GSA Critical Issue: Hydraulic Fracturing
GSA Critical Issue: Hydraulic Fracturing

Hydraulic ,fracturing, is a technological process used in the development of natural gas and oil resources. Used commercially since the 1940s, it has only relatively recently been used to extract gas and oil from shales and other tight reservoirs economically. Development of lower cost, more effective ,fracturing, fluids (1), with horizontal wells

Fracking ,fluid, is then pumped at high pressure to create micro-fractures in the rock to release the gas. The fracking ,fluid, is a combination of: water; proppant (sand) which is used to keep the fractures in the shale open; and friction reducer, polyacrylamide, which is non-toxic and non-hazardous and approved for use by the Environment Agency.

The damage of fracturing fluid system mainly form two aspects : (1). Because dregs block up pore exist, seriously affect the fracture conductivity. Such as the dregs content of conventional guar gum fracturing liquid between 200~400 mg/L, the mean particle diameter is 74.77p,m, will block up cracks of reservoir natural and fracture. (2). Gelout liquid can’t flowback, form permanent damage.
