n pi: hydrocarbons that are gaseous in the reservoir but that will separate out in liquid form at the pressures and temperatures at which separators normally operate. Sometimes called distillate.

n: 1. a product of distillation, i.e., the liquid condensed from the vapor produced in a still. Sometimes called condensate. 2. heavy gasoline or light kerosenes used as fuels.

n: light fuel oils distilled during the refining process and used primarily for space heating, on- and offhighway diesel engine fuel, and electric power generation.

a range of manufactured products from the refining processes;includes kerosene, diesel, bunker C oil, fuel oil, heating oil, etc.

n: the process of driving off gas or vapor from liquids or solids, usually by heating, and condensing the vapor back to liquid to purify, fractionate, or form new products.

n: Process of first vaporizing a liquid and then condensing the vapor into a liquid (the distillate),leaving behind nonvolatile solid substances of a drilling fluid. The distillate is the water and/or oil content of a fluid.

n: a qualitative method for detecting hydrogen sulfide and mercaptans in petroleum distillates. The test distinguishes between sour and sweet products.

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: hydrocarbons in the middle range of refinery distillation, e.g., kerosene, light and heavy diesel oil, heating oil.

refinery products in the middle distillation range of refined products: kerosene, heating oil, jet fuel.
