In this paper, the unknown parameters could be obtained based on a hierarchical approach strategy. The whole ,fracturing, process is discrete into time sections and the ,fracturing fluid, rheological parameters and total leak-off coefficient can be obtained dynamically. In this optimization model, time domain is discrete into time sections.

Andrey Smarovozov: There are several ways of minimizing ,fracturing fluid, formation damage factor, (as well as a proper stress proppant application is a must): 1. Low polymer loading systems (such as BJS’s QuadraFracТМ which allows us to decrease polymer loading down to 18-20 ppg from 30-35ppg system) with similar proppant carrying capacities.

This ,chart, depicts the evaluation of three diversion designs compared with a baseline design. Diversion designs 1 and 2 show minimal improvement in fracture half-length compared with the baseline design. Design 3 shows a significant improvement in diversion and cluster efficiency, as shown by a reduction in fracture half-length.

About 1/5 of the water used in hydraulic ,fracturing fluid, returns to the surface, and must be treated, at the expense of drilling companies, to remove toxic byproducts of fracking. Drilling companies operating in the Marcellus must also take the necessary steps to prevent harmful groundwater contamination , which occurs when drilling chemicals and byproducts leak into the surrounding area.
