In conventional drilling fluids, barite is used to increase the density. Though other additives such as halite (salt) or calcium carbonate can also be used. Mud weight can be decreased by dilution or solids control equipment such as an industrial centrifuge, desilter, desander and shale shaker . Mud weight use to control the trapped fluids or gas in the formations by adding a hydro static pressure on them . increasing the mud weight = increasing the hydro static pressure. if the hydro static pressure increased over the formations pressure that will make a frack in the formation leading to loss the mud to the formation , so adding loss circulation material like gel-flake or wood chips that can refill the gap and stop the mud loss . if the mud loss Continue then the hydro static pressure will decrees and that flammable fluids and gas trapped under pressure will start leaking to the surface and cause a blow out. So the mud or drilling fluids is super important factor in well control issues . ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mud weight」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
