n: a diagram of a block of earth in which a series of cross sections are joined and viewed obliquely from above, to give a three-dimensional view. It is useful ill showing how formation structure and Strtigraphic thickness vary both horizontally and vertically. Also called fence diagram.

n: a crude oil characterised by a high API gravity, a high yield of low-octane gasoline, and a high yield of lubricating oil with a high pour point and a high viscosity index. Popularly, and according to an early classification system, a paraffin-base oil is a crude oil containing little or no asphalt and yielding a residue from distillation that contains paraffin wax. Compare naphthene-base oil.

n: a circuit with two or more paths through which the current flows. The total current equals the sum of the currents through the various paths;the voltage is the same throughout the circuit.

n: in casings of oil layer, people lower two or more column of oil tube volume to explore different pressure or performance oil layer. The lower part of casing isolated by packer.

n pl: the values that characterise and summarise the essential features of measurements.

n: evidence given verbally rather than in writing.

drilling only part way through a reservoir (near vertical wells).

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: (Pa) the SI metric unit of measurement for pressure and stress and a component in the measurement of viscosity. A pascal is equal to a force of 1 newton acting on an area of 1 square metre.

a unit of pressure equal to 1/100,000 of a bar.

n: the producing formation, often one that is not even sandstone. Also called pay, pay zone, and producing zone. pay string n: see production casing.

n: the layer that presents industry working value, not limited sand rock.
