Drilling legato - Essay ExampleThe bore fluid clogs the pores trim the rocks permeability. This results into validation damage that reduces or prevents production from the reservoir rock after the completion of the well.Lost circulation is other issue that is caused due to creation of highly porous and permeable formation in the underwater. The drilling fluid gets into the formation without forming up a filter cake. The lost circulation problem is solved by pumping down the muscular materials such as ground pecan hulls, mica flakes, sugar cane hulls or even chopped cellophane material into the well. They get into the pore spaces of the lost-circulation formation and swell up there closing off the formation and solving the problem.Blowout is caused due to unexpected pressure in the subsurface and fluid comes out of the subsurface rocks known as Kick. With the water or oil flowing into the well gets mixed up with the drilling mud and makes it lighter exerting less pressure on t he bottom. The blowout preventers are used to close the peck and to stop the Kick. The drilling mud is constantly monitored for its weight, electrical resistivity, or temperature to know if fluid is being solidus by subsurface
