What is Hot Oil? Heavy crude oil (or extra heavy crude oil) is highly-viscous oil that cannot easily flow to production wells under normal reservoir conditions. It is referred to as “heavy” because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. Physical properties […]

What is horizontal drilling? Horizontal drilling can be referred to as the directional drilling of an oil well in a horizontal direction rather than vertical. Since most oil wells are drilled in a vertical direction, horizontal drilling helps in stimulating the well in a different way to extract most of the produce from the reservoir. […]

Gas or gasoline is a natural gas liquid that has vapor pressure somewhere between the condensate and LNG (Liquefied petroleum gas). It is a light weight volatile mixture of hydrocarbons, which only contains carbon and hydrogen atoms. Commercial gas (gasoline), which has been refined for use is normally used in vehicles that have internal combustion […]

Formation fluid refers to the naturally occurring liquids and gases contained in geologic formations.[1] Fluids introduced during the drilling process are called drilling fluids. Fluids in an oil or gas reservoir are called reservoir fluids. The fluids flowing from the wellhead of an oil or gas well are called production fluids. Formation Fluid is the […]

Fluid Coupling is a mechanism which helps in transferring the rotational force from one axis to another axis. The axis can be termed as transmitted and receiving axis. The transfer is done with the help of an accelerated or decelerated fluid (oil). The acceleration of load to the maximum and the starting of the motor […]

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostlynitrogen (typically more than two-thirds) derived from […]

Ferrous Sulfide, A corrosion by-product [FeS2] formed when hydrogen sulfide [H2S] contacts the iron [Fe] present in steel. Ferrous sulfide is a black crystalline material at bottomhole conditions. However, when it contacts air at surface, it will be converted into iron oxide, which is a red-brown compound. Ferrous sulfide is also called iron sulfide. Ferrous sulfide […]
What is a ferrous alloy
A Ferrous Alloy is an alloy that has iron as its prime constituent and a small amount of carbon in it. It can also contain steel as its component. It plays an important role in industrial applications as it is widely used in manufacturing tools. Drill bits, which are cutting tools, are made by using […]
Enhanced Oil Recovery
Enhanced oil recovery (abbreviated EOR) is the implementation of various techniques for increasing the amount of crude oil that can be extracted from an oil field. Enhanced oil recovery is also called tertiary recovery (as opposed to primary and secondary recovery). According to the US Department of Energy, there are three primary techniques for EOR: […]
What is Core Drilling
A core drilling is a hollow, cylindrical drill used to make holes through a surface. It is made of metal, and its drilling tips are coated with diamond or carbide. The tool is composed of a motor, a handle or base, and drill bits. The hollow center of the drill is used to carve out […]
