[pdf] In geotechnical engineering, drilling fluid, also known as drilling mud, is used to aid the drilling of boreholes into the earth. Used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. The two main categories of drilling fluids are water-based muds (WBs), which can be dispersed and non-dispersed, and no. CompositionLiquid fluids are composed of natural and synthetic material in a mixed state, which can be of two types: • ; usually with substances added that control viscosity, along with lubricants, corrosion in. .
The functions of a drilling mud can be summarized as follows: Drilling fluid carries the rock excavated by the drill bit up to the surface. Its ability to do so depends on cutting size, shape, and density, an.
[pdf] This article lists the main components of a petroleum onshore drilling rig. Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but. .
