n: a specific layer of earth or rock that presents a contrast to other layers of different material lying above, below, or adjacent to it.

a subdivision of the classification of a sequence of rocks. A bed usually has similar lithographic features and is separated from other groupings by recognizable boundaries.

n: an interior wall that subdivides a ship or a mobile offshore drilling rig into compartments.

n: a subdivision of space on a floating offshore drilling rig, a ship, or a barge.

That quantity of petroleum which is estimated, on a given date, to be contained in known accumulations, plus those quantities already produced therefrom. Discovered Petroleum-initially-in-place may be subdivided into Commercial and Sub-commercial categori

n: (1) Any chemical that promotes the subdivision of a material phase. (2) Any chemical that promotes dispersion of particles in a fluid. Frequently, a deflocculant is inaccurately called a dispersant. Caustic soda is a dispersant but not a deflocculant.

n: a suspension of extremely fine particles in a liquid (such as colloids in a colloidal solution).

n: Subdivision of aggregates. Dispersion increases the specific surface of the particle, which results in an increase in viscosity and gel strength.

a mixture of a internal phase of solids, droplets or bubbles that stay relatively suspended in a continuous fluid.

n: a division of geologic time;a subdivision of a geologic period.

a time division of geologic time next shorter than a period.

n: the long periods of time dealt with and identified by geology. Geologic time is divided into eras (usually Cenozoic, Mesozoic, Paleozoic, and Precambrian),which are subdivided into periods and epochs. When the age of a type of rock is determined, it is assigned a place in the scale and thereafter referred to as, for example, Mesozoic rock of the Triassic period.

n: 1. one of the extremely small subdivisions of matter, as an atom or molecule. 2. a small quantity or fragment, as a single crystal or a substance that is made up of vast quantities of crystals.

n: the isolated solid in the fluid or nondispersed solid unit that some isolated solid agglomerates together.

n pi: concentrations of naturally occurring liquid or gaseous hydrocarbons in the earths crust. some part of which are currently or potentially economically extractable. Some categories of resources are (1) from the economic standpoint. economic (recoverable, commercial),marginally economic, and subeconomic;and (2) from the geological standpoint, identified (subdi- vided into measured, indicated, and inferred),and undiscovered.
