Samples of rock that are broken down in the drilling process and rise to the surface with the drilling mud

An influx of formation water, usually salty and sometimes hard, into the mud in the wellbore. Saltwater flows contaminate freshwater or seawater muds, making it expensive, difficult and time-consuming to regain the mud properties.
Related to the processes associated with the presence of significance thickness of rock salt within a sequence of rocks. This is due to the fact that salt is mechanically weak and flows like a fluid. Salt is also relatively incompressible. Because salt is weak, its tectonism is closely tied to regional deformation
Type of survey to help define a salt sediment near a wellbore. This technique takes advantage of the fact that sound travels faster through the salt than the surrounding soft sediments and enables to receive a profile of the salt relative to the borehole
Intertidal wetlands that occur on the margins of estuaries, protected bays, and the landward side of barrier islands
The phenomenon of salt intrusion into rock caused by the difference in buoyancy and pressure between the salt and overlying rock
Salt cavern leaching is the process of drilling a well into a salt formation and cycling large amounts of water through the well to dissolve some of the salt and thus create a cavern for the storage of natural gas. Salt cavern leaching is used to create caverns in both salt dome and salt bed
