A horizontal well 1,000 ft long ( Lw) is drilled in a box-shaped drainage volume 4,000 ft long ( aH ), 2,000 ft wide ( bH ), and 100 ft thick ( h ). The well is off-center in the y -direction (parallel to the well), so dy = 250 ft and Dy = 750 ft. The well is also off-center in the x -direction so that dx = 1,000 ft and Dx = 3,000 ft.

History of Horizontal Wells

Early Horizontal Water Wells. Around the same time, water supply applications also began to explore the benefits of "going sideways". Leo Ranney (who came from the oil patch) began using radial collector wells for groundwater extraction in the mid 1930s. The first Raney water collector well in the United States was installed in 1936.

This can even lead to early closure of production wells, which can seriously affect the economic benefits. When researchers explore water control of horizontal wells, they usually use the method of plugging the water-producing section. ... Compared to vertical wells, horizontal wells provide the advantages of a larger contact area with the ...

Well types

Thin reservoirs. A conventional well will intersect a relatively thin section of the reservoir, whereas a horizontal well can run the length of the reservoir and produce much more hydrocarbons. [9] Horizontal wells can target long, narrow macroforms such as channel fill sandstones. Fractured reservoirs.
