The installation of equipment or application of techniques to prevent migration of reservoir sand into the wellbore or near-wellbore area. In weak formations, sand control may be necessary to maintain the structure of the reservoir around the wellbore. In other formation types, the migration of sand and fines into the near wellbore area may severely restrict production. Each of these conditions requires different treatments. The principal sand-control techniques include gravel packing and sand consolidation

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
