n: a reef or mound built by small organisms and their remains, such as coral, plankton, and oysters. Originally a waveresistant coral structure served as an anchor for calcareous debris that formed limestone. It was tectonically submerged, or the sea level rose faster than the corals could build it, and it was eventually buried beneath marine shales. A bioherm is often porous enough to hold large accumulations of hydrocarbons, especially if it has been dolomitized. A bioherm is a stratigraphic trap.

n: the hydrocarbon liquid lighter than kerosene that can be recovered by catalytic or thermal cracking in a refinery.

the sonic travel time in microseconds per foot, of a sound wave through the formation. Denser formations (generally better consolidated and cemented) have lower (faster) delta t times.

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

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.

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

n: a receptacle on the drawworks drum to which the drilling line is attached.

n: the rosette of the winch drum on which the steel wire is fixed

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: a part of a mixture of hydrocarbons, usually defined by boiling range--for example, naphtha. gas oil, or kerosene.
