Abstract
A method for producing fractures in a formation to release hydrocarbons (such as a hydrocarbon gas or liquid) from the formation is disclosed. The method comprises reducing the in-situ temperature at a location in a formation having a first temperature by contacting the location with a first fluid and contacting the location with a fracturing fluid to produce fractures in the formation while the location is at a second temperature below the first temperature to release hydrocarbons from the formation. The method can include using an endothermic process to reduce the temperature at the location in the formation.
