Abstract Shale gas reservoirs generally need to be fractured massively to reach the industrial production, however, the ,flowback, ratio of fractured shale gas wells is low. In view of this issue, the effects of natural fracture spacing, fracture conductivity, ,fracturing, scale, pressure coefficient and shut-in time on the ,flowback, ratio were examined by means of numerical simulation and ...

The initiation and propagation of hydraulic fractures will cause stress redistribution and may activate natural fractures in the reservoir. Due to the limitation of the analytical method in calculation of induced stresses, we propose a numerical method, which incorporates the interaction of hydraulic fractures and the wellbore, and analyzes the stress distribution in the reservoir under ...

This work describes the development of a solid-phase extraction method capable of detecting common ,fracturing fluid, additives in ,flowback, and produced water with mass spectrometry. Dissolved organic carbon (DOC) was used as a bulk measurement to investigate the retentive capacity of seven sorbents and to determine a loading volume.

1. Introduction
1. Introduction

Multistage hydraulic ,fracturing, is a key technique for the effective exploitation of tight reservoirs. In the process of multistage hydraulic ,fracturing,, a large amount of ,fracturing fluid, is injected into the formation. However, field data show that the ,flowback, rate of the ,fracturing fluid, after ,fracturing, is generally no higher than 30% [1].
