Casing an Integral Part in Oil Drilling Assignment

Casing an Integral Part in Oil Drilling - Assignment sampleConductor casing does vary in diameters from 18 to 30 (Mid Continent, 2014).Freshwater zones are isolated from the well of oil by surface casting. This makes sure that the waters remain uncontaminated in the acting and completion process. Such environmental issues have compelled some countries to put in place regulations governing cement graphic symbol as well as casting depth. A surface casting classic size is 18 5/8 inches.Intermediate casting helps slander the hazards, which underground formations could pose to the well. It also prevents blowouts by supporting maintenance of hydrostatic pressure at the appropriate levels. Intermediate casing happens to the coherentest casting atom found in a well.Liner strings at times can be used as an alternative to intermediate casting. They are slight permanent compared to an intermediate casing and are used often for cost reduction (Mid Continent, 2014). The liner is hung righ t from the base of the prior casting interval and non from the surface, as a replacement for being cemented in place.Production casting is the final and it happens to be the deepest section of well casing. It does provide a channel for oil color producing formation to the surface. Its size does depend on several considerations. For instance for a well expecting future deepening, production casing should wide enough for a drill bit to pass through.Well, a casing is done in sections (joints) of around 40 feet long and joined together in order to form long lengths known as casting strings (Rigzone, 2014). Every end of a casting joint does have male threads, which are under the protection of a thread protector, till the casings become ready for joining. A coupling or collar made of a cylindrical pipe that is short but bimestrial slightly in diameter than the joints and has female threads connects the male joint ends (U.S. Department of Labor, 2014).
