摘要： A method for calibrating fracture networks. The method includes estimating an average fracture width of a fracture network using one or more of net fracturing pressure, Poisson's ratio, shear modulus, and fracture height; determining microseismic event envelope and base intensity data using a three-dimensional geomodel including microseismic event data; and determining hydraulic fracturing treatment (HFT) fracture intensity of post-hydraulic fracturing treatment (post-HFT) based on the average fracture width and HFT volume data. The method further includes calibrating the base intensity data to the HFT fracture intensity to obtain calibrated HFT fracture intensity, determining a proppant transportation and distribution scenario, and generating a dual porosity reservoir model based on the calibrated HFT fracture intensity and the proppant transportation and distribution scenario.

摘要： An integrated circuit that includes a processor also has an on-chip current test circuit that indirectly measures quiescent current in the processor. A supply voltage pin of the integrated circuit receives a supply voltage from an external test unit to provide power to the processor. The on-chip test circuit measures a voltage change across the processor during a predetermined test period T when the processor is isolated from the supply voltage and the clock signal is stopped. The voltage change provides an indication of quiescent current corresponding to the processor.
