1. New onshore Wells: The oil industry often USES drilling and horizontal Wells at the bottom of vertical Wells, which can reduce several Wells, due to differences in geographic structure and oil and rock formations, or to reduce the number of Wells and surface pollution. Not only do you save on drilling costs, but you also save on casing, cropland - "you need a screen."

2. Offshore oil drilling: Due to the rise of offshore oil production in China and around the world, as well as the booming development of geothermal Wells, salt Wells and deep-water Wells, there is a need for screening.

3. Sand control of pumping pipe: When there is no screen in the casing, screen pipe can also be used for limited sand control -- "screen pipe is required".

4. Regeneration of old oil Wells: At present, a considerable number of oil Wells in the world's major oil fields have entered the late stage of oil production, and the oil production is decreasing year by year. To tap the potential of old Wells, the oil industry is grappling with a drastic reduction in annual oil production. They have exchanges, yes, that extend their underground catchings by drilling sideways "horizontal Wells" - "screens" - whether or not the owners are changed.
