the change in pulsed neutron capture created by acidizing a carbonate. Acidizing increases interconnected porosity and strands chlorides and other ions in the rock.

use of a mineral acid (typically HCl or HCl/HF) or an organic acid (typically acetic or formic) to remove damage or stimulate the permeability of a formation.

n: an acid that has been chemically treated before the acidizing or acid fracture of a well to lessen its corrosive effect on the tubular goods and yet maintain its effectiveness. See acid fracture, acidize.

n: an acidizing treatment using low or no pressure to improve the permeability of a formation with fracturing it. See wellbore soak. Compare fracture acidizing.

acidizing a rock below the fracturing pressure, either to reduce the formation damage or to improve the initial permeability.

adj: descriptive of a substance whose strength or merit has been exhausted in a process. For example, after a well has been acidized, any acid that remains in the well is said to be a spent acid because its strength has been used up in the acidizing process.

n: any process undertaken to enlarge old channels or to create new ones in the producing formation of a well (e.g., acidizing or formation fracturing).

any effort to increase production from a well by the improvement of natural or damaged flowing capability.

n: an additive used to hold the fine clay and silt particles that sometimes remain after an acidizing treatment in suspension;i.e., it keeps them from settling out of the spent acid until it is circulated out.

a precipitate of sulfate minerals following acidizing with strong hydrochloric acid.

n: any of several operations used to increase the production of a well, such as acidizing or fracturing. See acidize, formation fracturing.
