i need general info about drilling mud ??

Question

its composition
its importance

Answer 1

standard drilling mud is made with barite, sometimes mixed with water, but in today's drilling environment, it more often gets mixed with a synthetic oil. Usually there are other additives, such as something to thicken the mix, or thin it, sometimes it's made heavier to control the well, depends on the situation. The more barite added to it, the heavier it gets, the more of a static head it produces, thereby enabling it to keep the pressures from the depths under control. What else ya wanna know?

Answer 2

Its a power.
85% of It comes from Wyoming
People in Casper call it Baby Poop.

Ship's out to and types of Drilling operation's

The five primary purposes of drilling mud or drilling fluids are to:

Remove cuttings from the formation produced by the bit at the bottom of the hole and carry them to the surface. This is achieved by adjusting the rheology of the mud system.
Lubricate and cool the drill bit during operation as friction causes high temperatures down-hole that can limit tool life and performance. This is particularly important if the bit is of the roller-cone type.
Maintain hydrostatic equilibrium so that fluids and gas from the formation do not enter the well bore causing the well to flow, kick or blow out. This is achieved by adjusting the mud weight (density). High-density additives (barite, hematite) are used for preparation of kill-weight fluids, which create hydrostatic pressure that prevents water entering the well or hold the oil/gas inside, prevent a blowout and to physically stabilize the formation. The exception to this role is when drilling an underbalanced well.
Build a filter cake on the hole wall, preventing fluid loss in mud invasion of penetrated formations.
Support and prevent caving of the wall of the hole.

Good Question

Answer 3

Drilling fluids (Muds) consist of two types: oil-based and water-based. These fluids are made up of a base fluid (water, diesel or mined synthetic compound), weighting agents and other materials that aid in removing cuttings from the well and keep the mud in a fluid state.

Traditionally, the drilling industry has used water-based muds (WBMs) because they are inexpensive and have minimal impact on the surrounding marine environment.

In difficult drilling situations, such as horizontal or extended drilling, deep wells, and reactive shales, drillers rely on oil-based muds (OBMs). However, despite their high-performance properties, OBMs are costly to dispose of and contain toxic materials, such as mineral oil.

ask a gay man they drill mud a lot.
