module disposed in the frame. Two corresponding sides of the frame are each provided with a circuit board and a pin structure. Pins and the circuit boards on the two sides can automatically switch and recognize inputs and outputs irrespective of the polarity. The two sides, provided with the circuit boards, of the frame are each provided with a magnet for magnetic connection with the frame of an adjacent fan. The circuit board is electrically connected to a master controller. Fans are connected end-to-end through attraction of magnets, such that the electrical conductivity is improved, and the service life is prolonged.

Abstract: Techniques for calibration of a simulation of a subterranean region having complex fracture geometries. Calibration of indeterministic subsurface discrete fracture network models is performed via non-intrusive embedded discrete fracture modeling formulations applied in conjunction with well testing interpretation and numerical simulation. Subterranean fracture networks are characterized dynamically by embedded discrete fracture modeling to accurately and efficiently determine an optimal fracture model.
