Groundwater Water located beneath the earth's surface in pore spaces and in the fractures of rock formations. Can be potable or non-potable.
Horizontal drilling Drilling a well that deviates from the vertical and travels horizontally through a producing layer.
Hydraulic fracturing A controlled operation that pumps a fluid and a propping agent through the wellbore to the target formation at a high pressure in multiple intervals, or stages. A safe and proven way to develop natural gas, hydraulic fracturing has been used throughout the oil and natural gas industry for about 60 years. The fracturing fluids are designed to ensure effective fracturing of the target reservoir and recovery of fluids. The process breaks up the target formation, much like a stone fracturing a windshield, to create pathways that allow the gas to flow from the very low permeability reservoir toward the wellbore.
Hydrocarbons Compounds made up of only carbon and hydrogen. Fossil fuels are made up of hydrocarbons.
