On Wednesday (19), the Legislative Assembly of Mato Grosso (ALMT) approved a draft law Shale gas exploration is prohibitedalso known as shale gas, is used by hydraulic fracturing in the state.
According to the project, the technique It has environmental risks associated with it, such as potential earthquakes, groundwater contamination, and large amounts of water wastage.
The purpose of the law is Protect natural water reserves and protect agriculture, which is the main economic source of the state of Mato GrossoSince this The technology means high water consumptionwhich may ultimately harm agricultural businesses.
Hey g1 He spoke with geologist Kayobi Kun, who said that research has already been done to implement this technology in the state, however, this exploration method is not currently used in Mato Grosso.
What is shale gas?
Shale gas is a term that has become popular in Brazil to refer to unconventional gas – extracted from shale rocks.
These resources are extracted from rocks with low permeability and low porosity. Both the gas and oil found in this type of rock formation are called “unconventional” resources.
The difference between “unconventional” and “conventional” exploration is the ease of extracting these resources.
Hydraulic fracturing or hydraulic fracturing
Hydraulic fracturing is a way to stimulate a well to increase productivity. The method consists of crushing rocks to open “spaces” through which gas and oil can flow.
Hydraulic fracturing is done by injecting fluids called “cocktails” – which contain water, fine sand and chemical compounds.
