Study of Hydraulic Fracturing Real-time Evaluation Technology

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.

Fracturing fluid, absorption is in the range of 0.06 to 4.75%. The highest values were recorded for marls samples; in some cases ,fracturing fluid, absorption capacity was even higher than water absorption. This phenomenon indicates that the used ,fluid, is not suitable for ,fracturing, clay–carbonate rocks (marls).
