A clay mineral that is composed principally of three-layer clays, such as montmorillonite, and widely used as a mud additive for viscosity and filtration control. Commercial bentonite ores vary widely in amount and quality of the swelling clay, sodium montmorillonite. Ores of lower quality, those with more calcium-type montmorillonite, are treated during grinding by adding one or more of the ...

Barite Plugs | Tertiary Control | Well Control

A barite plug is a slurry of barite in fresh water or diesel oil which is spotted in the hole to form a barite bridge that will seal the flow and allow control of the well to be re-established. The plug is displaced through the drillstring and, if conditions allow, the string is pulled up to a safe point above the plug.

Drilling mud | excavation | Britannica

Drilling muds are traditionally based on water, either fresh water, seawater, naturally occurring brines, or prepared brines. Many muds are oil-based, using direct products of petroleum refining such as diesel oil or mineral oil as the fluid matrix. In addition, various so-called synthetic-based muds are prepared using highly refined fluid compounds that are made to more-exacting property ...

Mineral Resource of the Month: Barite | EARTH Magazine

The mineral barite (barium sulfate), also known as barytes, is most commonly found in hydrothermal veins and as veins in limestone. It is very dense (it has a high specific gravity) and is relatively soft. Those properties make it an excellent weighting agent in drilling muds for petroleum wells. In fact, worldwide, oil and gas drilling account for 85 to 90 percent of barite consumption.

Barite sag is intensified at the low side, by the very low velocity present in that area of the well. Flow loop testing has proved that a sag mechanism can be set up at shear rates as high as 95 sec^-1. In reaching these conclusions many wells were analyzed and only one incidence was found where barite sag was reported while drilling.

Drilling Mud - an overview | ScienceDirect Topics

Drilling muds are divided into two general types: water-based drilling muds and oil-based drilling muds. Each type needs special additives which are discussed in this chapter. The type of fluid base used depends on drilling and formation needs, as well as the requirements for disposition of the fluid after it is no longer needed.
