the theoretical maximum flow that a well could deliver with a zero backpressure at the middle of the perforations.

n: (am) modulation of the amplitude of a radio carrier wave in accordance with the strength of the audio or other signal. amplitudes n pi: shapes and heights of the peaks in a spontaneous potential curve.

n: 1. one of two electrodes in an electrolytic cell;represented as the negative terminal of the cell, it is the area from which electrons flow. In a primary cell, it is the electrode that is wasted or eaten away. 2. in cathodic protection systems, an electrode to which a positive potential of electricity is applied, or a sacrificial anode, which protects a structure by forming one electrode of an electric cell.

the positively charged site in a cell. Oxidation site. The site of metal loss in corrosion.

polarization to a higher oxidizing potential to achieve a reduced corrosion rate (promotes passivity).

absolute open flow potential.

v: to overcome the positive electrical potentials of anodic areas in cathodic protection systems.

n: A kind of invert emulsion mud that the chemical potential of drilling fluid is equal to the chemical potential of water in the drilled formation. The salinit in the water phase is usually equal to salinit in the shale water. It can prevent shale permeatin

n: a highly painful and potentially fatal condition in which air or other breathable gases come out of solution in the bloodstream and cause distress or death. So named because the bending joints of the body are most often affected. Also called decompression sickness.

a test measuring the concentration or build-up of potential harmful chemicals in a living organism.

n: (C) the ratio of an impressed electrical charge on a conductor to the change in electrical potential;measured in farads. See capacitor.
