n: a well stimulation method using acid. See acidise.

n: a log used to determine the contribution of each zone to the total production or injection. These sureys are used to indicate chages in the flow pattern versus changes in conditions at the suface, in time, in type of operation, or after stimulation treatments;particularly useful for measuring gas well flow.

cyclic steam stimulation.

n: when explosives are used to fracture a formation. At the moment of detonation, the explosion furnishes a source of high-pressure gas to force fluid into the formation. The rubble prevents fracture healing, making the use of proppants unnecessary. Compare hydraulic fracturing.

one of several techniques used to break the rock in the near well area. It was an early stimulation method. Fractures formed in this method are short. Although still used, its best application is in perf breakdown and overcoming some near well damage.

n: shortened form of formation

a stimulation method involving injection of fluid into the well at a high enough pressure to break the rock. Fracturing “failure” of the rock is a tensile failure as the wellbore in enlarged by pressure.

high energy gas stimulation.

n: 1.A stimulation treatment routinely performed on oil and gas wells in low-permeability reservoirs. Specially engineered fluids are pumped at high pressure and rate into the reservoir interval to be treated, causing a vertical fracture to open. The wings o

n: an operation in which a specially blended liquid is pumped down a well and into a formation under pressure high enough to cause the formation to crack open, forming passages through which oil can flow into the wellbore. Sand grains, aluminum pellets, glass beads, or similar materials are carried in suspension into the fractures. When the pressure is released at the surface, the fractures partially close on the proppants, leaving channels for oil to flow through to the well. Compare explosive fracturing.

n: an acid compound, HCI, commonly used to acidize carbonate rocks. It is prepared by mixing hydrogen chloride gas in water. Also known as muriatic acid.

the most common oilfield stimulation acid. A mixture of hydrogen chloride gas in water. Useful for removing calcium scale, some mud and cement damage and very shallow stimulation of formations with some calcium in the flow path.

raising the pH of the backflowed acid to the neutral point.
