a diesel fuel, C10-C14+ typically. #1 Diesel has paraffins removed for cleaner operation or cold weather use.

n: a light hydrocarbon mixture for diesel engines, similar to furnace fuel oil;it has a boiling range just above that of kerosene.

n: an internal-combustion engine used to power a drilling rig. From two to six engines are used on a rotary rig and are usually fueled by diesel fuel, although liquefied petroleum gas, natural gas, and, very rarely, gasoline can also be used.

n: the internal combustion engine used as drilling rig power

n: a method of stimulating production by opening new flow channels in the rock surrounding a production well. Often called a frac job. Under extremely high hydraulic pressure, a fluid (such as distillate, diesel fuel, crude oil, dilute hydrochloric acid. water, or kerosene) is pumped downward through production tubing or drill pipe and forced out below a packer or between two packers. The pressure causes cracks to open in the formation, and die fluid penetrates the formation through the cracks. Sand grains, aluminum pellets, walnut shells. or similar materials (propping agents) are carried in suspension by die fluid into the cracks. When die pressure is released at the surface, the fracturing fluid returns to the well. The cracks partially close on the pellets. leaving channels for oil to flow around them to the well. See explosive fracturing, hydraulic fracturing.

n: a way that increase the production of crude oil by increase layer permeability.

n: a fluid used in the fracturing process (i.e., a method of stimulating production by opening new flow channels in the rock surrounding a production well). Under extremely high hydraulic pressure, frac fluids (such as distillate, diesel fuel, crude oil, dilute hydrochloric acid, water, or kerosene) are pumped downward through production tubing or drill pipe and forced out below a packer or between two packers. The pressure causes cracks to open in the formation, and the fluid penetrates the formation through the cracks. Sand grains, aluminum pellets, walnut shells, or similar materials (propping agents) are carried in suspension by the fluid into the cracks. When the pressure is released at the surface, the fracturing fluid returns to the well but leaves behind the propping agents to hold open the formation cracks.

the fluid used in a fracturing treatment, may include pre and post treatment fluids.

n: 1. diesel fuel.2. heavier liquid hydrocarbons. such as bunker oil, that is used to fuel turbines on a ship or other vessel

one of many refined petroleum oils such as heating oil, diesel, etc.

n: see gas injection. gas oil n: a refined fraction of crude oil somewhat heavier than kerosene and often used a.., diesel fuel.

n: in a drilling rigs fuel-supply system, a large tank in which diesel fuel is stored. If the rig has a day tank, it is filled from the main tank;otherwise, the main tank supplies fuel to the engine. Compare day tank.

n: a simple or complex liquid mixture of hydrocarbons that can be refined to yield gasoline, kerosene, diesel fuel, and various other products.

n: a fuel oil similar to diesel fuel that a turbine compressor bums. Some turbines do not require fuel as high in quality as a reciprocating engine, such as a diesel engine.
