n: liquid added to dilute or dtin a solution.

the fluid added to a concentrated mixture to reduce the concentration of an internal phase or reduce its viscosity.

n: A kind of pozzolan cement whose cement/water ratio is higher than nomal
cement slurry used in well cementation.

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. the part of a breathing medium, such as helium, that serves as a transport for oxygen and is DOl used by the body as a life-support agent. Its purpose is to dilute the flow of oxygen to the lungs, thereby preventing oxygen toxicity. 2. in chemistry, gases that have a fined outer electron shell and thus do DOl easily react with other substances. Examples are helium, argon, neon, and xenon.

n: a storage battery in which the electrodes are grids of lead oxides that change in composition during charging and discharging, and the electrolyte is dilute sulphuric acid.

n: Water added to a maintain or dilute a water-mud system. The added water may be fresh water, seawater or salt water, as appropriate for the mud. Make-up water volume is an important parameter in a material balance check on solids content and solids removal

n: a primary cell in which the electrolyte is a dilute acid.
