George King is a technology provider in the oil and gas industry specializing in new technology and problem oil well solutions.
Usually differential sticking (by overbalance), but may also include effect of friction and mud cake adhesion to the tubing or drill string.
Industry:Oil & gas
Usually methane which is adsorbed and absorbed to the high surface area of the coal.
Industry:Oil & gas
Usually offshore; a platform from which wells can be drilled. It may be permanent (with legs grouted into the seafloor to depths of several hundred feet), anchored or dynamically positioned.
Industry:Oil & gas
Usually oil base or an oil external mud which will not conduct electrical charge. Many logs cannot be run in these muds.
Industry:Oil & gas
Usually slickline or CT logs that record data electronically and are downloaded later.
Industry:Oil & gas
Usually the vertical velocity gradient, i.e., the rate of change of velocity of sound traveling through rock with depth. Normally, it refers to seismic velocity at seismic frequencies, i.e., smoothly varying (rather than rapidly varying, as with a sonic log). With respect to material being sheared, velocity gradient is the change (dv) in relative velocity (v) between parallel planes with respect to the change (dz) in perpendicular distance (z) throughout the depth of the material. Velocity gradient has the same dimensions as rate of shear, which is reciprocal seconds.
Industry:Oil & gas
Usually used as a measure of additive, slurry or cleanout. Actually it is pounds of proppant in a gallon volume with liquid added to make up the gallon “space”.

Industry:Oil & gas
Valence state +2 iron in solution. In oil field operations, most solution iron is ferrous until oxygen is encountered. Precipitates at iron hydroxide when the pH exceeds 7 or when oxidized to ferric by contact with oxygen.
Industry:Oil & gas
Valence state +3 iron in solution. A very common catalyst in oil field emulsion and sludge formation. Precipitates at iron hydroxide when the pH exceeds 1.8 to 2.2 (depending on sour conditions).
