Definition - What does Natural Fracture mean?
A Natural Fracture is a crack that occurs naturally on the surface of a rock formation without any movement. The crack is induced as a part of reservoir stimulation and drilling operations. According to a study, it takes about 33 to 35 million years to form Natural Fractures that are driven by the slow production of natural gas. It provides significant pathways for the flow of water, oil, and gas in geologic formations.
Petropedia explains Natural Fracture
The process of forming a fracture by pore-fluid pressure is known as Natural Fracturing. Due to advancement in technologies, the occurrence of fractures can be predicted beforehand. The knowledge of these fractures helps to optimize the performance of wells and reservoirs. The fractures act as medium for gas coning and water break through. Natural Fractures provide an opportunity to minimize drilling costs and do not have a negative impact on the environmental footprint. There are different types of Natural Fractures such as joint, fault, deformation band and compaction band. Natural Fractures also play a ubiquitous role in shale gas production.
