n: see flocculation.

n: In drilling-fluid terminology, a synonym for Flocculation


forming a larger mass from smaller ones by collision and sticking together.

when the drill bit in a new-drill well contacts an existing wellbore.

n: the foremost bulkhead that extends from the bottom to the freeboard deck of a drill ship. It keeps the main hull watertight if a collision occurs.

n: I. the property of atomic nuclei of having the probability of collision with a neutron. The nucleus of a lighter element is more likely to collide with a neutron than is the nucleus of a heavier element. Cross section varies with the elements and with the energy of the neutron. 2. a geological or geophysical profile of a vertical section of the earth.

n: a collision between a neutron and the nucleus of an atom of an element such as hydrogen. In such a collision, the neutrons energy is reduced by exactly the amount transferred to the nucleus with which it collided. The angle of collision and the relative mass of the nucleus determine energy loss.

n: the collision of a neutron and the nucleus of an atom in which the total energy of the neutron is absorbed by the nucleus.

n: a large body of rock that has been thrust horizontally over neighbouring rocks by compressive forces, as during the collision of two continents.

v: to steer one well away from adjacent wells to avoid collisions.

n: a special nuclear well log that produces an estimate of the relative amounts of oil, gas, or salt water in a formation. This log is electronically adjusted to reflect gamma ray emissions resulting from the collision of neutrons with chlorine atoms in the formations.

a type of log that measures salinity by use of gamma ray emission measurements from collisions of neutrons with chloride ions.

the sinking of an oceanic plate edge as a result of collision of a less dense plate.
