Oil drilling mud composition
Drilling mud, also known as drilling fluid, is a product which is used in the process of drilling deep boreholes. These holes may be drilled for oil and gas A fluid is required in the wellbore to: Cool and lubricate the drill bit,; Remove the rock fragments, or drill cuttings, from the drilling area and transport them to the Water-based drilling mud most commonly consists of bentonite clay (gel) with additives such as barium sulfate (barite), calcium carbonate (chalk) or hematite. Various thickeners are used to influence the viscosity of the fluid, e.g. xanthan gum, guar gum, glycol, carboxymethylcellulose, Composition of a typical oil based mud density 1318 kg/m3 , salinity 22.5%, oil to water ratio 65:35. components combine to give a total volume of one barrel.(bbl: barrel; ppb:pounds per barrel; gpb: gallons per barrel) Oil-based mud is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. The oil base can be diesel, kerosene, fuel oil, selected crude oil or mineral oil. Drilling mud is made up primarily of barite and bentonite clays. Usually its delivered in fine powder form in bags and mixed on site with either oil or water, water being the primary base. Some other chemical s may be added for various reasons. Oil-Based Mud Systems and Nonaqueous Fluids (NAF) Oil-base muds are composed of oil as the continuous phase, water as the dispersed phase, emulsifiers, wetting agents, and gellants. Other chemicals are used for oilbase mud treatment, such as degellants, filtrate reducers, and weighting agents.
Key Words: Drilling fluid, Water base mud, Oil base mud, Mud formation damage restrictions either on the composition or on the properties of the drilling fluids.

The basis of the improved drilling gj fluid is an oil, preferably crude oil or an oil such By treating the same composition with 4 cc. of concentrated sulfuric acid, An oil-based mud (OBM) uses a petroleum product (rather than water) effects of a particular mud system vary depending on the composition of the initial fluid.
Oil Based Mud is an oilfield emulsion which is used as a drilling fluid while performing drilling operations. In this type of oilfield emulsion, oil is present as a continuous phase (or in large amount) and water is present in the dispersed phase in low amounts of approximately 2% to 5%.
*The UK offshore industry is one in which large quantities of chemicals are used, both in the drilling and completion of wells, and in the production of oil and gas. One classification scheme, given here, is based only on the mud composition by singling out the component that clearly defines the function and performance of Key Words: Drilling fluid, Water base mud, Oil base mud, Mud formation damage restrictions either on the composition or on the properties of the drilling fluids.

2 Jun 2015 There are several different types of drilling fluids, based on both their composition World Oil's annual classification of fluid systems lists nine distinct the morphological and mineralogical composition of the reservoir rock. Wastewater from oil and gas well drilling operations is enriched with heavy metals, including barium and lead. Studies have been conducted to assess the impact I want to make Oil Based drilling mud in the lab for experimentation purpose. Composition: 10-20% bitumen; 1,5-3% of sodium soap of oxidized paraffin; 0,7-1 Oil-based muds were developed to prevent water from on wireline tool compatibility with drilling fluid composition, see *The UK offshore industry is one in which large quantities of chemicals are used, both in the drilling and completion of wells, and in the production of oil and gas.
