The public is aware the salt can only be acquired through underground mining. Nonetheless, its actual process is not revealed to most consumers. In general, customers are not aware that pricing salt is cheaper because of its simple production. Although it seems that the product is inexpensive, the actual processes and materials used for mining salt is no joke. The process is called salt cavern engineering, which will be discussed all throughout this article.
Salt and Its Features
The importance of salt comes from its innate features making it ideal for storage of gases. The strength of salt is high with plastic flow to nearby fractures in some extent. It has permeability and porosity to both gas and liquid products, which closes in stored gas. Moreover, salt caverns are plausible for high deliverability because pores do not release pressure. Instead, its permits cycling through injection and production in just minutes.
Salt Cavern Engineering
Most salt formations are found in large domal structures or in bedded salts. The depths range from 600 to 7000 feet. Salt caverns are built through well drilling into any salt structure. This will then leach out and produce strings hung into caverns from the last casing string. Caverns are normally elongated and typically thousands of feet in height and hundreds of feet in diameter. The stability of caverns following operation starts with geometrical sonar checks and seismic monitoring techniques.
Responsibilities in Salt Cavern Engineering
Developing a salt cavern includes integration of different disciplines, which are the following:
- Planning, design, and execution of debrining and leaching programs for salt caverns become a collaborative effort concerning subsurface engineers and rock mechanic engineers.
- Drilling engineers are responsible for the well program and also plans the drilling methods for optimizing the construction phase.
- Reservoir engineer performs simulations and studies for identifying suitable reservoirs in brine disposal.
- Geologists work on evaluating the geophysical and geological data to prepare the geological site characterization. It is their duty to produce data on salt, cap rock, and strata characteristics that surround the salt structure.
In each cavern, the engineers demolish the future road desiccant. Most of the trucks are designed specifically in hauling the salt communicates for large piles of road salt to a place that is already separated. Oftentimes, the road salt will be locally used for other safety transit purposes. Nonetheless, countries having no inclement weather may export the salt through the ocean to the developed countries having constant demand for industrial salt.
